Coping strategies and food insecurity experiences: the case of female-headed agricultural households in Liberia

PurposeRealities of food insecurity are more pronounced with a specific focus on women in developing countries. The need to understand the varied food insecurity experiences among female-headed agricultural households in such contexts provided the rationale and motivation for this study.Design/methodology/approachThe study employed a quantitative cross-sectional approach, drawing on the binary logistic regression to determine the influence of socioeconomic status on household coping mechanisms in response to food insecurity in a stratified random sample of 509 female-headed agricultural households in Liberia.FindingsThe results revealed that most respondents experienced food insecurity reflected in inadequate food availability, an inability to eat nutritious food and the necessity to skip meals. In response, they employed coping strategies such as borrowing money, selling assets, and reducing health expenses, which were influenced by socioeconomic characteristics such as gender, education, and marital status.Practical implicationsThe study illustrates the multi-layered and complex context of food insecurity among women. From these findings, the study proposes the consideration of such dynamics to inform practical and relevant mitigatory policy approaches to the target demographic.Social implicationsWith food insecurity being a social problem, the study identifies its social impact by documenting the participants' lived experiences. Thus, the study contributes to a deeper understanding of food insecurity across different segments of society.Originality/valueThe study draws its originality from understanding how food insecurity impacts female-headed households, highlighting the often-ignored gender dynamics of food insecurity in developing nations and aggregating the coping strategies and food insecurity expenses.

[Retrospective analysis of diagnosis and treatment of tuberculosis in designated medical institutions in China from 2017 to 2022].

Objective: To understand the status of tuberculosis diagnosis and treatment capacity and the development and changes of tuberculosis diagnosis and treatment in provincial and municipal designated medical institutions in China from 2017 to 2022, so as to provide a basis for the formulation of relevant policies for the improvement and development of designated medical institutions for tuberculosis and the tuberculosis prevention and treatment service system, and to provide reasonable support for further strengthening the capacity of designated medical institutions for tuberculosis. Methods: This study was initiated and carried out by Beijing Chest Hospital affiliated to Capital Medical University/Clinical Center for Tuberculosis Prevention and Control of China CDC (hereinafter referred to as "Clinical Center") by means of questionnaire survey, and the investigation was carried out from March to November 2023. During this period, the clinical center distributed questionnaires to the hospital member units of "Beijing Tuberculosis Diagnosis and Treatment Technology Innovation Alliance", retrospectively collected their tuberculosis-related diagnosis and treatment data from 2017 to 2022, and used descriptive statistical methods to analyze the number of tuberculosis beds, outpatients and hospitalizations in medical institutions. The results were expressed in absolute numbers (percentages), and three-line tables, bar charts and line charts were drawn to describe the analysis results and changing trends. Results: The 54 medical institutions surveyed in this survey included 21 provincial-level designated medical institutions and 33 prefecture-level designated medical institutions. Most medical institutions have set up clinical departments, auxiliary departments and functional departments to undertake public health tasks of infectious diseases. The tuberculosis laboratory in the hospital has a comprehensive ability and has the detection technology needed for most tuberculosis diagnosis; The number of tuberculosis beds, children's tuberculosis beds and ICU beds all showed an increasing trend from 2017 to 2022. The proportion of tuberculosis beds in the hospital decreased slightly, from 39.31% in 2017 to 34.76% in 2022, showing a slight downward trend. Compared with the hospital surveyed, the number of tuberculosis outpatients in 2019 was 562 029, and the number of outpatients in 2020-2022 was 462 328, 519 630 and 424 069 respectively, which was significantly lower than that in 2019. The number of tuberculosis outpatients in medical institutions decreased significantly from 2020 to 2022. By analyzing the proportion of patients with different types of tuberculosis, the proportion of sensitive tuberculosis outpatients in 2017-2022 decreased from 84.49% in 2017 to 78.05% in 2022, showing a downward trend year by year. The proportion of patients with multidrug-resistant/ rifampin-resistant tuberculosis increased from 2.03% in 2017 to 7.18% in 2022. From 2017 to 2019, the total number of inpatients with tuberculosis showed an upward trend. Compared with 2019, the number of inpatients in 2020, 2021 and 2022 showed a downward trend, and the decline in 2020 was large (down 14.94% compared with 2019). Among the inpatients, the absolute number and proportion of patients with sensitive pulmonary tuberculosis remained relatively stable, and the number and proportion of inpatients with multidrug-resistant/rifampin-resistant pulmonary tuberculosis increased year by year. Conclusions: Most medical institutions have the capacity to carry out routine diagnosis and treatment of tuberculosis, but the public health function needs to be strengthened. The transformation of medical institutions requires proper guidance and adequate support. During 2019-2022, most medical institutions were affected by the COVID-19 epidemic, and their tuberculosis diagnosis and treatment work also changed to varying degrees. During this period, hospitals took various measures to overcome difficulties and tried their best to maintain the normal development of tuberculosis diagnosis and treatment, and the tuberculosis diagnosis and treatment work of various institutions gradually resumed in 2022.

Decision Analysis of Cold Chain Supply Chain Based on a Stochastic Evolution Model

Accelerating the development of cold chain logistics for agricultural products is not only an objective requirement for the development of agricultural product circulation but also a necessary demand to promote rural revitalization and upgrade agricultural consumption. Addressing the evolutionary problems of cold chain transportation in uncertain environments, this study considers the actual stochastic disturbances in the cold chain supply chain system, introducing Gaussian white noise to reflect the random perturbations experienced during the evolution of the cold chain. A three-party stochastic evolutionary game model is established involving farmers, logistics enterprises, and government regulatory authorities. Based on this model, numerical simulation analysis is conducted to explore the effects of different factors such as the intensity of random disturbances and the loss transfer coefficient on the fluctuation of strategic choices of the entities and the convergence speed to a stable state during evolution. Finally, combining the results of numerical simulation, relevant policies and recommendations are proposed to provide insights and guidance for the development of cold chain logistics in agricultural products.

Urbanization and economic growth in China: empirical evidence based on a SIVQR approach

PurposeWe seek to quantify the relationship between urbanization and economic growth in China using recent advances in econometric techniques.Design/methodology/approachThis study adopts a smoothed instrumental variables quantile regression (SIVQR) estimator to obtain consistent estimates of the effects of urbanization on economic growth in China. Our approach accounts for the differential impacts of urbanization across the conditional distribution of economic growth while allowing for an identification strategy that addresses the endogeneity of urbanization. Our main findings reveal that ignoring urbanization endogeneity leads to inconsistent estimates of urbanization effects. Further, we find a positive relationship between urbanization and growth resembling an inverted U-shape. This supports the hypothesis that the beneficial effects of urbanization intensify at initial stages while diminishing beyond a certain threshold, due perhaps to weakening scale economies.FindingsOur main results indicate that the individual productivity gains brought by urbanization outweigh the negative effects thereof that impede productivity, thus contributing to the economic growth in China. Further, we find that ignoring differential impacts of urbanization underestimates the beneficial effects of urbanization for provinces whose quality of governance is in the vicinity of the center of quality distribution. Ignoring the endogeneity of urbanization generates inconsistent estimates of the elasticity of economic growth with respect to urbanization. Finally, we estimate an inverted U-shape resembling relationship between urbanization and growth.Research limitations/implicationsFirst, future studies would benefit from incorporating more data as provinces further east on the mainland become more urbanized and urbanization runs its course. Second, controlling the barriers to rural-urban mobility would contribute to the robustness of the estimated relationship between urbanization and growth once such data became available. Unveiling the impact of government-imposed barriers is key to designing optimal policies that help fuel economic growth in the country. Finally, future research could benefit from information on urbanization sources not considered here such as inter-provincial migration, as such data become publicly available.Practical implicationsQuantifying the beneficial effects of urbanization on economic growth can help guide the government in China to further fuel the growth through a set of relevant policy tools that promote urbanization.Social implicationsRural-urban migration in China lays the groundwork for economic advancement in recipient cities and economies, as it may induce scale economies. This can benefit both the economy at large and the migrants.Originality/valueThe SIVQR estimator accounts for potential heterogeneous effects of urbanization across the entire conditional distribution of growth while allowing for an identification strategy that addresses the endogeneity of urbanization. An additional distinguishing feature of the current study is our use of the most recent novel, provincial-level data obtained from the National Bureau of Statistics of China. Our focus on a single country allows sidestepping issues arising from the inconsistency of the definition of urban across different countries while accounting for intra-country urbanization drivers intrinsic to China, such as natural features and geographic characteristics. Therefore, our approach has the potential to sidestep the bias resulting from the differences in mechanisms behind urbanization-growth relationships across different countries.

This paper, based on the comprehensive audit practice in Ankang City, Shaanxi Province, summarizes the specific practices and achievements of Ankang, analyzes its role and the problems that exist. It studies from the perspective of effective governance how national audit at the rural level can promote effective rural governance and thus achieve rural revitalization; on this basis, it proposes relevant policy recommendations from clarifying the leading position of national audit at the rural level, audit subjects, audit forces, audit methods, and the application of audit results.

CONSUMER PROTECTION AND PUBLIC HEALTH

One of the objectives of the European Union is to ensure a high level of protection for its citizens, an objective that cannot be achieved without guaranteeing the protection of the health, safety and economic interests of consumers. In the context of these concerns, the European legislator has integrated consumer protection into all relevant policy areas of European Union legislation. The central aim of this policy is the protection of citizens' health, although the main responsibility in this direction rests with the Member States. Looking beyond the borders of the member states and even of the European Union, the Covid-19 pandemic has proven that health is a priority and goes beyond the area of interest, which is limited to the borders of a state or a union of states, but has gained global relevance.

Carbon capture and utilization under EU law: impermanent storage of CO2 in products and pre-combustion carbon capture

Abstract The evolving regulatory landscape within the European Union demonstrates a transition from prioritizing carbon capture and storage over carbon capture and utilization towards a more equitable treatment of both approaches in relevant legislation and policy frameworks. Nevertheless, the ‘permanence’ criterion of carbon dioxide in the products remains an ongoing challenge. Within the current European legal framework, harnessing the regulatory incentives depends on how long carbon dioxide remains in carbon capture and utilization products. The study elucidates the evolving regulatory landscape surrounding carbon capture and utilization by examining recent legislative initiatives and amendments to key directives such as the Emissions Trading System Directive and the Renewable Energy Directive. Furthermore, it explores the implications of the European Union Net-zero Industry Act and the Carbon Removal Certification Framework. In addition, this article examines and explains the need for expanding the scope of carbon capture and utilization and storage by incorporating pre-combustion carbon capture through methane splitting into the definition.

Does Farmers’ Cognition Enhance Their Enthusiasm for Adopting Sustainable Digital Agricultural Extension Services? Evidence from Rural China

The service model of digital agricultural technology extension, as a novel and sustainable approach, plays a pivotal role in facilitating the digital transformation of farmers’ agricultural practices. Leveraging survey data from 1475 farmers in China, the study employed a multivariate ordered logit model to investigate the relationship between farmers’ cognition and enthusiasm to adopt digital agricultural extension services. The findings revealed that subjective and objective cognitions positively influence farmers’ enthusiasm for adopting digital agricultural extension services. Furthermore, policy incentives, as a significant regulatory factor, effectively influence farmers’ cognition levels and enthusiasm to adopt digital agricultural extension services. Additionally, female respondents, farmers with higher educational levels, and membership in agricultural cooperatives all facilitate the adoption of these services. This study not only enriches the theoretical framework for agricultural technology promotion, aiding in the understanding of farmers’ decision-making processes when adopting digital agricultural extension services, but also provides a deeper insight into the role of digital agricultural technologies in promoting sustainable agricultural development, offering scientific evidence for relevant policy formulation and implementation.

Decomposition of China’s Carbon Emissions Responsibility from the Perspective of Technological Heterogeneity

A global agreement has been reached on the reduction in greenhouse gas emissions. Worldwide, countries have implemented measures to tackle carbon emission issues by establishing aggregate targets and decomposing responsibilities. This study aims to decompose carbon emissions by creating an input–output model that incorporates multivariate factors like energy consumption and water consumption, together with a ZSG-DEA (zero-sum data envelopment analysis) model considering technological heterogeneity (Tech-ZSG-DEA). Based on the total carbon emission data predicted using the STIRPAT (Stochastic Impacts by Regression on Population, Affluence, and Technology) model, the carbon emission efficiency of 30 provinces in China is evaluated according to multiple principles. This is achieved by considering variations in population, economy, energy consumption, and water consumption across different locations. The efficiency findings indicate a discrepancy between the initial allocation and the highest efficiency value of 1. The traditional ZSG-DEA model overlooks regional disparities and may worsen carbon emission pressures in less developed areas. In contrast, the Tech-ZSG-DEA model, which considers regional technological diversity, allows more efficient regions to help alleviate some of the carbon emission burden and considers economic and social benefits. There is a large difference in the emission responsibility of the provinces based on the different decomposition principles. Finally, relevant policy recommendations are provided, such as the formulation of differentiated and inclusively coordinated emission plans. In addition, there are also mechanisms for coordinating interests and joint prevention among different regions.

Effects of Wage Differentials, MFA, and GSP on Exports in the Bangladesh Textile and Garment Industry

ABSTRACT In this paper, we investigate the effect of inter-country wage differentials on textile and garment (T&G) exports of Bangladesh and present an account of the important issue of why textile and garment exports are directed from developing countries to developed countries. Our empirical results imply that the wage differentials between developed and developing countries constitute one of the main drivers of T&G exports. In addition, we checked other factors such as the Multi-Fiber Arrangement (MFA) and the Generalized System of Preferences (GSP) by including dummy variables representing the MFA quota withdrawal and the GSP. We found that removal of the MFA had a significant negative effect, as expected. Our study confirms the positive correlation between GSP and exports. After phasing out the MFA and its quota system, the wage differentials not only boost the T&G exports from Bangladesh, but also increase the effectiveness of GSP. Given such findings, we discuss relevant policy implications.

Evaluation and influencing factors of green transformation in three major urban agglomerations in China

Since the 21st century, the world has increasingly focused on the issue of sustainable development, and the green transformation issues have become a new hot topic worldwide. Green and low-carbon transformation has become an international consensus. Urban agglomerations are important connections between urban development and regional coordination, as well as important spatial carriers for economic activities. They are not only the main source of carbon emissions, but also the main battlefield for energy conservation and emission reduction. As an important field for carbon reduction, the green transformation of cities is crucial for achieving the “dual carbon” goals. This article focuses on 48 cities in the three most mature and influential urban agglomerations in China from 2011 to 2019, namely, the Beijing-Tianjin-Hebei urban agglomeration, the Yangtze River Delta urban agglomeration, and the Pearl River Delta urban agglomeration. The three-stage DEA model and Malmquist index model are used to measure the green transformation efficiency of the three urban agglomerations from both dynamic and static perspectives, and a Tobit regression model is constructed to explore the influencing factors of green transformation efficiency in urban agglomerations. Research has found that: 1) From a static perspective, the overall efficiency of green transformation in the three major urban agglomerations is at a high level, but from a temporal perspective, it shows a downward trend. The Pearl River Delta urban agglomeration is known for its green development, with the highest average efficiency of green transformation, followed by the Yangtze River Delta urban agglomeration. The Beijing-Tianjin-Hebei urban agglomeration has the lowest level of green transformation; 2) From a dynamic perspective, technological progress is the main driving factor for improving the efficiency of green transformation in the three major urban agglomerations. Therefore, the government should pay special attention to the progressiveness of technology when formulating relevant policies to promote urban green transformation; 3) From the perspective of spatiotemporal differences, there are significant differences in the spatiotemporal characteristics of green transformation among the three major urban agglomerations, and there are significant differences in green transformation strategies among different urban agglomerations. Eliminating environmental factors and random interference is necessary for accurately measuring the efficiency of green transformation in urban agglomerations; 4) From the perspective of influencing factors, factors such as industrial structure upgrading, green innovation level, and environmental regulation intensity jointly affect the efficiency of green transformation in urban agglomerations. Based on this, we should pay attention to the differences between urban agglomerations and implement policies tailored to local conditions; Strengthen the network system of urban agglomerations and avoid conflicts between cities; Encourage green technology innovation, accelerate industrial structure upgrading, and so on. This article focuses on the issue of green transformation in urban agglomerations, and conducts research from three perspectives: efficiency measurement, influencing factors, and implementation mechanisms. A relatively systematic theoretical framework for green transformation in urban agglomerations is formed, and an evaluation index system for green transformation efficiency in urban agglomerations is constructed and optimized. The composition mechanism of the five dimensional evaluation system for transformation efficiency is analyzed, and the bottleneck and breakthrough direction of the three major urban agglomerations in China in the development process are grasped. It has a good demonstration effect on the green transformation of other urban agglomerations.

Evaluation of decarbonization cost transfer: From transport to power sector in South Korea

To achieve net-zero emissions, major countries have implemented energy transition and electrification policies, incurring significant costs. Each sector, including generation, industry, transport, and buildings, has its own decarbonization strategy. However, as net-zero emission is a cross-sectoral issue, decarbonization efforts in one sector can impact others. In this study, we employed a combination of renewable energy adoption planning, battery electric vehicles (BEVs) charging pattern simulation, and electricity market modeling to evaluate the cost implications of transitioning to BEVs in the transport sector and its subsequent impact on the power generation sector. We considered long-term Korean policies for the power and transport sectors when constructing scenarios to compare transition costs. Our results indicate that, while the additional electricity demand from BEVs increases electricity system costs, utilizing nuclear power can significantly reduce these costs. The estimated cost of BEVs, totaling three billion US dollars, can be covered through the relevant transition policy in the power sector. However, nuclear power in Korea is only a temporary solution that delays the social costs of achieving net-zero emissions. Thus, the Korean government should develop alternatives for clean electricity. Our results also suggest that the decarbonization cost transition from a sector to the power sector should be considered in the net-zero policy.

The Impact of the Industrial Internet on the Innovation and Development Level of China’s Manufacturing Industry: Under the Perspective of Government Incentives

In the era of the digital economy, it has become an inevitable trend for manufacturing enterprises to establish industrial Internet platforms toward achieving transformation and innovative development. However, the current development model of industrial Internet platforms is still imperfect, wherein the application scenario is complex, the investment cost is too high, the return-on-investment cycle is too long, and other factors have hindered the willingness of manufacturing enterprises to employ cloud services and capital investment. For this reason, governments have introduced a series of relevant incentive policies to promote the development of industrial Internet platforms and the transformation and upgrading of manufacturing enterprises. Considering the role of government incentives, this study first constructs an evolutionary game model with local governments, manufacturing enterprises, and industrial Internet platforms as the main players. Then, the dynamic change process of each game player’s strategy choice and the stable state of the system evolution under multiple scenarios are analyzed, and the validity of the conclusions is verified through a numerical simulation analysis. Finally, the statistical data of 28 provinces in China from 2018 to 2020 are used to conduct an empirical test to explore the impact of the industrial Internet on the transformation and innovation development of the manufacturing industry and the role of government incentives. The results show that the development of the industrial Internet has a significant role in promoting the innovation and development of the manufacturing industry; government incentives can promote the innovation and development of the industrial Internet and manufacturing industry, but incentives should not be too generous; and the impact of developing the industrial Internet on the level of innovation input/output of the manufacturing industry shows obvious regional differences. This study takes the local government as an independent game participant into consideration, which enriches the research field of combining evolutionary game theory with the transformation and innovative development of the manufacturing industry. In addition, this study provides theoretical guidance and practical references for the government to formulate incentive policies to promote the development of industrial Internet platforms and for manufacturing enterprises to utilize these platforms to carry out innovation and perform upgrades.

Impact of the digital transformation of Chinese new energy vehicle enterprises on innovation performance

Digital transformation involves fundamental changes in business models, organizational structure, corporate culture, and even the way in which customers interact. Chinese new energy vehicle companies hope to achieve faster response speeds, greater operational efficiency, and better user experiences through digital transformation. Therefore, exploring how to successfully carry out digital transformation and its true impact on enterprise performance is of profound significance. The digital transformation of enterprises requires the embedding and absorption of network relationships to acquire and transform external resources and technologies, which further affects the innovation performance of these enterprises. This article introduces absorptive capacity as a mediating variable and network embeddedness as a moderating variable to construct a theoretical model, attempting to elucidate the mechanism of the impact of digital transformation on enterprise innovation performance. By combining theoretical and empirical analysis, the research hypotheses are tested, and the results show that 1. digital transformation (digital technology, digital products, and digital platforms) has a positive impact on enterprise innovation performance, 2. absorptive capacity plays a significant mediating role in the relationship between digital transformation and enterprise innovation performance, and 3. the embeddedness of network relationships has a significant positive moderating effect on the digital transformation of enterprises and their innovation performance. This article delves into an effective approach involving digital transformation, absorptive capacity, and enterprise innovation performance; analyses the moderating effect of network embeddedness; and concludes that the research findings have implications for the development of related research on digital transformation and enterprise innovation. The timely activities of enterprises to effectively carry out digital transformation, as well as the formulation of relevant policies, have positive significance.

Exploring the Relationship between Digital Inclusive Finance and Traditional Finance in China

Since 2016, China has incorporated the development of digital inclusive finance (DIF) into its national strategic plan and supported it with favorable policies. These policy changes not only promote the sustainable development of finance but also provide an opportunity to examine the relationship between DIF and traditional finance. This study utilizes panel data from China's prefecture-level cities spanning 2011 to 2019 and employs the generalized difference-in-difference method to analyze the impacts of relevant policies. The findings indicate a positive correlation between the level of traditional finance and the successful implementation of policies that promote DIF, suggesting a complementary relationship between traditional finance and DIF. Additionally, analysis reveals that in regions with more favorable financial and technological conditions, traditional finance plays a prominent supportive role in facilitating DIF. Therefore, policies promoting DIF should consider local financial and technological landscapes while developing tailored strategies based on the maturity level of traditional finance.

Unlocking the potential of rooftop solar panels: An incentive rate structure design

With the continuous maturity of distributed generation technology, rooftop solar panels have come to play an increasingly critical role in the construction of future energy systems. However, there remains an open question as to how to design adequate rate structure and provide proper incentives for distributed solar production. In this paper, we propose an incentive rate structure for rooftop solar panels to fairly unlock the potential of such distributed energy resources. The interaction of residential consumers and utilities is formulated as a tri-level optimization model to evaluate the impact of the rate structure design on the welfare transfer and investment behavior of residential consumers. An incentive rate structure is designed in which the supply-side effects of rooftop solar panel investment are considered by explicitly modeling wholesale market dynamics. Contrary to conventional belief, we indicate that the integration of rooftop solar panels can increase the expected profits of the utility company in some usual cases. Case studies demonstrate that through adequate rate structure design, the market operator can achieve the established social goals while balancing the welfare transfer effect among different market entities. Hopefully, our work can provide novel insights and a theoretical reference for the relevant policy design.

The Janus model of money demand

AbstractWe derive a new theoretical model of money demand, which reflects backward‐ and forward‐looking preferences in consumption and utility. The former aspect is captured by standard habit formation, and the latter by anticipation of future consumption preferences. By introducing both of these into the Ramsey–Sidrauski framework, we unveil a new highly general model of money demand. We discuss the model in light of the apparent breakdown of money‐demand functions and diminished policy relevance of monetary aggregates.

The relationship between preschool teachers’ sense of teaching efficacy and turnover intention during the COVID-19 pandemic: a mediation model

ABSTRACT During the COVID-19 pandemic period, preschool teachers experienced a hard time in which they were required to implement relevant epidemic prevention policies to ensure the health of young children, increasing their work engagement, work stress, and turnover intention. This study examined the relationship between Chinese preschool teachers’ sense of teaching efficacy and turnover intention based on the JD-R model, with work engagement and work stress serving as the mediators during the COVID-19 pandemic. Altogether 388 Chinese preschool teachers were recruited and surveyed online. The results indicated that (1) preschool teachers’ teaching efficacy was not associated with turnover intention directly; (2) preschool teachers’ teaching efficacy was associated with turnover intention indirectly through work engagement and work stress. These findings implied that preschool principals should take measures to improve preschool teachers’ teaching efficacy and work engagement, provide support to help them better cope with work stress, leading to decreased turnover intention, and getting through difficult times.

The influence and mechanism of female-headed households on household debt risk: empirical evidence from China

With the development of society, the number of female-headed households is on the rise. Based on the data from the China Household Finance Survey (CHFS) in 2019, this paper establishes a Tobit model to study the influence of female-headed households on household debt risk. Results indicate that female-headed households can substantially reduce household debt risk, and this conclusion still holds after overcoming endogeneity issues. Further tests on the mediating effect reveal that risk aversion and housing property holding have partial mediating effects and masking effects, respectively, in the path of female-headed households affecting household debt risk. In addition, the heterogeneity analysis indicates that the influence of female-headed households on household debt risk is more significant in third-tier cities, as well as in families without children, families without elderly members, and families with more than two elderly members. The conclusions of this paper provide a reference for the relevant policy measures to reduce household debt risk and promote gender equality.

Application of Renewable Energy in Green Buildings and Energy Consumption Optimization

INTRODUCTION: With the increasing global awareness of sustainable development and environmental protection, green building has become one of the important development directions in the construction industry. The application of sustainable type energy in the construction industry is of great significance in reducing building energy consumption and environmental pollution. This study aims to explore the application of sustainable types of energy and conduct research on energy consumption optimization. OBJECTIVE: The aim of this study is to analyze the current situation of the application of sustainable types of energy in the construction industry, to explore its impact on the energy consumption of buildings, and to propose corresponding optimization strategies in order to achieve the goal of sustainable development of green buildings in China. METHODS: This study adopts a combination of literature review and case study; firstly, a literature review on the application of sustainable types of energy, sorting out its technical characteristics and application effects; then, several typical cases are selected to analyze its energy application and energy consumption in buildings; finally, relevant strategies and suggestions for optimizing the energy consumption are put forward by combining the results of the literature review and the case study. RESULTS: Through the literature review and case analysis, it is found that sustainable types of energy, such as solar energy and wind energy, have been widely used in buildings and achieved certain energy-saving effects. However, there are also some problems, such as inefficient energy utilization and high cost. To address these problems, this study proposes a series of optimization strategies, including suggestions for optimizing energy system design, improving energy utilization efficiency, and reducing energy costs. CONCLUSION: This study concludes that the application of sustainable types of energy in green buildings is an important way to optimize building energy consumption and sustainable development. Through measures such as optimizing energy system design and improving energy utilization efficiency, building energy consumption can be further reduced, environmental pollution can be reduced, and the development of the construction industry can be promoted. However, further research and practice are still needed to continuously improve relevant technologies and policies to promote the application and development of sustainable types of energy in buildings.
