Green energy efficiency (GEE) is pivotal for sustainable economic growth, particularly in the context of China's ambitious environmental goals. This study assesses the impact of Green Financial Reform and Innovation Pilot Zones on GEE from 2005 to 2020, using the SBM-GML method and a Double Difference Model (DID). Findings indicate a significant improvement in GEE within these zones, driven by advancements in green innovation and environmental regulation. At the micro level, firms in pilot zones show enhanced Environmental, Social, and Governance (ESG) performance and experience fewer financial constraints. The effectiveness of green finance policies is more pronounced in resource-rich and financially efficient regions, suggesting that these initiatives can significantly contribute to sustainable development. Based on empirical evidence, we recommend expanding pilot zones, promoting green technological innovation, and developing tailored green finance policies to address regional ecological sensitivities.

Environmental protection and sustainable development are now profoundly ingrained in the public consciousness in the modern era of the global green revolution. First, this paper uses an evolutionary game model to theoretically analyse the impact of environmental regulation and green finance on enterprises by dissecting the game behaviour between local governments, banks and enterprises. Then, we incorporate entrepreneurial spirit into the model to determine whether entrepreneurial spirit accelerates the achievement of green sustainability objectives. Environmental regulation and green finance are found to contribute substantially to the innovation of green technologies by local enterprises, while entrepreneurial spirit accelerates this process. Finally, we empirically test the findings based on a prefecture-level panel dataset from 2007 to 2020. We find that green finance has a positive impact in Central and Western cities of China, while Eastern cities are in greater need for government environmental regulation controls. For entrepreneurial spirit, the incentive effect of entrepreneurial spirit on the level of green technology innovation is more significant in Central and Western regions of China. This paper enriches the field of research on entrepreneurial spirit and regional green sustainable development by providing empirical evidence for the evaluation of environmental regulatory and green financing policy impacts.

The escalating demand for resources in urban and rural construction development raises the crucial question of achieving green development within limited resource constraints. This study delves into the interplay between environmental policy and green development in urban and rural construction. Utilizing the spatial Durbin model for analysis, findings reveal that investment-oriented environmental regulation significantly impacts green development and positive spillover effects in neighboring regions when considering spatial weight matrices. In contrast, cost-based environmental regulations positively affect green development when spatial interactions are disregarded. However, they exhibit negative effects at the spatial level, potentially leading to a "pollution relocation" phenomenon. Although the influence of R& D subsidy-based environmental regulations on green development is not significant, their impact becomes notable upon considering spatial interactions, potentially generating positive effects across regions through mechanisms such as technology diffusion and knowledge transfer. Furthermore, from an endogeneity perspective, the impact of environmental regulatory tools on green development exhibits a time lag effect. Moreover, investment-type regulation in the eastern regions significantly fosters green development, whereas cost-based regulation shows a suppressive effect; investment-type regulation in central regions has a positive spillover on neighboring areas; and R&D subsidies in western regions negatively impact local green development. Moreover, the quality of governmental institutions, market integration, and technological innovation are key factors influencing green development in China's urban and rural construction. This study reveals the direct and indirect effects of various environmental policy tools on green development in urban and rural areas. It emphasizes the importance of considering spatial interactions in implementing environmental policies, providing a theoretical foundation and practical guidance for optimizing environmental policies.

This paper chooses 98 mining cities in China from 2007 to 2021 as research samples. It investigates the policy practice of green development in mining cities according to the point of view of policy combination. We establish a super-efficiency model considering undesirable output to measure the green development level of mining cities and further construct a dynamic panel model based on the Gaussian mixture model (GMM) to test the transmission mechanism and heterogeneous effect of different types of environmental regulation to promote the green development of mining cities. The findings demonstrate that environmental regulations about command control, market incentives, and public participation can all help mining cities develop more sustainably. Additionally, there is a nonlinear relationship of an inverted "U" shape between the degree of green development in mining cities and environmental regulations related to command control. Combining policies can encourage the green development of mining cities, but there are crowding-out and substitution effects when environmental regulations are combined with market forces. Environmental regulation promotes urban green development by improving the energy consumption structure of mining cities. In this process, the level of digital development positively regulates the impact of environmental regulation on urban green development. Therefore, the government should choose environmental regulation tools and combinations according to local needs to achieve a multi-pronged effect of energy structure improvement and urban green development and use digital technology to support the green development of mining cities. • Command-controlled, market-motivated, and public-participating environmental regulations can significantly promote urban green development by promoting the improvement of energy structure. • There is an inverted' U' -shaped nonlinear relationship between the intensity of command and control environmental regulation and the green level of mining cities. • The level of digitization can positively regulate the relationship between environmental regulation and urban green development. • The combination of environmental regulations have a significant positive impact on urban green development. • The combination of environmental regulations has heterogeneity in urban green development due to factors such as regional resource endowment.
