Environmental Regulation and China's Green Total Factor Productivities: Based on the Perspective of Vertical Specialization

In the process of Chinese enterprises participating in international vertical specialization,the polluted task may be transferred from the developed countries to China.But few scholars have analyzed whether environmental regulation could affect green total factor productivity(TFP) based on the perspective of new international division of labor.In order to analyze this issue,this paper measures green TFP in Chinese 27 manufacturing industries from 2002 to 2010 by applying the Slacks-based Measured(SBM) approach,and examines the influence of environmental regulation intensity on green TFP of manufacturing enterprises when they were involved in the process of international vertical specialization,and at last we test the industry disparity of environmental regulation intensity on green TFP.The results show that:①there is a U-type relationship between the intensity of environmental regulation and manufacturing green TFP on the whole,which means the initial weaker intensity of environmental regulation weakens green TFP,however,with the increase of intensity of environmental regulation,the rate of green TFP gradually increases;②there is a certain difference of the impact of environmental regulation on green TFP between cleaning departments in pollution intensive departments.Therefore,moderately increasing the intensity of environmental regulation and adopting various flexible methods of environmental regulation can not only protect the environment,but also promote technical innovation and enhance China's manufacturing enterprises' green TFP.
