Abstract
This paper uses the super-efficiency SBM model to measure the green economic efficiency considering undesired output and analyzes the spatial distribution difference of green economic efficiency; secondly, the nonlinear panel threshold model is used to empirically study the nonlinear relationship between environmental regulations and green economic efficiency, and further analyzed the threshold effect of environmental regulations on the efficiency of green economy and concluded as follows. (1) The green economy efficiency index in the eastern region is mostly more significant than 1, and the green economy efficiency in most provinces in the eastern region has improved. These provinces have higher regional production levels and less environmental pollution. The green economy efficiency of the central region is second only to the eastern region. The green economy efficiency of provinces in the western region except Chongqing is less than 1, indicating that these provinces have insufficient regional production, severe environmental pollution, or extensive resource depletion. (2) The impact of environmental regulations on the efficiency of the green economy presents an inverted “U” shape, with a threshold of 0.5128 for environmental regulations. The impact of the industrial structure on the efficiency of the green economy changes from inhibition to promotion after crossing the threshold of the intensity of environmental regulation, and the degree of opening to the outside world has a complementary effect on the efficiency of the green economy. The impact of urbanization on the efficiency of the green economy changes from promotion to suppression after surpassing the threshold of the intensity of environmental regulations.
Highlights
After the industrial revolution, with the development of heavy chemical industries, more and more resource constraints and environmental pollution problems began to emerge
We must adhere to the vital concept of the green economy. e report of the 19th National Congress of the Communist Party of China pointed out that it is necessary to establish the concept of a green economy and at the same time establish a long-term mechanism for environmental management and control in order to achieve a win-win situation for economic development and environmental protection. e long-term consumption of resources and energy and the deterioration of the ecological environment have been the price of rapid economic growth, and the conversion rate of input to output in the green economy is low [3]
The term “green economy efficiency”, which has evolved from the concept of “green development” and is highly representative, has increasingly become a hot topic for scholars. e efficiency of the green economy is different from the traditional economy that ignores resources and environmental costs
Summary
With the development of heavy chemical industries, more and more resource constraints and environmental pollution problems began to emerge. E report of the 19th National Congress of the Communist Party of China pointed out that it is necessary to establish the concept of a green economy and at the same time establish a long-term mechanism for environmental management and control in order to achieve a win-win situation for economic development and environmental protection. As there is still considerable controversy on this issue, this article intends to conduct an empirical analysis, using panel data from 30 provinces (municipalities and autonomous regions) in China to test whether the impact of environmental regulations on green economy efficiency is promoted or inhibited? Since the implementation of environmental regulation policies may have a lag effect, this article will use environmental regulation as the core explanatory variable to construct a panel model that includes the quadratic term of environmental regulation to test the nonlinear impact of environmental regulation on the efficiency green economy. Considering that the implementation of environmental regulation policies is likely to have nonlinear characteristics in the impact of green economy efficiency, this paper uses the square term of environmental regulation to test the nonlinear relationship between environmental regulation and green economy efficiency, which is a valuable supplement to existing research
