FORMALIZATION OF THE CONCEPTUAL PROVISIONS OF THE STATE POLICY FOR THE DEVELOPMENT OF HIGH-TECH INDUSTRIES AND THE INFORMATION AND COMMUNICATION TECHNOLOGY SECTOR ACCORDING TO WORLD EXPERIENCE

The article highlights the need to study world experience as a basic element in the development and implementation of state policy, especially in the field of high-tech and digital economic development. The importance of a comprehensive approach to the construction of the state policy for the development of high-tech industries and the ICT sector is emphasized and its main elements are highlighted: the purpose, goals, subjects, objects, functions, principles, methods, tools, means. In the context of the study of the world experience of the implementation of such a state policy, attention is focused on the processes of resource provision, infrastructural development, normative and legal regulation, institutional and organizational management, production and technological development, investment and innovation activities, information and communication exchange and others. The study of the world experience of the state policy of the development of high-tech industries and the ICT sector makes it possible to note that the state acts as a driving force in creating a favorable environment for the stable establishment and expansion of the production and sale of high-tech products with a high level of implementation of digitization processes. The experience of developed countries confirms the priority of the state policy for the development of high-tech industries and the ICT sector with the following leading strategic goals: the formation of the internal market of innovations and technologies and its integration into the country’s economic system; development and implementation of progressive projects of high-tech production and digitization of the economy; improvement of organizational-technical and financial-economic accessibility of innovations and digital technologies; creation and development of innovative technological and informational digital infrastructure; development of inter-branch and inter-sectoral technical-technological and information-communication cooperation; creation and development of the national ecosystem of digital and technological transformation.

What Kind of Market Is Conducive to the Development of High-Tech Industry? Configuration Analysis Based on Market Field Theory

The high-tech industry is important in supporting China’s construction of a high-quality modern economic system. The high-tech industry markets are spaces for the supply and transaction of high-tech products. The existing research lacks in-depth discussions on the constituent factors and shaping mechanisms of the high-tech industry market. This paper constructs the market field configuration model of the high-tech industry and studies the impact of the market field configuration of the high-tech industry in 30 provinces of China on the innovation performance of the high-tech industry using the fuzzy-set qualitative comparative analysis method. The findings are as follows: (1) The three structural variables of network, institution, and cognition cannot individually constitute the necessary conditions for explaining the high or low innovation performance of high-tech industries; (2) Three high-tech industry market field configurations can lead to high innovation performance, and the condition combination among different configurations has a substitution effect; (3) Four high-tech industry market field configurations will lead to low innovation performance, in which the lack of multiple conditions in the network, system, and cognition is the main reason for the market failure. The research conclusions of this study highlight the cognitive role of market construction and the configuration characteristics of effective high-tech industry market fields, which provides practical enlightenment for China to improve the innovation performance of high-tech industries.

Organizational and technical level of preparation of shipbuilding and ship repair production and ways to improve it

A set of problems of a shipbuilding and ship repair plant in terms of production preparation efficiency, focusing on such issues as import substitution, modernization, the introduction of innovative solutions in production, digitalization of production, is studied in the paper. Considerable attention is paid to the real state of the shipbuilding industry, the difficulties it faces, and the prospects for restoring specific positions. A set of issues related to the shipbuilding and ship repair production organization is considered. Attention is paid to the production efficiency, taking into account the fact that the efficiency of shipbuilding and ship repair production in modern Russia is characterized by the development of high-tech science-intensive industries and the introduction of innovative technologies. It is concluded that modern high-tech shipbuilding and ship repair production requires the involvement of significant financial and intellectual resources, and production facilities must be provided with modern, mostly automated production equipment, slipways, docks, boathouses, so it is necessary to take specific measures towards a significant improvement in performance, characterizing the state of fixed production assets. On the example of Onego Shipyard, JSC, the trend towards production modernization and the prospects for production and economic development are shown; it requires significant investment in the technical re-equipment and production modernization, and also contributes to the creation of a new production infrastructure and a significant renewal of fixed assets. Considerable attention should be paid to the issues of a systematic approach to solving the problems of shipbuilding and ship repair production, taking into account the organizational and technical component.

Research on Urban Monitoring Network Management Platform based on AI Data Stream Processing

In recent years, with the upsurge of the continuous development of high-tech information industry, the security industry has also made a new leap in technology, products, industry and so on. The traditional single small-scale monitoring and management software obviously cannot meet the actual needs of users in terms of system scale and functional requirements. This paper puts forward a network management platform for urban monitoring based on AI data stream processing. With the help of comprehensive processing and analysis of urban complex information, through network remote monitoring means, information supervision and public opinion trends are used to control social environmental security, timely warning and response to unexpected accidents, so as to ensure that governance departments can fully control and prevent possible problems such as road traffic, population distribution and disaster emergency.

Measuring the Development Capability of the Innovation Ecosystem from a Quadruple Helix Perspective—An Empirical Analysis Based on Panel Data for Chinese High-Tech Industries

With the rapid development of high-tech industries, the research perspective of industrial innovation has gradually evolved from the innovation system to innovation ecosystem. Whether the innovation ecosystem of China’s high-tech industry can achieve the benign evolution and development of the system under the new global pattern has become a real issue. Based on the perspective of the four-helix innovation model, in this study we construct an index system of the industrial innovation ecosystem development and designs a framework system of the industrial innovation ecosystem development capability, including the coordinated development capability, evolutionary development capability, and sustainable development capability at three levels. We construct measurement models of different capability dimensions and multi-dimensionally analyses of the regional development differences and change trends of each capability dimension of the system. The results show that the coordinated development capability of China’s high-tech industrial innovation ecosystem is poor, which inhibits the comprehensive capability of the system’s development to a certain extent. Although the evolutionary and sustainable development capabilities fluctuate greatly and have significant regional differences, they are measured at a better level and thereby contribute to the development of the system.

Features of Soviet Industrial Development in 1957–1964 (On the Example of the Mari, Mordovian and Chuvash Autonomous Soviet Socialist Republics)

Introduction and Methods. The relevance of the work is due to the demand for the experience of the economic council reform, including its regional aspect, at the present stage of Russian modernization. The basis of the methodology of the work is the modernization historical paradigm, aimed at the study of various kinds of progressive transformations of society, noted in the process of its development. The main methods used are comparative-historical, historical-cultural, problem-chronological. Results and Discussion. The economic councils of the Mari, Mordovian and Chuvash economic administrative regions already in the first years of their existence showed very worthy economic results. The decentralization of the economic sphere, the removal of bureaucratic “obstacles” stimulated the rapid development of new high-tech industries in all three republics: electrical, machine-building, metalworking, instrument-making, etc. However, having given the industrial development of the Mari, Mordovian and Chuvash Autonomous Soviet Socialist Republics a maximum exhausted itself quickly. Founded in the early 1960s the crisis phenomena were expressed in the growth of isolation of the economic regions headed by economic councils as economic cells striving for self-sufficiency (autarky), which gave rise to a number of problems, in particular in matters of supplies between different economic regions, in drawing up plans and their implementation. The regional material of the studied republics eloquently testifies to the typical (universal) nature of such negative manifestations. Conclusion. For the Mari, Mordovian and Chuvash Autonomous Soviet Socialist Republics, the main result of the economic reform was, in fact, their synchronous transformation from agrarian-industrial to industrial-agrarian regions. The rather rapid pace of this process (1957–1964) can be explained by the decentralization of the economy that occurred as a result of the economic reform, which brought management closer to production and unloaded the industrial management system from excessive bureaucracy. However, the effect of decentralization turned out to be extremely short-lived, since the shortcomings of the territorial administration system soon showed themselves, leading to the rapid exhaustion of its capabilities.

Strategic Policy Innovation of Regional Development Strategy Transformation in the New Era Based on Progressive Differential Model

Abstract In the new era, the national high-tech industrial development Zone is a powerful platform for implementing the innovation-driven development strategy and promoting China’s high-level development. An empirical study of panel data from 285 county-level cities in China during 2001-2022 was conducted using the binary difference method. The results show that high-tech enterprises have a noticeable promoting effect on improving the quantity of industrial structure. The transformation and upgrading of our industrial design by high-tech enterprises have significant cyclical heterogeneity. It has significantly enhanced the industrial system compared with the “growth type” and “mature type” national high-tech development zones. There is no apparent regional difference in the quality effect of high-tech enterprises on industrial structure upgrading. Still, there is an evident regional difference in the quantity and rationality of industrial structure height.

Strategy of transition to a new world economic order and noosociety: industrial aspect

Contemporary transformation of the economic and social system requires changes in approach to its analysis and in management of its development. At the same time, in the author’s opinion, there is no need to keep the traditional approach based on the neoliberal theory and methodology. For Russia, the Chinese experience is more suitable, based on the dosed and proportional combination of elements of market-based and planned models of economy management. It is precisely this approach that delivers sustainable technological, economic and social development, in process of which the tasks of qualitative renewal of all fields of public life are solved. And in addition, the central focus is made in the development of high-tech industries, which are becoming a core of an economic and social system being renewed. This requires top-priority development of fundamental science, culture and education, as well as the return of the state into capitalist process, to the direct public administration of a number of development spheres, active support of state and public-private high-tech corporations. The basis of the development is technological advance. It also changes in new conditions. A new quality of industrialized production is observed. It is knowledge-intensive production, for which not only a speed-up is typical, but also a speed-up of speed-up of technological development. Today, Russia solves tasks not only in industrialization or reindustrialization: such tasks will be mostly solved anytime soon; but also is facing the task of creating the basis of the new industrial society of the second generation (NIS.2), a society where knowledge takes the leading role. The latter means the priority of knowledge-intense production united with science and education. Hence, a necessity arises to integrate those three spheres within the frame of united reproduction contour on all levels: mirco-, meso- and macroeconomics. To solve this task, an active industrial policy and strategic planning are essential, together with the activity of private funds and orientation to social interests of public sector. Author has explored and elaborately describes in details a toolset necessary for that in the article.

Ecological assessment of Uncle Sam Gulch Creek water quality under conditions of acid mine drainage

The current stage of subsurface use development is accompanied by an annual increase in post-mining territories. This is partly due to a change in funding priorities in this area and their widespread reorientation to the search for alternative sources of raw materials to ensure the development of modern high-tech industries. One of the biggest threats to the environment in this development is the deterioration of the freshwater quality due to poor management of abandoned mining areas. And one of the most significant problems is often created by acid mine drainage. As a part of the study, information on the current environmental state of a past American mining territory located near Basin, Montana, USA, was analyzed and summarized; a conceptual exposure model was created regarding the studied natural and technogenic interactions; systematization and data updating on temporal and spatial changes in the qualitative characteristics of surface waters that are in direct contact with the abandoned mine were carried out; the level of efficiency of implemented reclamation works on the territory was determined. The results of the water quality environmental assessments proved that the measures taken thus far are absent of a sufficient level of effectiveness for its full rehabilitation. To accelerate the process of changing the water quality of the investigated water object, both in terms of condition and degree of purity, a combination of a passive treatment system coupled with an artificial reduction of acid mine drainage volumes was suggested.

Financial Technology and the Economic Performance of High-tech Industries: A Comprehensive Research based on Econometric Model

High-tech industries play a pivotal role in driving the high-quality economic development of contemporary China. Financial technology, characterized by innovation as its core driver, offers indispensable support and strategic direction for the advancement of high-tech industries. Applying the Peking University Digital Financial Inclusion Index from 2011 to 2020, this paper explores the correlation effects of financial technology on the economic performance of high-tech industries (EPHI). The result reveals that: (1) digital finance enhances EPHI. (2) in terms of decomposition terms, both the coverage breadth and usage depth of digital finance have a significant positive impact on EPHI. (3) reginal heterogeneity studies show that digital finance increases EPHI in developed provinces more significantly. (4) technology innovation plays a part in mediating the process of digital finance to enhance EPHI. This paper adds new empirical evidence to the long-term government policy for the development of high-tech industries.

INNOVATION INFRASTRUCTURE AS A FOUNDATION FOR BUSINESS PROCESS DEVELOPMENT

Innovation infrastructure is most often associated with research activities and high-tech production. From a strategic point of view, innovation infrastructure ensures the process of realization of new or improved products, processes or production methods, thus creating the basis for highly efficient activities. In this sense, the formation of innovative infrastructure is extremely important for Ukraine as a basis for the development of high-tech industries and increasing the efficiency of business processes. Methodology. The article presents the authors' method of calculating the formation of innovation infrastructure as a basis for the development of effective business processes. According to it, it is a set of objects that create conditions for innovation and the presence of such objects can conclude the formation of innovation infrastructure. The proposed methodological approach consists of three blocks, including target block, preparation unit, evaluation and diagnostic unit. In this case the object of evaluation is innovation infrastructure. Therefore, the evaluation process should determine the level of innovation infrastructure formation. Results. On the basis of the scores of the indicators of formation of innovation infrastructure, on the one hand, it is proposed to determine a generalized score of formation of innovation infrastructure by oblasts, and on the other – an integrated specific score by provision of its facilities. Thus, the main indicators for assessing the formation of innovation infrastructure are the number of technology parks, the number of industrial parks, the number of science parks, the number of business incubators, the number of innovation centers, the number of free economic zones (with intellectual property units), the number of regional science centers. The correspondence of separate objects of innovation infrastructure with the stages of innovation process provided by them is given. It is determined that technology parks provide generation, transfer and development of knowledge, innovation centers – generation and transfer of knowledge, business incubators – acquisition and use of knowledge. Taking into account this comparative characteristic, the weight coefficients of each object of innovation infrastructure are determined. On the basis of concretization, the average score of formation of innovation infrastructure in oblasts is determined, which corresponds to the integrated score of formation of innovation infrastructure of Ukraine. Practical implications. The rating of the effectiveness of innovation infrastructure by oblasts was calculated. The top five leaders are: Kharkiv, Zaporizhzhia, Lviv, Dnipro, and Kyiv Oblasts and the city of Kyiv itself. The efficiency rating of the leading oblasts almost completely coincides with the indicator of innovation infrastructure development, with the exception of Donetsk Oblast, which has a better indicator of development than efficiency, and Zaporizhzhia Oblast, on the contrary, has an efficient infrastructure despite its low development.

Do the High-Tech Industrial Development Zones Foster Urban Innovation? A Case Study of China

China’s high-tech industrial development zones (HIDZs) is a key “place-based” policy targeting national innovation-driven development. Despite the extensive research on HIDZs, it remains unclear whether and to what extent the policy has fostered cities’ innovation output and quality. Basing our research on panel data of Chinese cities from 2001 to 2019, we employed the PSM-DID model to examine the impact of HIDZs policy on their host cities’ innovation output and quality. The empirical results show that: (1) In general, the establishment of HIDZs has a more significant positive effect on fostering urban innovation output compared to its role in promoting urban innovation quality. However, (2) the effect on urban innovation output and quality varies across different cities. For cities with more advantageous locations and policies, HIDZ policy plays a more instrumental role in promoting the quality of urban innovation, while the establishment of HIDZs in other cities is more conducive to increasing the output of urban innovation. Ultimately, we argue that authorities must recognize the importance of integrated development of HIDZs and their host cities and incorporating HIDZs’ impact on the host cities into the HIDZ evaluation. It is necessary to understand that HIDZs have multiple development modes due to their specific local conditions. Hence, differentiated guidance must be carried out rather than directly replicating the experience from developed regions.

The necessity of others: Entrepreneurial self-efficacy, TMT collective efficacy, CEO-TMT interface, and entrepreneurial orientation.

Entrepreneurial orientation is the key factor for enterprises to obtain competitive advantages in dynamic circumstances. Thus, prior studies established the effect of psychological factors, for instance, entrepreneurial self-efficacy on entrepreneurial orientation using social cognitive theory. However, prior studies presented two main opposite views consisting of a positive and negative relationship between entrepreneurial self-efficacy and entrepreneurial orientation as well as providing no alleyway to enrich this relationship. We join the conversation on the positive linkage and argue on the essence of exploring the black box mechanisms to strengthen enterprises' entrepreneurial orientation. We employed the social cognitive theory and collected 220 valid responses from CEOs and TMTs from 10 enterprises in the high-tech industrial development zones of nine provinces in China to clarify the effect of top management team (TMT) collective efficacy, and CEO-TMT interface on the link between entrepreneurial self-efficacy and entrepreneurial orientation. Our findings show that entrepreneurial self-efficacy positively affects entrepreneurial orientation. In addition, we found that a higher level of TMT collective efficacy strengthens the positive relationship between entrepreneurial self-efficacy and entrepreneurial orientation. Moreover, we discovered differential moderating effects. First, CEO-TMT interface positively affects entrepreneurial orientation when it interacts with TMT collective efficacy and entrepreneurial self-efficacy. Second, CEO-TMT interface has a significant negative indirect effect on entrepreneurial orientation, when it only interacts with TMT collective efficacy. Our study enriches the entrepreneurial orientation literature by positioning TMT collective efficacy and CEO-TMT interface as social cognitive mechanisms underlying the development of entrepreneurial self-efficacy and entrepreneurial orientation nexus. Thus, we open a window of opportunities for CEOs and decision-makers to maintain a sustainable position in the market, grasping more opportunities in uncertain conditions via timely entries into new markets and maintaining pre-existing ones.

An Improved TOPSIS Within the DEA Framework

Decision-maker (DM) can assign the weights of the distance measures in the relative closeness of technique for order preference by similarity to ideal solution (TOPSIS) for achieving his/her desirable ranking of alternatives. This phenomenon is called strategically setting distance measure weights in this study, which may affect the fairness of the results. In order to prevent this phenomenon, the idea of data envelopment analysis (DEA) is introduced to determine the objective weights of distance measures, and an improved TOPSIS is proposed in this study. The proposed method not only determines weights of the distance measures from an objective perspective and achieves the fully ranking of alternatives, but also provides the directions for improvement. Moreover, in comparison with the other methods, the advantages of the proposed method are analyzed, and the meanings and properties of the new relative closeness are discussed and proved. Finally, an example of evaluating the innovation development of high-tech industries in central and western regions of China is investigated to illustrate the effectiveness and the usefulness of the proposed method.

Development zone policy and urban carbon emissions: empirical evidence from the construction of national high-tech industrial development zones in China.

As a key strategy to promote system reform, improve the investment environment, and encourage industrial agglomeration, the national high-tech industrial development zone (NHTDZ) policy in China can not only reduce energy consumption through the scale effect but also improve energy efficiency by modernizing industrial structure and fostering technological innovation, thereby alleviating environmental pollution. Existing studies, however, focus solely on the effects of NHTDZ policy on social and economic development, ignoring their impact on the ecological environment, especially carbon (CO2) emissions that contribute to global warming. Thus, this article analyzes a panel data of 285 prefecture-level cities and above in China from 2003 to 2019 to assess the influence of NHTDZ policy on CO2 emissions, treating the NHTDZ construction since 1988 as a quasi-natural experiment. The results indicate that the NHTDZ policy would mitigate urban carbon emissions, particularly in middle, southeastern, medium-sized, resource-based (RB), non-key environmental protection (non-KEP), and non-two control zone (non-TCZ) cities. In addition, the mediation mechanism test demonstrates that the environmental benefits of the NHTDZ policy in China are attributable to the scale effect, the structural upgrading effect, and the technology innovation effect. The NHTDZ policy would lower per capita CO2 emissions by reducing energy consumption, upgrading industrial structure, and promoting green technology innovation.

Research on the Construction of Manufacturing Industry Chain Ecosystem—A Case Study of Tianjin Manufacturing Industry

This study takes Tianjin as an example to analyze how to build the manufacturing industry chain ecosystem. Based on the ecosystem theory, the related literature of manufacturing industry chain and value chain, and combined with various action plans for the development of manufacturing industry in Tianjin, the structure chart and construction roadmap of industrial chain ecosystem were drawn. Based on the input–output data of 42 sectors in Tianjin, this study calculated and analyzed the changes in embedment degree of various manufacturing industries in Global Value Chain (GVC) and National Value Chain (NVC) in Tianjin from 2010 to 2017. It is found that the industrial chain ecosystem is mainly composed of four elements: the enterprises on the industrial chain, the information flowing among enterprises, the goods circulating among enterprises, and the external environment of enterprises. The connection of supply and demand chains, enterprise chains, space chains and value chains forms an industrial chain, and the value chain is a crucial relationship chain in the connection mechanism. In addition, 2015 is a turning point for Tianjin manufacturing industry to embed in GVC and NVC, mainly due to the industrial economic adjustment in Tianjin, the global economic turmoil, and the establishment of the manufacturing industrial park. In terms of R&D intensity, high and medium high-tech manufacturing industries tend to be embedded in GVC, but are easily affected by enterprises and environmental factors. However, low and medium low-tech manufacturing industries still have ample space to integrate into GVC, information and products are important factors to determine the upgrading of its industrial chain. Therefore, in order to better construct the industrial chain ecosystem of manufacturing industry and enhance the industrial competitiveness of Tianjin’s manufacturing industry, it is necessary to give priority to the development of high-tech manufacturing industry, expand the international openness of low-tech manufacturing industry, support regional advantageous industries, and carry out dynamic regulation of industrial ecology.

ЗАСТОСУВАННЯ ІМПУЛЬСНОГО БАР’ЄРНОГО РОЗРЯДУ ДЛЯ ОБРОБКИ ПОВЕРХНІ ПЛАСТИН ЗІ СТАЛІ МАРКИ 25ХГНМТ

The development of high-tech industries stimulates the growth of requirements to metal structures and a complex of their main and special properties. The use of pulsed electrical discharges, plasma currents, pulsed electromagnetic fields, and their combined effects to improve the mechanical characteristics of metals and alloys is relevant in connec-tion with the need in replacing traditional energy-intensive technologies of structural materials with more advanced ones. The use of pulsed barrier discharge (PBD) in metal treatment, which generates a low-temperature plasma on the surface of the metal being treated, is a new approach to optimize the mechanical properties of metal materials, which is based on electrophysical processes. In the work, strengthening of structural 25KhGNMT steel as a result of the action of PBD on its surface was studied. The treatment of steel by PBD took place in a discharge device at a voltage incre-ment rate of ≈3•1011V/s. The influence of the duration of PBD treatment on the value of Vickers hardness (HV) of the test samples was studied. The study of the structure of 25KhGNMT steel was carried out by the method of transmission electron microscopy in order to determine its changes as a result of the action of PBD. It was established that HV val-ues after PBD treatment increase from 420 to 500 kg/mm2, which is accompanied by microstructure dispersion, which positively affects the mechanical characteristics of 25KhGNMT steel.
