Abstract
Haze pollution is a problem that cannot be ignored in the process of building sustainable cities, and while shifting industrial enterprises can solve the problem at the root, it is not conducive to the sustainable development of urban economies. This paper discusses the role of industrial agglomeration on urban pollution amelioration (haze pollution) using a sample of 253 prefecture-level cities in China. The highlight of this paper is the study of economic and environmental factors in the development of sustainable cities in the same framework and a series of econometric treatments that greatly increase the accuracy of the empirical evidence. Research intuitively shows that China’s haze pollution is clustered in spatial distribution and is spatially heterogeneous in concentration. With the passage of time, haze pollution has a tendency to move from an H–H concentration area to an L–L concentration area. The regression results show that an increase in the scale of local industrial agglomeration will lead to a decrease in local haze pollution; but an increase in the scale of local industrial agglomeration will lead to an increase in haze pollution in adjacent areas. Industrial agglomeration has significant spatial spillover effects, which are spatially heterogeneous. In addition, spillover effects between regions are greater than those within regions. After replacing the spatial weight matrix and controlling the endogenous problem using the instrumental variable method, the conclusion is still robust.
Highlights
Sustainable development is the theme of economic development in the world today.In Our Common Future, sustainable development was first defined as “development that meets the needs of the present without compromising the ability of future generations to meet their needs”
A clear correlation can be found between the level of industrial agglomeration in cities and their level of economic development
We found that the coefficient of IA is always negatively significant at the 1% level when the control variables are gradually added, suggesting that industrial agglomeration suppresses the level of local haze pollution
Summary
Sustainable development is the theme of economic development in the world today.In Our Common Future, sustainable development was first defined as “development that meets the needs of the present without compromising the ability of future generations to meet their needs”. In the rapid development of more than 20 years, the new type of economy represented by China has always paid attention to the expansion of “quantity” but ignored the improvement of “quality” [2]. This crude economic development method has promoted China’s economic take-off on the one hand [3], but on the other hand, it has led to increasingly serious environmental pollution problems in China and reduced the quality of economic development [4], which is not conducive to the long-term stable and sustainable development of China’s economy [5]. Industrial enterprises are the backbone of many cities, such as: the revitalization strategy of the old industrial base in Northeast China [6,7], the strategy of China’s western
