As a measuring tool of industrial sustainable development, industrial eco-efficiency works as a link between economic benefit and environmental pressure. Industrial agglomeration and energy have always been considered an important influence factor on industrial eco-efficiency. The Chinese government is facing the challenge of reaching a Carbon Peak by the 2060s, within this context, it is critically important to explore the relationship between industrial agglomeration and industrial eco-efficiency, moreover, energy intensity may play a key role between them, which should not be ignored. Therefore, based on the STIRPAT model, this paper constructs a spatial autocorrelation model (SAC model) to analyze the provincial panel dataset from 2009 to 2018, and it is found that: First, the industrial agglomeration has an inverted N-shaped relationship with industrial eco-efficiency, and industrial eco-efficiency indeed have a positive spatial spillover effect. Second, energy intensity plays a mediating role, industrial agglomeration would affect industrial eco-efficiency through energy intensity. Therefore, it is suggested that the government should introduce differentiated industrial agglomeration policies as well as energy-saving policies. In addition, this paper suggests that policymakers should adhere to consistent industrial sustainable development policies.

This paper uses technological innovation as a mediating variable, based on 30 provincial panel data in China from 2011 to 2019, and uses the spatial Durbin model to study the spatial effect of green finance on PM2.5. It is found that the development of green finance not only inhibits local PM2.5 emissions, but also drives the development of green finance in the surrounding areas through the spillover effect of green finance, thereby inhibiting PM2.5 emissions in the surrounding areas. Through empirical research, this paper also finds that technological innovation has a significant mediating effect on the reduction of PM2.5 by green finance. At the key stage of green transformation in China, green finance can optimize the allocation of financial resources and provide financial support for technological innovation of enterprises, thereby reducing energy consumption and pollution emissions through technological innovation and ultimately inhibiting PM2.5. This study links green finance and PM2.5 from the perspective of space, and explores the channels to improve air quality in China, which is conducive to accelerating the green transformation of China 's economy and improving the human living environment.
