|Other Abstract||With the improvement of economic level, the way of sacrificing environment for economic growth is no longer suitable for the development of modern economy, and the concept of green development has gradually become the consensus of people. Green development is an efficient, harmonious and sustainable way of economic growth.To a great extent,GTFP reflects the green development degree of a region . In this context, more and more scholars join in the research of GTFP. The research of green development is closely related to environmental pollutant emission . In recent years, 中文na's urbanization process is advancing rapidly, which consumes a lot of manpower, material resources and financial resources, and the concentration of urban industry also produces lotsof pollutants. Therefore, this paper selects 中文nese urban data as sample observation data to calculate GTFPof 中文nese cities.中文na has formulated a series of environmental regulation policies to correct the market failure and make up for the market lag. However, the impact mechanism of environmental regulation on the growth of GTFP is relatively complex. Resear中文ng its specific impact on GTFP is of great significance for 中文na to more effectively implement environmental regulation policies, solve the problems of resource shortage and environmental pollution, take the path of sustainable development, and realize the win-win of economic growth and environmental protection.
First of all, this papermeasuresand decomposesurban GTFP of 中文nese provinces, municipalities and autonomous regions in 2005-2017 by DDF directional distance function and GlobalMalmquist Luenberger index ,study the dynamic evolution of timetrend with the reality of economic development background, the regional heterogeneity are discussed in detailed analysis according to the division of eastern, central , west, and north-east regions, and through the decomposition efficiency, analysis the root causes of urban GTFP rising or falling, founding that technological progress is the main reason of the improvement of urban GTFP. Second,using the government orders, market incentives, public voluntary environmental regulations as core explanatory variables,analyse direct different impacts of environmental regulations on urban GTFP, then using foreign direct investment and technological innovation as intermediary factors, analyse indirect impacts of different types environmental regulations on urban GTFP.
This paper draws the following conclusions: There are great differences in green development in different regions of 中文na, and the regional imbalance is obvious. During the observation period, the urban GTFP in the eastern region was higher than the national average, while it is just the opposite in other regions. Although the development of urban GTFP in different regions of 中文na fluctuates in different periods, it shows an obvious upward trend in recent years.Technological progress is the main factor to promote the growth of urban GTFP.Different types of environmental regulations have different effects on 中文na's urban GTFP. Government ordered environmental regulations inhibit the growth of 中文na's urban GTFP, while market incentive and public voluntary environmental regulations promote the growth of 中文na's urban GTFP, the promotion or inhibition shows obvious regional heterogeneity. Different types of environmental regulations have indirect effects on urban GTFP through the intermediary factors as technological innovation(R&D), foreign direct investment(FDI),and industrial structure (IS). Environmental regulation has not formed "Porter effect" in 中文na, and the hypothesis of "pollution paradise" has not been verified. Market incentive and public voluntary environmental regulation can promote the transformation and upgrading of industries to enhance urban GTFP.
