Implementation of the State Policy for the Development of the Health Care System in the Conditions of European Integration on the Basis of Risk Management Strategy

The article examines the essence and peculiarities of strategic management of the development of the health care system in conditions of uncertainty and the main directions of implementation of the European integration state policy of the development of the health care system based on the risk management strategy and the assumption that the transformational processes accompanying the functioning and development of health care I encourage radical, not partial changes in the relevant system. It was found that the formation of a system of multi-level management of the functioning and development of the health care system based on risk management should cover all its subsystems and components, as well as provide for the division into several successive stages, or stages, each of which represents real changes in system during a certain period of time, taking into account the risks inherent in each level of its functioning, taking into account the interaction of various subjects, whose activities are aimed at achieving certain socially significant results. It was determined that the goal of risk management in the health care system should be considered to be the formation of a certain set of targeted measures and actions, the reduction of the actual deviation from the achievement of planned goals and objectives and the corresponding performance indicators due to the selection of a risky alternative and the minimization of losses from the risk, as well as on the basis of: using means of avoiding and reducing the degree of risk in a legal way; control and optimization of risk when it is not possible to avoid it in full; conscious acceptance of the degree of risk in the case when this decision is justified from a socio-economic, political, technological and managerial position. It is proven that under conditions of uncertainty, there is a need to build an effective risk management strategy and apply appropriate management mechanisms in the process of implementing the state policy of health care development and its integration into the European public and social space. The risk management strategy for the implementation of the state policy for the development of the health care system should be understood as a certain set of targeted measures, as well as a set of methods and means of risk identification, their forecasting and response in order to control and reduce the probability of making unreasonable decisions, the results of which may lead to negative consequences for the functioning and development of the relevant system with further analysis of the results of relevant decisions.

ADMINISTRATIVE AND LEGAL SUPPORT OF POLICE MANAGEMENT IN THE CONTEXT OF ECONOMIC INTEGRATION

The subject matter of the study is the conceptual, theoretical, empirical and methodological foundations of legal and economic aspects of administrative and legal support for the management of police activities in the context of economic integration. Methodology. The study uses general scientific and special methods of cognition. The dialectical method was used to analyse the essence of police management in the context of economic integration in both the legal and economic dimensions in a wide range of parameters. The analysis provided the basis for a multidimensional study of all the characteristic features of police management in the context of economic integration in economic and legal etymology. The synthesis created the basis for generalising the characteristic features of this police activity as a law enforcement agency. The formal legal method allowed for an accurate interpretation of the legal provisions defining the general and special legal framework for administrative and legal support of police management in the context of economic integration. The article aims at defining the essence of administrative and legal support for management of police activities in the context of economic integration and developing proposals for its improvement. The results of the publication show that the administrative and legal support of police management in the context of economic integration covers a number of comprehensive measures in various areas of activity of the relevant police unit, primarily aimed at ensuring economic security. The paper identifies areas for improving the administrative and legal support of police management in the context of economic integration, with a significant emphasis on lawmaking. Conclusion. In the context of economic globalisation, so-called transnational crimes play a significant role, including the creation of and participation in organised criminal groups, corruption offences, obstruction of justice, and money (income) laundering. The National Police of Ukraine is taking a number of measures to counteract unlawful manifestations in the economic sphere, which are largely components of transnational crime, by implementing appropriate management measures. In the context of administrative and legal support of the National Police, the article examines the structural elements of transnational crime and the powers of the police in this area. Some aspects related to combating crimes committed by organised groups and criminal organisations, corruption offences, economic crimes and the prevention of economic crime were highlighted. In order to overcome the negative manifestations of economic crime in the conditions of economic integration, relevant measures have been proposed, including: participation in legislative work, which should primarily incorporate the best practices of the international community in this area; development of the concept of service activities, which mediate the form and content of law enforcement activities in the economic sphere; improvement of management activities in combating manifestations of corruption in the economic sphere; creation of a qualified personnel potential in the relevant units of the National Police, whose activities are aimed at ensuring economic security in accordance with the above directions, etc. The paper provides proposals for improving the legislative definition of the concept of economic security and delineating the competence of national security entities in this area, including police units.

Sensorimotor integration in cranial muscles tested by short- and long-latency afferent inhibition

ObjectiveTo compressively investigate sensorimotor integration in the cranial-cervical muscles in healthy adults. MethodsShort- (SAI) and long-latency afferent (LAI) inhibition were probed in the anterior digastric (AD), the depressor anguli oris (DAO) and upper trapezius (UT) muscles. A transcranial magnetic stimulation pulse over primary motor cortex was preceded by peripheral stimulation delivered to the trigeminal, facial and accessory nerves using interstimulus intervals of 15-25 ms and 100-200 ms for SAI and LAI respectively. ResultsIn the AD, both SAI and LAI were detected following trigeminal nerve stimulation, but not following facial nerve stimulation. In the DAO, SAI was observed only following trigeminal nerve stimulation, while LAI depended only on facial nerve stimulation, only at an intensity suprathreshold for the compound motor action potential (cMAP). In the UT we could only detect LAI following accessory nerve stimulation at an intensity suprathreshold for a cMAP. ConclusionsThe results suggest that integration of sensory inputs with motor output is profoundly influenced by the type of sensory afferent involved and by the functional role played by the target muscle. SignificanceData indicate the importance of taking into account the sensory receptors involved as well as the function of the target muscle when studying sensorimotor integration, both in physiological and neurological conditions.

Fixed-point theorems of {F}^{star}- ( psi,phi ) integral-type contractive conditions on 1_{E}-complete multiplicative partial cone metric spaces over Banach algebras and applications

In this paper, we introduce some user-friendly versions of integral-type fixed-point results and give some modifications of the classical Banach contraction principle by constructing a special type of contractive restrictions of integral forms for weak contraction mappings defined on 1_{E}-complete multiplicative partial cone metric spaces over Banach algebras and formulate some existence and uniqueness results regarding the fixed-point theorems using some integrative conditions. Moreover, we validate the significance our results and exploit them to find the unique solution of a fractional nonlinear differential equation of Caputo type, which complements some previously well-known generalizations found in the literature.

Talent cultivation model of rural tourism and industry-education integration combined with the advantageous correlation degree method

Abstract In this paper, we first constructed an industry-teaching integration model for rural tourism talent cultivation and determined the objectives, content, and cultivation methods for cultivating talent. Then, the correlation analysis model is established, the principal components are extracted, and the discrete behavioral observations of the system factors are transformed into segmented continuous lines through the method of linear interpolation, and then the geometric characteristics of the lines are used to determine whether the connection between different sequences is close. Finally, a correlation analysis is conducted on the level of talent cultivation during industry-teaching integration and the factors that influence it. The results show that the training conditions of industry-education integration β = 0.283, the training mode β = 3.409, and the training content β = 0.175, which indicates that the integration of industry-education integration plays an important role in cultivating rural tourism talents. This study proposes a new talent cultivation mode to provide a theoretical basis for the sustainable development of rural tourism.

State Development Institutions in the System of Innovation Cooperation: Asian Countries Experience

In modern conditions, the main direction of the technological policy of the Russian Federation is to ensure technological sovereignty. The creation of critical and end-to-end technologies of proper development and production of goods, works and services based thereon is possible only in the conditions of integration and cooperation of research and production and technical activities. The functioning of the innovation cooperation system is impossible without the direct participation of state development institutions that perform an organizing role, ensure the creation and development of infrastructure.The paper analyzes the activities of state development institutions in Asian countries (the People’s Republic of China, Japan, the Republic of India, the Republic of Kazakhstan and the Republic of Singapore), their functions, including ensuring the commercialization of scientific research and technology transfer. The experience of building a system of innovation cooperation of these countries is of direct interest, firstly, due to the existence of developed economic relations between the Russian Federation and a number of analyzed countries, and secondly, because it was the Asian countries that managed to make a technological breakthrough in a fairly short time.The analysis showed that state development institutions in the analyzed countries are created as state-owned companies subordinate to government structures and perform functions for the implementation of state strategies for scientific and technological development. The activities of the institutions under consideration depend on the level of economic development and the chosen type (nature) of technological modernization. State development institutions are holdings, while there is a tendency to merge and consolidate them. However, the reforms carried out by states do not always have positive results.

Assessment of the operational flexibility of virtual power plants to facilitate the integration of distributed energy resources and decision-making under uncertainty

Distributed energy resources (DERs) are elements that actively participate in the supply of renewable energy and contribute to the decarbonization of the power system. However, they lack two factors necessary to take advantage of their operational flexibility: observability and controllability. In this sense, Virtual Power Plants (VPPs) are a feasible alternative to provide the necessary requirements for the optimal management of a set of distributed units. Therefore, knowledge of the technical and energy characteristics of each unit that makes up the VPP is a necessary condition for the effective integration of DERs into the power system. This paper proposes a methodology to graphically represent, quantify and exploit the aggregate operational flexibility of a set of units. The proposed methodology is based on five metrics related to active and reactive power, which serve as a tool to facilitate the VPP Operator's decision-making under uncertainty. Consequently, achieving the coordinated operation of several distributed units makes it possible to achieve common objectives. For instance, frequency and voltage regulation, compliance with a planned power curve, or dealing with the variability of renewable energies. The proposal is applied to a theoretical case study and through real operational tests between a hydroelectric unit and a photovoltaic plant. Finally, it is shown that the results obtained are a useful tool in real-time.

Innovative and financial modernization of transportation system based on international technology transfer

The object of the study is the process of innovative and financial modernization of the transport system based on international technology transfer. The problem of innovative foundations of strengthening its competitiveness in the conditions of integration into the EU has been solved. The main results obtained: disclosure of the innovative essence of technology transfer, substantiation of the organizational and economic mechanism and systematization of demand factors of the transport system for technology transfer, its financial and investment support. The obtained results are illustrated by a system of qualitative and quantitative indicators. It was established that during 2010–2019, the share of spending on the GDR in the national GDP decreased from 0.75 % to 0.43 %, but at the EU level it increased from 1.92 % to 2.14 %. The high dependence of countries on the transfer of technologies and innovations due to the negative values of their export and import balances has been proven. Their main share in 2020–2021 in the country falls on licenses – 51.39 % and 44.48 %, respectively, as well as franchises and trademarks – 38.55 % and 39.51 %, respectively. The results are explained by the lack of financial resources for the implementation of innovations, the lack of scientific research, etc. The peculiarities of the conducted research are the use of a dynamic approach for the provision of a balance between innovations and sources of their financing, of strengthening the competitive positions of the transport system in the conditions of European integration. The scope of the results is the development of strategic innovative foundations for the transport system, and the conditions for their practical use are promising tools for financial and investment support.

Social Determinants of Health and ER Utilization: Role of Information Integration during COVID-19

Emergency room (ER) admissions are the front door for the utilization of a community's health resources and serve as a valuable proxy for a community health system's capacity. While recent research suggests that social determinants of health (SDOH) are important predictors of patient health outcomes, their impact on ER utilization during the COVID-19 pandemic is not well understood. Further, the role of hospital information integration in moderating the impact of SDOH on ER utilization has not received adequate attention. Utilizing longitudinal claims data from a regional health information exchange spanning 6 years including the COVID-19 period, we study how SDOH affects ER utilization and whether effective integration of patient health information across hospitals can moderate its impact. Our results suggest that a patient's economic well-being significantly reduces future ER utilization. The magnitude of this relationship is significant when patients are treated at hospitals with high information integration but is weaker when patients receive care at hospitals with lower levels of information integration. Instead, patients' family and social support can reduce ER utilization when they are treated at hospitals with low information integration. In other words, different dimensions of SDOH are important in low versus high information integration conditions. Furthermore, predictive modeling shows that patient visit type and prior visit history can significantly improve the predictive accuracy of ER utilization. Our research implications support efforts to develop national standards for the collection and sharing of SDOH data and their use and interpretation for clinical decision making by healthcare providers and policy makers.

Strategic management of the development of small agribusiness enterprises in the conditions of strengthening competitive characters and european integration

Agriculture and the agrarian complex are really important for the development of the economy of Ukraine. Access to international markets and provision of competitive products open up new opportunities for development and attraction of investments in the agricultural sector of the country. In order to successfully enter the European market and use modern innovative technologies in production, the following aspects are necessary: innovative technologies, product quality, marketing and strategy. Strengthening the state and expanding the export of agricultural products to international markets require the introduction of innovations and improvement of product quality. This creates opportunities for the development of the agricultural sector, attracting investments and contributes to the overall economic growth of Ukraine. The article is devoted to the study of the choice of strategy for the development of small business enterprises under the conditions of European integration. The development of agricultural enterprises in the context of global integration processes and entry into European and world markets requires the implementation of modern methods of strategic development. One of the key tools for achieving success is developing a development strategy. The enterprise development strategy in the agricultural sector must take into account internal and external factors, as well as the goals and objectives of the enterprise. Some aspects that can be included in an agricultural enterprise development strategy include: marketing strategy, investment strategy, human capital development. These aspects will help the agricultural enterprise to effectively adapt to the challenges and opportunities of global integration processes and achieve success in international markets. Development strategies in agribusiness are the interaction of external and internal elements in conditions of environmental instability for the long term in order to implement the set tasks. The success of entrepreneurial activity in agribusiness is largely determined by its strategy. The presence of a single conceptual approach in agribusiness, as a complex economic system, is important in making the necessary decision. The implementation of strategic goals should ensure the survival of the enterprise for a long period of time, the effectiveness and efficiency of activities. It should be taken into account that the strategy in agriculture is difficult to adjust due to the presence of features inherent in this field: dependence on natural and climatic conditions, seasonality. the development and implementation of an innovative development strategy is an important factor for small agricultural enterprises in order to increase their profitability and profitability, expand their market presence and strengthen their competitive positions. Innovation can become a key tool for achieving success in the conditions of growing competition and integration into the European economic space.

Методологические основы формирования стратегических направлений развития регионов России

In the conditions of increasing negative hybrid impact on the country's economy and related objective and subjective factors, the development of priority areas of science and technology is of particular importance. However, the limited financial and economic resources, as well as sanctions restrictions, including on the import of components and technologies, sharply raise the question of determining strategic directions of development. And if in the conditions of global integration and cooperation, strategic directions of development depend only on the priorities established in a particular country, then in the conditions of a break in production and scientific chains, issues of developing methodological approaches to determining strategic directions of development in the context of regions and industries come to the fore. Since it is the available opportunities that should serve as the basis for developing development strategies.

"Brain Drain": dynamics and state management mechanisms of countermeasures in the conditions of European integration of Ukraine

Study of the peculiarities of the "brain drain" in the conditions of a full-scale war between Russia and Ukraine, as well as consideration and formation of management decisions regarding potential re-emigration policy, especially in the context of the academic community (teachers and scientists). The key methodological basis was the interdisciplinary approach, which made it possible to apply the work of both political scientists and state managers, as well as economists, sociologists, and psychologists, to the given problem. Dialectical and comparative methods were also important, which made it possible to reveal the contradictions and specifics of the implementation of the state policy of preventing "brain drain" and "brain gain". The authors considered data from sociological surveys, as well as statistical data published by the National Academy of Sciences of Ukraine and the Ministry of Education and Science of Ukraine, which made it possible to identify a kind of regularity – in both cases, approximately 10% of scientists/teachers were outside the borders of our country. Considering the project of the state policy of "brain growth" (more precisely, re-emigration), it was established that recommendations in this context should be formulated not only for the donor country itself but also for migrants, the recipient country, and international organizations. Using the work of not only specialists in public management and administration but also related humanities – sociology, psychology, and philosophy, makes it possible to reveal the problem of "brain drain" in our country in a multilevel and comprehensive way, thereby seeing in this problem not only a purely sociopolitical aspect but also personal and existential. Management challenges related to this issue are not only in the formation of re-emigration policy but also in preventing (or at least minimizing) academic migration in the future, which should be based on such key points as social partnership and tolerance.

Estrogenic regulation of claudin 5 and tight junction protein 1 gene expression in zebrafish: A role on blood-brain barrier?

The blood-brain barrier (BBB) is a physical interface between the blood and the brain parenchyma, playing key roles in brain homeostasis. In mammals, the BBB is established thanks to tight junctions between cerebral endothelial cells, involving claudin, occludin, and zonula occludens proteins. Estrogens have been documented to modulate BBB permeability. Interestingly, in the brain of zebrafish, the estrogen-synthesizing activity is strong due to the high expression of Aromatase B protein, encoded by the cyp19a1b gene, in radial glial cells (neural stem cells). Given the roles of estrogens in BBB function, we investigated their impact on the expression of genes involved in BBB tight junctions. We treated zebrafish embryos and adult males with 17β-estradiol and observed an increased cerebral expression of tight junction and claudin 5 genes in adult males only. In females, treatment with the nuclear estrogen receptor antagonist (ICI182,780 ) had no impact. Interestingly, telencephalic injuries performed in males decreased tight junction gene expression that was partially reversed with 17β-estradiol. This was further confirmed by extravasation experiments of Evans blue showing that estrogenic treatment limits BBB leakage. We also highlighted the intimate links between endothelial cells and neural stem cells, suggesting that cholesterol and peripheral steroids could be taken up by endothelial cells and used as precursors for estrogen synthesis by neural stem cells. Together, our results show that zebrafish provides an alternative model to further investigate the role of steroids on the expression of genes involved in BBB integrity, both in constitutive and regenerative physiological conditions. The link we described between capillaries endothelial cells and steroidogenic neural cells encourages the use of this model in understanding the mechanisms by which peripheral steroids get into neural tissue and modulate neurogenic activity.

Eurasian Economic Solidarity: Justification from the Standpoint of Judicial Practice

Aim. The purpose of the study is to substantiate the concept of Eurasian economic solidarity in the context of the practice of the court of the Eurasian Economic Union.Tasks. The objectives of the study are: highlighting the sign of publicity in the context of economic integration; analysis of existing scientific and normative approaches to solidarity; substantiation of Eurasian economic solidarity as a principle and value of economic interaction, formed, inter alia, through judicial practice.Methods. The following methods were used: institutional analysis, comparative analysis, system analysis — to substantiate the sign of publicity in the context of economic integration, to characterize the Eurasian economic solidarity as a principle and value of economic interaction within the framework of the common economic space of the EAEU, to highlight the practice of the EAEU court as a factor in the formation of the Eurasian economic solidarity. The method of formal-logical analysis was also used — in clarifying the concepts of “solidarity” and “economic solidarity”.Results. Firstly, the activity of the EAEU Court reflects international or integration normative control, which is an integral part of public control and supervision in the conditions of integration. In the context of economic integration, the sign of “publicity” in relation to control and supervision as basic management functions is naturally supplemented by an integration level. Secondly, the supranational bodies of the EAEU, including the Court of the EAEU, are able to form and ensure economic solidarity in the context of Eurasian integration. Thirdly, Eurasian economic solidarity is seen as the principle and value of economic interaction within the framework of a single economic territory.Conclusions. Eurasian economic solidarity is based on economic unity, but is not conditioned by it. It is formed in the processes of integration rule-making and law enforcement. Eurasian economic solidarity is closely connected with other types of solidarity: ethnic, social, etc. Dispute resolution and interpretation by the EAEU Court act as a means of forming common economic positions within the EAEU. The EAEU Court has a sufficient and not fully realized potential to influence the development of Eurasian integration, including by stimulating the development of Eurasian economic solidarity. Equal access of economic entities of the EAEU member states to justice for the protection of economic rights is a condition for Eurasian economic solidarity.

The Strategic Role of Iran for the SCO: Strengthening Eurasian Integration

The process of integration in the Eurasian region is important for all states and after the 2014 Ukraine crisis, Russia’s greater Eurasian policy and the expansion of the Shanghai Cooperation Organization (SCO), the conditions for integration have become more suitable than before. After a decade and a half of observer membership, Iran has finally become an official member of SCO in 2022, and it seems that due to the wide territorial contiguity from the borders of Türkiye to Afghanistan, new possibilities for regional integration have been created. This article is written with the aim of discussing Iran’s role in Eurasian integration after the membership in the SCO. The main question in this article is that how Iran can contribute to Eurasian regional integration within the framework of this organization? The author’s idea is that Iran’s membership in the SCO, through the increasing expansion of the connections of the Eurasian region to South Asia and the Middle East, provides more opportunities for cooperation in confronting the sources of regional insecurity, cooperation in the field of trade and the expansion of regional transport and communications and this issue can contribute to economic development, security and broader regional integration in the region. The author has tried to use the theory of regional integration and the method of qualitative content analysis of documents, texts, reports and news related to the Eurasian integration to verify the hypothesis. The findings of this research show that the greater Eurasian region needs a wider integration in the fields of economy, trade, communication and transportation, and the solution to reduce its problems is possible through the cooperation of all effective regional actors, and Iran is also one of the effective countries that has been a missing linkage in Eurasian integration and any comprehensive security and economic integration in Eurasia requires its active participation, which an official member of the SCO has created this opportunity.

By understanding and effectively managing the conditions of European integration, companies can take advantage of this huge market potential, expand their reach and drive sustainable growth. The purpose of the paper is to illuminate and reveal the importance of managing the development of recreational innovative companies in the context of European integration. Results. In the paper, the importance of innovative management in the recreational sphere is considered, in particular in the context of European integration. The authors emphasize the role of sustainable development, digital transformation, joint innovation and compliance with regulatory requirements in ensuring the competitiveness of companies. The importance of strong leadership and strategic decisions for the successful development of companies in the recreational sector is also highlighted. An algorithm for managing the development of innovative recreational companies in the context of European integration is proposed, following which Ukrainian recreational companies can navigate the complexities of European integration while effectively managing their innovative development. Strong leadership combined with strategic decision-making and adaptation will ensure these companies succeed in the European market. Conclusion. Managing the growth of recreational innovation companies requires attention to market competition, quality and safety standards, changes in legislation and the regulatory environment, and consumer needs. The development of innovative products and services that take into account the principles of sustainable development can attract more customers and increase more interest in the market.

The investment component of the development of the agrarian sector of the economy of Ukraine in the conditions of european integration: problems and prospects

The article examines the problems of investment support in the agricultural sector of Ukraine's economy in modern conditions and identifies promising directions for improving the investment climate. It has been established that in the process of creating a market economy in Ukraine and European integration processes, there is a need for complex searches for ways of development and determination of the role and place of the state in these economic transformations. The experience of developed democratic countries shows that there is no single solution to this problem, and the degree of state intervention in the economy of different countries varies. The directions of the transformation of the agrarian-industrial complex in Ukraine since independence have been determined. It has been proven that before the start of the full-scale war, the agricultural sector in Ukraine was one of the most profitable branches of the Ukrainian economy. It contributed to a significant contribution to the GDP and preservation of land resources in a satisfactory condition. A number of problems in the agrarian sector of Ukraine's economy, which inhibit its development, are highlighted: insufficient transparency in matters of land ownership; non-compliance with quality and safety standards established by international organizations; limited investment level; insufficient adaptation of Ukrainian legislation to the requirements of the European Union; the problem of reforming the market and its structure; dependence on state funding; lack of innovative activity; problems in the field of logistics and supplies. The assessment of direct losses in the field of agro-industrial complex and agricultural infrastructure, which were the result of constant attacks by the Russian armed forces, is presented. Among the components of these losses, the largest ones that have become the most financially significant should be indicated: agricultural machinery, finished agricultural products, and grain storages. It is these losses that can be recognized as significant and such that they do not allow us to talk about the rapid improvement of the situation in the agricultural sector of Ukraine and the attraction of investments. The main vectors of increasing the investment attractiveness of the agrarian sector of the Ukrainian economy are given and a list of measures that must be taken to solve the main problems of the agrarian sector of Ukraine during and after the war, as well as improving the investment component of the development of the agrarian sector of the economy and continuing the European integration processes, is presented.

Framework for fast and low-complexity deployment of UAVs-assisted communication

Unmanned Aerial Vehicles (UAVs) can work as aerial base stations along with the ground base stations to enhance capacity and provide ubiquitous coverage in 5G and beyond communication systems. UAVs have numerous features that distinguish them from the traditional fixed ground network infrastructure. These features include more flexibility, lower costs, faster integration, and better channel conditions with users owing to the UAVs maneuverability and adaptability to varying network conditions. This paper addresses UAVs positioning and radio resource management, which are two critical design issues that greatly impact the system performance and user experience in UAVs-assisted communication scenarios. Our objective is maximizing the achieved sum rate of a system consisting of a ground base station and a number of UAVs operating as aerial base stations under constraints on the minimum rate requirements of users, the capacity of wireless backhaul links between the UAVs and the ground base station, and the power budgets of the base stations. In doing so, we optimize the UAVs locations, the users-to-base stations association, the access link channels assignment, and the power allocation. The problem is a mixed-integer non-convex optimization, which is NP-hard to solve, and consequently we propose a fast low-complexity algorithm that achieves high performance compared to the common block coordinate descent-based solution approach and at much less execution time.

Configuration of Conditions Leading to High National Innovation Competitiveness: A Fuzzy Set Qualitative Comparative Analysis Approach

Under the conditions of economic integration and globalization, the importance of national innovation competitiveness is rapidly increasing. In order to study what combination of conditions can generate higher national innovation competitiveness, this study proposes an improved integrated framework for national innovation competitiveness and it examines the allocation conditions that affect the innovation competitiveness of countries with different income levels using data from the Global Competitiveness Report 2019. This research finds that, first, the means of achieving high innovation competitiveness output are more diversified for high-income and upper-middle-income countries, with countries at these two economic levels achieving high innovation competitiveness output in three scenarios. Second, lower-middle-income countries have a more homogeneous configuration for achieving high innovation competitiveness outputs, with only one scenario, which still holds after a series of robustness tests. Third, for high-income countries, commercialization is a key element affecting their innovation competitiveness enhancement. The study not only bridges the gap between existing theories and research methods but also provides a useful reference for countries at different levels of economic development to improve their innovation competitiveness.
