Environmental Quality Optimization of Sustainable Rural Revitalization Strategy Based on Improved Genetic Algorithm

To address the environmental quality of sustainable rural revitalization strategies, an improved genetic algorithm-based approach is proposed, environmental quality of rural revitalization strategies. Firstly, an index system to comprehensively assess the settlement environment of rural people based on the “production-production-production” space is built and then forms the trinity theoretical guidance framework; secondly, value of information entropy used to evaluate the dispersion of an index calculates the weight of each indicator and provides the basis for a comprehensive multi-index assessment; thirdly, by analyzing the spatial differences of rural human settlement environment quality, the quality of human settlement in rural areas has a positive correlation with the level of regional economic development. It shows that based on improved genetic algorithm, the environmental quality of sustainable rural revitalization strategy has been greatly improved, the growth rate of the comprehensive score of rural living environment in most regions reached more than 14%, and the comprehensive score growth rate of some rural living environment was 4.52%.

Economic Growth Effect of Public Health Investment and Its Impact on Living Environment.

Based on the concern of Chinese residents for health and the improvement of related service demand, this paper studies the economic growth effect of public health investment and its impact on living environment by analyzing the determination coefficient estimated by Spearman and nonlinear curve. The results show that the impact of increasing government financial public health investment on regional economic growth rate is not only related to regional economic aggregate and development level, but also related to regional education level and regional publicity level in logical analysis. The improvement of residents' living environment brought by public infrastructure investment can effectively stimulate residents' concept of health consumption and then make the economy of nonpublic health undertakings achieve a higher growth rate. The economic growth rate brought by nonpublic health undertakings is also an important component of the local economic growth rate. It can be seen that strengthening the infrastructure construction of urban living environment can not only improve the overall living environment quality of the city, but also promote the development of the city and the development speed of the city.

Regional innovation ability and its inequality: Measurements and dynamic decomposition

To bridge the research gap regarding the inequality of innovation ability, this paper proposes a more reasonable proxy indicator of research and development capital, applying the concentration index to quantify the inequality of regional innovation ability based on the regional economic levels in China and to dynamically decompose changes of regional innovation ability inequality. The study reveals that China's innovation ability has gradually improved, accompanied by significant regional agglomeration effects and widening regional gaps. The findings indicate that inequality of regional innovation ability in China remains high, and the correlation between the regional innovation ability and economic development level has increased. Improvement in the degree of synergy between regional economic development is conducive to alleviating the inequality of regional innovation ability, and cumulative innovation ability effects, particularly the scale factor, exacerbate the inequality of regional innovation ability. This research has important practical significance for policymakers and researchers seeking approaches to investigate and promote effective the coordinated development of regional innovation and improve the overall quality and efficiency of innovation ability.

Can Environmental Regulation Reduce Urban Haze Concentration from the Perspective of China’s Five Urban Agglomerations?

Based on the perspective of urban agglomerations, this paper explores the impact mechanism of environmental regulation on haze, and tries to find the most suitable environmental regulation intensity for haze control in urban agglomerations. This paper uses the fixed-effect model and panel threshold model to verify the effect of environmental regulations on haze concentration in 206 cities in China. A grouping test is also conducted to verify whether a regional heterogeneity arises due to different regional development levels for five urban agglomerations and non-five urban agglomerations, respectively. The results show that: (1) In the linear model, strengthening environmental regulation can reduce the haze concentration, but this effect is not significant. The effect of environmental regulation on haze control in the five major urban agglomerations is better than that in the non-five major urban agglomerations; (2) In the nonlinear model, the impact of environmental regulation on haze shows a “U” trend in the five major urban agglomerations and an inverted “U” trend in the non-five major urban agglomerations. Although the results are not significant, we can still conclude that the impact of environmental regulation on haze varies depending on the level of regional economic development. Therefore, the environmental regulation should be formulated according to local conditions; (3) In the threshold model, the impact of environmental regulation on the haze concentration in five major urban agglomerations has a threshold effect. In the five major urban agglomerations, although environmental regulation can effectively reduce haze concentration, the governance effect will weaken as the environmental regulation increases. This study plays a positive role in guiding local governments to adjust environmental regulation intensity according to local conditions and helping local environmental improvement.

Evaluation of the Coupled and Coordinated Relationship between Agricultural Modernization and Regional Economic Development under the Rural Revitalization Strategy

Agriculture is one of the three major industries in China, and its level of development occupies an important position in the development of the national economy. At present, China vigorously promotes the strategy of rural revitalization, which provides new opportunities for agricultural modernization. Since modern agriculture and regional economy are coupled in a mutually influencing and constraining relationship, this paper constructs a coupled and coordinated evaluation index system of agricultural modernization and regional economic development. Using the entropy value method and coupled coordination degree model, the comprehensive development level and coordinated development degree of agricultural modernization and regional economic development of 31 provinces, autonomous regions, and cities in China from 2011 to 2020 were evaluated, revealing the time evolution and spatial distribution characteristics of the two systems. The results show that: (1) In the past decade, China’s agricultural modernization and regional economy have made some progress in terms of their respective development levels and the degree of coupling and coordination between them. (2) In terms of spatial evolution, there are obvious regional differences between the two systems, and the coupling coordination degree shows a “ladder” distribution pattern from the east to the central, northeastern, and western parts of the country. (3) Regions with a high level of regional economic development also have a relatively high degree of coupling and coordination between agricultural modernization and regional economic development. Our results provide insights into the economic effects of agricultural modernization in China and provide useful insights into the future direction of agricultural development programs in countries around the world.

Environmental tax reform and environmental investment: A quasi-natural experiment based on China's Environmental Protection Tax Law

Using a 2015–2019 sample of Shanghai and Shenzhen A-share listed companies and the difference-in-differences method, this paper analyzes the effect of the implementation of China's environmental tax in 2018 on firms' environmental investments. The results show a significant increase in firms' environmental investments after the implementation of the tax. Further analyses examine variations in the effect according to ownership type, regional economic development level, and media attention. The positive effect is more significant for state-owned companies and companies subject to high media attention, but there is no obvious difference between companies in regions with different levels of economic development. Additional analysis reveals that government subsidies negatively affect firms' environmental investments, but the environmental tax reduces such subsidies and thus their inhibitory effect, increasing firms' environmental investments. Additionally, the results show that the environmental tax promotes firms' performance by increasing their environmental investments. This paper provides theoretical support and empirical evidence for the implementation and improvement of the environmental tax policy.

Moderating effects of regional disparities on the relationship between individual determinants and public health service utilization among internal migrants: evidence from the China migrant dynamic survey in 2017

BackgroundRegional disparities and individual determinants have a significant impact on the accessibility of national essential public health services (NEPHS) for internal migrants (IMs) Nevertheless, few studies have explored the interaction between these two factors.MethodA cross-sectional sample of 102,632 IMs from the 2017 China Migrant Dynamic Survey was selected. The 28 provinces were divided into high-income provinces (HIPs) and low and middle-income provinces (LMIPs) according to their per capita disposable income (PCDI). Logistic regression was conducted using sex, residence duration, education, community type, migration range, social participation and relative personal income as independent variables, NEPHS awareness and health records registration (HRR) as dependent variables, and regional economic development level (REDL) as a moderating variable.ResultsThe rate of NEPHS awareness and HRR in HIPs (60.7, 30.6%) were lower (x2 = 42.486, p < 0.001; x2 = 25.573, p < 0.001) than those in LMIPs (62.9, 32.2%). After controlling for other variables, NEPHS awareness (OR = 1.379, p < 0.001) and HRR (OR = 1.661, p < 0.001) of IMs in HIPs were higher. Sub-group proportion of education Ms. in HIPs were higher. Sub-group = 1.379, p < 0.001) and HRR dependent mong internal migrants:, 61.0, 42.2%) were higher than those in LMIPs (60.4, 19.7, 35.8, 25.5%). Among urban communities, intra-provincial migration, social participation, education > 9 years, and middle-income, the protective effect of the first three factors on NEPHS awareness was greater in HIPs (OR = 1.386, p < 0.001; OR = 1.383, p < 0.001; OR = 2.008, p < 0.001) than in LMIPs (OR = 1.053, p < 0.001; OR = 1.109, p < 0.001; OR = 1.861, p < 0.001), while the effect of all five factors on HRR was greater in HIPs (OR = 1.440, p < 0.001; OR = 1.380, p < 0.001; OR = 1.895, p < 0.001; OR = 1.148, p < 0.001; OR = 1.146, p < 0.001) than in LMIPs (OR = 1.045, p < 0.05; OR = 1.169, p < 0.001; OR = 1.677, p < 0.001; OR = 1.027, p > 0.05; OR = 1.028, p > 0.05).ConclusionsREDL directly affected the NEPHS utilization of IMs, and the negative effects of vulnerable characteristics on the NEPHS utilization of IMs were amplified in HIPs. The government is urged to regard IMs with vulnerable characteristics in HIPs as the key population in future NEPHS equalization and take targeted measures to stimulate their enthusiasm to participate in NEPHS.

Has environmental policy improved the job quality of migrant workers? A quasi-natural experiment on China's Clean Air Action

Whether China's Clean Air Action can be imperative to job quality improvement of labour force while improving environmental quality is still an ongoing research topic. It is a critical area to understand the economic and social effect of environmental policy under the strategic goal of high-quality economic development. We use China's “Clean Air Action” policy as a quasi-natural experiment to identify the causal effect and potential long-run impact of the environmental policy on internal migrant workers' job quality. Based on the difference-in-difference estimation and a series of robustness tests, such as PSM-DID, counterfactual framework, placebo test, and event study, we find that China's Clean Air Action does have a positive effect on the job quality of migrant workers, and the job quality of the migrants in the Clean Air Action sampling cities increased by 0.31 on an average compared with cities that did not implement Clean Air Action. This positive effect will increase over time, and with the level of regional economic development and urban scale rise. Moreover, the job quality improvement could be driven by the productivity effect and the positive adjustment of labor force employment structure from action. This study provides an important empirical evidence for directions of this new action. Our results suggest that further policy measures with a clear goal together with strong-oriented and sub-regional joint governance mechanisms over different levels of government are called for.

Comparative Analysis of Locational Factors and Their External Influence on Free-Trade Port Zones in China

In the context of regional economic integration, free-trade port zones (FTPZs) have become a powerful platform for attracting high-quality international investment and promoting national economic development. It is worthwhile, then, to explore the hidden value of the locational factors of FTPZs in the process of their construction. Specifically, analyzing the key locational factors of FTPZs and their influences on the locational value can help to improve the ability of FTPZs to add value through factor congregation and further promote the development of regional economies. This study, therefore, analyzes the locational factors of the Shanghai and Ningbo-Zhoushan free-trade ports using an econometric model. The corresponding external influences of locational factors are examined as well. The results show that regional economic development level, industrial structure, port and shipping system, capital accumulation, talent quality, institutional policies, market scale, market consumption potential, and market openness are the essential factors affecting the locational value of FTPZs. Based on our analysis and comparison of the location characteristics and locational value of the Shanghai and Ningbo-Zhoushan free-trade ports, three constructive suggestions are made to enhance the locational value of free-trade ports based on the actual situation of the Ningbo-Zhoushan free-trade port. These suggestions can also maximize the value of free-trade ports’ locations and promote high-quality regional economic growth.

Research on the impact of green finance and abundance of natural resources on China's regional eco-efficiency

This article uses the Super-efficiency DEA mothod to calculate the regional ecological efficiency, and selects a Tobit model to verify the impact of green finance and natural resource abundance on Chinese regional ecological efficiency. Results as follows: (1) The ecological efficiency of the eastern region is highest, and western region is lowest. Most of the low-efficiency areas are concentrated in the west. Then the ecological efficiency of most areas in Chian has shown an increasing trend. (2) From the perspective of explanatory variables, there is a negative correlation between the overall national green finance and eco-efficiency, which is manifested in a non-linear “U”-shaped characteristic; green finance and eco-efficiency in the central and western regions have negative correlation and “U”-shaped characteristic of non-linear relationship, but the east of China does not passed the significance test. (3) There is an inverted U-shaped relationship between the country's overall resource abundance and ecological efficiency. And it is not statistically significant in the eastern region, but it shows a significant inverted U-shaped relationship in the central and west of China. (4) The impact of FDI on China's regional eco-efficiency is generally positive. FDI in the central and western regions has negative correlation with eco-efficiency, but FDI in the eastern region is positively related to eco-efficiency; there are all negatively correlated in whole countey and regions between industrial structure and eco-efficiency; the level of regional economic development is generally positively related to regional eco-efficiency, and in the eastern region's eco-efficiency is positive, and the impact on the other two regions is negative.

The role of economic development on the effectiveness of industrial pollution reduction policy in Chinese cities

The societal impact of industrial pollution produced by economic activities is a global concern. This paper presents a causal analytic framework to evaluate the effectiveness of government policy on the reduction of industrial pollutants in 284 Chinese cities between 2005 and 2016. This study reports on the interaction between industrial pollution reduction and the level of regional economic development from four dimensions by using analysis of variance (ANOVA),multivariate analysis of variance (MANOVA) and a bootstrap autoregressive-distributed lag (ARDL) test. The results indicate that city government policies, economic power, the influence of megacities, and the geographical region of the cities have significant effects on industrial pollution, in particular, sulfur dioxide (SO2) emission reduction and dust reduction. After taking account of the interaction effect of city government policies and the other three factors, it was found that economic power is the only factor to have a significant interaction with city government policies on industrial pollution reduction. The ARDL test found long-term causality among industrial pollution reduction, fixed assets investment, and GDP per-capita in city, urban agglomeration, and regional levels. This study sheds new light on the relationship between regional economic development and the development of sustainable societies.

Calculation of regional agricultural production efficiency and empirical analysis of its influencing factors-based on DEA-CCR model and Tobit model

The improvement of agricultural production efficiency and the transformation of production mode are the core of promoting agricultural modernization. Taking Chongqing as a sample case, this paper uses DEA-CCR Model, Malmquist Index and Tobit Model to calculate and analyze its agricultural production efficiency and its influencing factors, and accurately identifies the problems existing in its agricultural transformation and development. It has an important policy reference value for improving agricultural innovation and competitiveness, promoting the steady development of rural revitalization, and realizing agricultural modernization, which also provides some reference and enlightenment for countries or regions with similar characteristics of mountain agriculture development in the world to enhance regional agricultural production efficiency. Through empirical analysis and investigation, it is found that the overall agricultural production efficiency of Chongqing remains at the productivity level of 0.8 from 2009 to 2018, with an average annual growth rate of 12.8%, but there is a large gap in the level of regional development. Through Malmquist Index decomposition, it is found that agricultural technology progress has the greatest contribution to the improvement of production efficiency. Financial support for agriculture, urbanization level, regional economic development level and highway mileage have a significant positive impact on production efficiency, while the level of farmers’ disposable income has a negative impact on the increase of production efficiency, and the income gap between urban and rural residents fails to pass the significance test.

The Patterns and Mechanisms of Land Price Divergence in Multiple Industries from the Perspective of Element Flows: The Case of the Yangtze River Delta, China

An in-depth exploration of the inner mechanisms of the spatio-temporal evolution of land prices in multiple industries (residential, commercial service and industrial) is of great significance for improving the overall economic development efficiency and resource allocation capacity of the region. Based on urban land price transaction data provided by the China Land Market Network, 307 county-level units in the Yangtze River Delta were used as the study area and spatial auto-correlation and spatio-temporal hotspot analysis were used to explore the spatial variation and temporal changes of land prices in multiple industries in the Yangtze River Delta from 2008 to 2018. The three-dimensional driving theory of land “demand + supply + market” was used as the basis to construct the index system of influential factors and the Spatial Durbin Model was used to explore the mechanism of the spatio-temporal variation of land prices in multiple industries. The results show that the land prices of multiple industries in the Yangtze River Delta are generally high in the east and low in the west and high in the south and low in the north, which is spatially consistent with the level of regional economic development. Due to the disparity in economic development between the regions, factors such as population, capital, technology and information are redistributed and fed into each other’s cycles between cities. The resulting spatial differences in land market supply and demand are intrinsic to the spatial differentiation of urban land prices. It is further proposed that land prices are a monetized expression of the abundance of resources in a city and that land prices are determined by the combined ability of regional resource factors to be allocated. Thus, land price differentiation reflects differences in the level of comprehensive regional development. Finally, the dynamic interaction of various factors on land values is used to promote the division of urban functions and regional economic development, which is an effective way to promote high-quality integrated regional development.

A research on measure of regional agricultural economic development level based on Entropy-CRITIC method and K-Means

The continuous promotion of China's rural revitalization strategy has not put forward higher requirements for the development of overall agriculture. However, it is difficult to regulate the status quo of unbalanced regional economic development. Based on this, this paper selects the provinces and cities in Sichuan Province from 2018-2020 as the research object and constructs a regional agricultural economic development level index system, and then uses the entropy value CRITIC method to assign weights and carry out linear weighting to obtain the regional agricultural economic development level index from the consideration of the volatility and conflict of data. Then, K-Mean clustering was used to analyze the level of agricultural economic development in Sichuan Province from two dimensions: geographical and temporal. The empirical results show that: from the time dimension, the comprehensive index of high-quality agricultural economic development in most regions shows a trend of increasing year by year since 2018-2020; from the geographical dimension, it shows the form of strong in the north and weak in the south, and strong in the center and weak in the fourth. Finally, this paper puts forward relevant suggestions for the development of regional agricultural economy in conjunction with the actual situation.

The impact of heterogeneous environmental regulations on the technology innovation of urban green energy: a study based on the panel threshold model

&lt;abstract&gt; &lt;p&gt;Since the Porter hypothesis was proposed, environmental regulation has been recognized as a critical factor influencing technology innovation. However, there is no unified conclusion on whether the relationship between the two is linear or non-linear, and environmental regulation is always examined from single angles. Therefore, according to the difference of environmental regulation implementation subjects, this paper divides environmental regulation into formal regulation and informal regulation. Utilizing the panel data of 281 prefecture-level and above cities in China from 2011-2019, the non-linear effects of heterogeneous environmental regulations on green energy technology innovation are analyzed based on the panel threshold model, and the non-linear relationship between the two under the difference in urban economic development level is further considered. The results indicate that: (1) The threshold effect of the environmental regulations on China's green energy technology innovation is significant, and there is heterogeneity in the effects of different environmental regulations. (2) At present, positive relationship are observed between the informal environmental regulation and green energy technology innovation in China, while the formal environmental regulation exerts a significant inhibitory effect on green energy technology innovation. (3) The level of regional economic development plays a significantly positive role in moderating the relationship between environmental regulation and green energy innovation. However, there exists a certain heterogeneity in the moderating role between the formal regulation-innovation link and informal regulation-innovation relationship. This study provides a reference for further clarifying the relationship between heterogeneous environmental regulations and green energy technology innovation.&lt;/p&gt; &lt;/abstract&gt;

Research on the Impact Evaluation of Digital Finance on the Synergy between Economic Development and Ecological Environment.

Following rapid growth, China's economy is entering a period of high-quality economic growth. High-quality economic development has a profound impact on China's current economic development. It can be said that the improvement of economic quality is an inevitable choice for China's new stage of economic development. From this point of view, promoting high-quality economic development has become an important practical issue in my country's current economic and social development. As the integration and innovation of digital technology and taxation, the blessing of digital technology maximizes integration and precision, which can effectively meet the needs of higher stages of economic development. Perfect and inclusive development has become an important support for sustainable and healthy economic development. At present, behind the rapid economic growth, human economic activities have led to the emergence of an ecological and environmental crisis. The growth mode characterized by high input, high consumption support, and high emissions has resulted in insufficient supply of regional ecological and environmental resources, pollution, and damage to the ecological environment and also intensified. Therefore, this paper first examines the concept of digital finance and its enlightenment to economic development, and believes that digital finance has a good role in promoting economic development. Second, an evaluation model for the relationship between environmental environment and economic development is established, and an evaluation index system is obtained. Finally, through the comprehensive evaluation and analysis of economic development and ecological environment, it is concluded that in the era of digital finance, the level of regional economic development has been greatly improved, and my country's regional economic development has been greatly improved, which is significantly faster than my country's ecological environment improvement level.

Digital Transformation, Regional Economic Development and High-quality Development of the Logistics Industry—— An Evidence from China

Promoting high-quality development of the logistics industry is an important way to smooth domestic circulation in the new development pattern of "double circulation". Based on the data of China's A-share logistics listed companies from 2007 to 2021, this paper empirically studies how digital transformation can promote the high-quality development of the logistics industry. The results show that digital transformation promotes the high-quality development of the logistics industry by improving self-development and distribution mechanism; The level of regional economic development will significantly adjust the role of digital transformation in promoting the high-quality development of the logistics industry; Big data technology, cloud computing technology and digital technology application are the main digital transformation channels to promote the high-quality development of the logistics industry.

Financing Efficiency Evaluation and Influencing Factors of Hydrogen Energy Listed Enterprises in China

Existing studies of financing efficiency concentrate on capital structure and a single external environment or internal management characteristic. Few of the studies include the internal and external financing environments at the same time for hydrogen energy industry financing efficiency. This paper used the data envelopment analysis (DEA) model and the Malmquist index to measure the financing efficiency of 70 hydrogen energy listed enterprises in China from 2014 to 2020 from both static and dynamic perspectives. Then, a tobit model was constructed to explore the influence of external environment and internal factors on the financing efficiency. The contributions of this paper are studying the internal and external financing environments, and integrating financing cost efficiency and capital allocation efficiency into the financing efficiency of hydrogen energy enterprises. The results show that, firstly, the financing efficiency of China’s hydrogen energy listed enterprises showed an upward trend during the years 2014–2020. Secondly, China’s hydrogen energy enterprises mainly gather in the eastern coastal areas, and their financing efficiency is more than that in western areas. Thirdly, the regional economic development level, enterprise scale, financing structure, capital utilization efficiency and profitability have significant effects on the financing efficiency. These results can promote the achievement of “carbon neutrality” in China.

Analysis of the Coupling Coordination and Spatiotemporal Evolution of High‐Tech Industrial Technological Innovation and Regional Economic Development

Improving the coordination between technological innovation in high‐tech industries and regional economic development is an important measure for all provinces (cities) to implement the innovation‐driven development strategy. Based on the analysis of the mechanism of high‐tech industrial technological innovation and regional economic development, this paper constructs the measurement index system of high‐tech industrial technological innovation and regional economic development, and the chain network DEA model, entropy weight method, coupling coordination model, and exploratory spatial data analysis technology are comprehensively used to empirically analyze the technological innovation efficiency of high‐tech industries, regional economic development level, and the coupling coordination relationship between them and the spatiotemporal evolution trend in 24 provinces (cities) of China from 2009 to 2018. The results show that (1) there are significant differences in the average level of technological innovation efficiency of high‐tech industry in each stage, which is the most prominent in the technology research and development stage, followed by the industrialization stage, and finally in the technology transformation stage. (2) The degree of coupling and coordination between high‐tech industrial technological innovation and regional economic development is increasing year by year, which is in the adaptation stage of high‐tech industrial technological innovation and regional economic development. (3) From the perspective of spatial pattern, there is a positive spatial autocorrelation between the coupling coordination degree of high‐tech industrial technological innovation and regional economic development. The number of provinces (cities) with low coupling coordination degree is much larger than that with high coupling coordination degree, showing a serious imbalance of regional heterogeneity and forming two spatial aggregation areas of “high‐high” diffusion effect and “low‐low” low‐speed growth.
