Land Supply Strategy,industrial Structure Upgrading And Environmental Pollution

Since economic reform and open up,China’s economy has continued to expand rapidly,with an average annual growth rate of about 9%.However,while we have achieved remarkable results,we are also facing serious problems such as excessive use of resources,environmental pollution and ecological destruction.Among them,environmental pollution has an important impact on the sustainable development of China’s economy and even social stability.In order to remove the root cause for this problem,people’s attention has also shifted from environmental pollution itself to various causes of environmental pollution,which can help achieve the coordinated development of national economy and ecological environment.As one of the basic production factors,land is an important carrier of industrial development,which plays a supporting role in industrial development;and the development of industrial structure is closely related to environmental pollution.Therefore,starting from the basic elements of land,we do research on the relationship between land supply strategy and environmental pollution in conjunction with the upgrading of the industrial structure,which will help us better understand the causes of environmental pollution.At first,this article introduces resource allocation theory,urban land competitive rent theory,industrial structure optimization theory,and externalities theory.Secondly,this paper uses data statistics to analyze present situation of China’s land supply strategy,the upgrading of industrial structure and the status of environmental pollution.Combined with existing research,we card the impact mechanism of land supply strategy on environmental pollution.Then,based on the panel data in 99 large and medium-sized cities from 2008 to 2017 and mediation effect models,this paper makes an empirical analysis of environmental pollution and the Scissors difference of commercial land,residential land and industrial land.The study found: First,the differential supply strategy of high-priced commercial and residential land and low-priced industrial land has an inverted U-shaped impact on the upgrading of industrial structure;the upgrading of industrial structure help optimize resource allocation and reduce environmental pollution.Second,the direct impact of land supply strategy on environmental pollution is U-shaped.That is to say,a reasonable price ratio is helpful to improve the ecological environment,and excessive "distortion" of the price ratio between commercial and residential land and industrial land will lead to mismatch of land resources,and increase environmental pollution.Third,the indirect impact of land supply strategy on environmental pollution is U-shaped.The land supply strategy will affect the upgrading of the industrial structure and then the ecological environment.When the Scissors difference of commercial and residential land(CR_Land)and industrial land is within a reasonable range,it will help upgrade the industrial structure,and reduce environmental pollution;while beyond a certain range,it will cause land resources to tend to industry,make the industrial structure rigid and inhibite the upgrading of the industrial structure,and eventually aggravate environmental pollution.Fourth,there is regional heterogeneity that land supply strategy affect environmental pollution.Compared with the eastern region,the implementation of land supply strategy in the central and western regions has a greater and more significant impact on environmental pollution.Based on the above research conclusions,this article puts forward relevant policy recommendations.Firstly,we will further advance the reform of the land transfer mechanism and optimize the efficiency of land resource allocation.Secondly,we could use the market mechanism to optimize the industrial layout and improve related policies to stimulate technological innovation.Third,each region should adapt to local conditions,and establish a reasonable and effective price comparison mechanism.Forth,local government should raise awareness of environmental protection and build a strong and effective environmental regulatory system.
