The development of digital financial inclusion has added a new vitality to economic growth, and environmental regulation is an important tool to achieve sustainable economic growth. Therefore, whether there is a synergistic effect between these two factors of economic growth is a topic worth exploring. This paper uses the space econometric model and threshold model to explore the impact of digital financial inclusion and environmental regulation on regional economic growth using panel data from 30 Chinese provinces, collected between 2011 and 2019. The research results prove that the development of digital financial inclusion and the improvement in the intensity of environmental regulation have a significant direct promotion effect and negative spatial spillover effect on regional economic growth. Moreover, the two have a significant synergistic effect on regional economic growth. A panel threshold analysis showed that, with the improvement in the level of digital financial inclusion, the regression coefficient of environmental regulation changed from negative to positive, which played a significant role in promoting regional economic growth. The heterogeneity analysis found that digital inclusive finance in eastern regions of China plays a greater role in promoting the economy, whereas environmental regulation in the central region plays a greater role in promoting the economy. The synergy between the two in the central region greatly promotes economic development. When digital inclusive finance is used as the threshold variable, environmental regulation in eastern and western regions has a single-threshold effect on regional economic development. Based upon these research results, this paper proposes that a coordination mechanism between digital financial inclusion and environmental regulation should be established to give full play to their synergies in sustainable economic growth.

Environmental regulation is a crucial tool for controlling environmental pollution. Digital finance is essential for the development of green finance. The relationship between environmental regulation and digital finance concerning environmental pollution is an issue worth exploring. This paper uses the spatial econometric model and the panel threshold model to empirically analyze the impact of environmental regulation and digital financial inclusion on environmental pollution using panel data from 30 Chinese provinces between 2011 and 2019. It mainly discusses the independent impact and synergy of environmental regulation and digital inclusive finance on environmental pollution. The research results show that the improvement of the intensity of environmental regulation and the development level of digital-inclusive finance can effectively alleviate the problem of environmental pollution. Moreover, environmental regulation and digital inclusive finance can coordinately control environmental pollution. A panel threshold analysis shows that as the intensity of environmental regulation increases, digital financial inclusion will reflect the function of environmental governance. Similarly, with the development of digital financial inclusion, environmental regulation has shown a significant inhibitory effect on environmental pollution. The results of a heterogeneity analysis show that the intensity of environmental regulation in the eastern region has a significant inhibitory effect on environmental pollution. Digital financial inclusion in the central region shows a strong environmental governance function. The intersection of environmental regulation and digital financial inclusion has shown a significant synergistic governance effect in the eastern region. Therefore, the government gives full play to the functions of environmental regulation and digital inclusive finance environmental governance to achieve coordinated governance of environmental pollution.

At present, coal enterprises generally have inadequate environmental protection, serious social issues, and poor corporate governance. Against the background of sustainable development strategies and the “carbon peaking” and “carbon neutrality” targets, there is an urgent need to conduct a performance evaluation of the sustainable development of coal enterprises. Environmental, social, and governance (ESG) performance is the foundation and booster of sustainable and high−quality development of coal enterprises. It is a typical application of sustainable development and performance evaluation theory to carry out ESG−led performance evaluation and case research of coal enterprises. Therefore, in this paper, we construct the model framework of ESG–grounded theory–entropy method–cloud model to research the performance evaluation of coal enterprises under the guidance of sustainable development from the dimensions of theoretical optimization and case analysis. The model framework includes the factor structure model, performance evaluation index system, index weighting model, and performance evaluation model. First, on the basis of the theory of ESG and triple bottom line, the finance–environment–society–governance (FESG) structural dimension model of coal enterprise performance evaluation was extracted through the three-level coding of grounded theory (GT). On this basis, the performance evaluation index system from the perspective of sustainable development was constructed. Second, on the basis of the entropy method (EM), the weight model of the coal enterprise performance evaluation index was constructed to determine the weight of indexes at all levels. Third, the performance evaluation model was constructed on the basis of the cloud model (CM), and the principles and methods of “dividing index grade, normalizing index grade, calculating index grade membership degree, and evaluating enterprise performance grade” were clarified. Fourth, in order to verify the feasibility of the model framework, a typical listed company (enterprise Z) in the coal industry was selected in order to conduct a case research based on the statistical data from 2016 to 2020 and analyze the performance grade evaluation results. The research shows that (1) the FESG structural dimension model extracted by grounded theory analysis method and the performance evaluation index system of coal enterprises oriented by sustainable development enrich the connotation and extension of ESG theory; (2) the index weighting model based on the entropy method can objectively determine the weight of indicators at all levels of each dimension of performance; (3) the construction path of coal enterprise performance evaluation model based on cloud model can be used to construct performance evaluation models for other industries; (4) the model framework based on the ESG–grounded theory–entropy method–cloud model can be used to reasonably measure the performance level of coal enterprises and provide theoretical support for the research of performance evaluation inside and outside the industry; (5) the sustainable development performance of coal enterprises is the basis and guarantee for achieving sustainable and high-quality development. The research results can provide theoretical reference for the regulatory authorities to formulate performance evaluation policies from the perspective of sustainable development.

The goal of public security and safety under the concept of sustainable development has been transformed into the maximization of the comprehensive goal of economic, environmental, and social security and safety. The polycentric collaborative governance mode is a crucial approach for the reform of government regulation. Social–ecological resilience has become a typical paradigm in the field of risk governance. Polycentric collaborative governance and safety resilience are the foundation and booster of elevator safety governance. In this paper, we expound on the system elements and mechanisms of polycentric collaborative governance and ecological resilience of elevator safety under the guidance of sustainable development by using a conceptual framework method. On this basis, we explore the influence degree and mechanism of elevator safety polycentric collaborative governance on elevator safety ecological resilience under the guidance of sustainable development by constructing a structural equation model based on micro-survey data. The results show that (1) the polycentric collaborative governance subject composed of the government, business, society, and the public is the key force to enhancing the ecological resilience of elevator safety; (2) enhancing the ecological resilience of elevator safety has a significant direct promoting effect on improving the mitigation, recovery, learning, and coping ability of elevator safety; (3) improving the learning ability has a significant direct promoting effect on improving the mitigation, recovery, and coping ability of elevator safety; (4) improving the coping ability has a significant direct promoting effect on improving the mitigation and recovery ability of elevator safety; (5) improving the mitigation ability has a significant direct promoting effect on improving the recovery ability of elevator safety. Therefore, in the process of elevator safety governance under the guidance of sustainable development, we should not only adhere to the polycentric collaborative governance mode but also attach importance to the ecological resilience governance paradigm of elevator safety, which together can improve the elevator quality and safety level.
