Study On The Impact Of Environmental Regulation On Green Total Factor Productivity

Since modern times,with the advancement of industrialization and urbanization,the global ecological environment has been seriously damaged.While China's economy is growing rapidly,it also pays a painful economic and environmental cost for environmental pollution every year.With the gradual transformation of China's economy from a high-speed growth stage to a high-quality development stage,in order to implement the concept of green development,various regions have adopted reasonable and effective environmental measures and issued relevant policy standards to improve the ecological protection system,reduce environmental pollution,prevent ecological deterioration,and promote the coordinated development of environment and economy.Therefore,from the perspective of environmental regulation,this paper deeply explores the impact of environmental regulation on green total factor productivity,which has important theoretical and practical significance for promoting the convergence of environmental regulation policy with the green economy of various regions,improving economic quality and accelerating economic transformation and upgrading.This paper analyses the current situation of environmental regulation in China,and uses ML index based on non-radial and non-angular SBM model to calculate the green total factor productivity of China's provinces.The results show that from 2001 to 2016,China's total green factor productivity shows an overall growth trend,and the average green factor productivity in the eastern coastal areas is basically larger than that in the central and western inland areas.In the theoretical analysis,environmental regulation is classified,and the direct effect of environmental regulation and the indirect effect of environmental regulation based on technological innovation and foreign direct investment are analyzed from both positive and negative perspectives,and the impact of environmental regulation on green total factor productivity is sorted out.On this basis,this paper uses the panel data of 30 provinces in China from 2001 to 2016 to build an econometric model,and uses the system GMM method to explore the impact of three different types of environmental regulation on green total factor productivity at the national and subregional levels.The main conclusions of this paper are as follows:At the national level,the impact of different types of environmental regulation on green total factor productivity is quite different.There is an inverted U-shaped curve between command-controlled,voluntary-conscious environmental regulation and green total factor productivity,while the effect of market-motivated environmental regulation on green total factor productivity is a U-shaped curve.From the regional level,the incentive effect of command-control environmental regulation on green total factor productivity in eastern coastal areas is not obvious,while market-incentive environmental regulation and voluntary environmental regulation directly show a positive linear role in promoting green total factor productivity.The influence of command-controlled and voluntary environmental regulation on green TFP in the inland areas of China and the West presents an inverted U-shaped curve,while the influence of market-motivated environmental regulation on green TFP is linear and positive.Finally,this paper puts forward relevant policy suggestions from four aspects:reasonable collocation of different types of environmental regulation,implementation of regional differentiated environmental policy,optimization of environmental regulation and technological innovation combination,and strengthening strict screening of environmental regulation for foreign direct investment.
