| Promoting high-quality economic growth is an inevitable requirement of economic laws.In order to cope with the severe environmental protection situation and improve the quality of economic growth,the government’s environmental regulation on enterprises has been increasingly strengthened.Environmental regulation will have an impact on the environment and improve the quality of the environment,on the other hand,it will have an impact on economic growth.There has been more and more discussion on the issue of environmental regulation in the academic community.The research focuses on the debate on "innovation compensation theory" and "following cost theory,in the "Porter hypothesis" and the number of economic regulation and environmental innovation.Research on speed and environmental regulation have less research on the quality of economic growth.China’s economy has shifted from a high-speed growth stage to a high-quality development stage.Therefore,it is necessary to study the effects of environmental regulation and technological innovation on the quality of economic growth.First of all,this paper defines the concepts of economic growth quality,environmental regulation and technological innovation by combing relevant literature.And review the discussion of this problem in the existing literature,after the literature review,put forward the research questions of this paper.Secondly,it analyzes the impact mechanism of environmental regulation and technological innovation on the quality of economic growth.Specifically,this article demonstrates the impact of environmental regulations on the five dimensions of efficient economic growth,advanced industrial structure,stable economic development,rational use of resources,improved welfare,and fair distribution.And the impact of technological innovation on economic growth efficiency,industrial structure upgrade,and rational use of resources.It also analyzes the synergy between the impact of environmental regulations and technological innovation on the quality of economic growth.On the basis of theoretical review and demonstration,this paper establishes a data index system and conducts an empirical test.In the empirical research part,this paper uses the balance panel data of 29 provinces in China from 2000 to 2016 as the research sample this paper and establishes an empirical model to examine the impact of environmental regulation and technological innovation on the quality of economic growth,and the role of technological iunovation as a threshold variable in it.The fixed effect model,the system GMM model,and the panel threshold model were established for empirical testing,and the robustness test was passed.From a national perspective,environmental regulation can signifieantly promote the quality of economic growth.From different perspectives,there are different differences;technological innovation has significantly promoted the quality of economic growth.Under the constraints of environnental regulation,the role of technological innovation in promoting the quality of economic growth will be reduced;the impact of environmental regulation on the quality of economic growth has a "threshold effect",and environmental regulation can significantly promote economic growth quality after crossing the threshold of self-improvement and technological innovation.Finally,based on the conclusions of the empirical analysis of this paper,the corresponding policy recommendations are put forward.The government should continue to implement environmental regulation policies,but it is necessary to adapt to local conditions and avoid "one size fits all".In addition,enterprises and scientific research institutions should be encouraged to carry out technological innovation and develop environmentally friendly production technologies. |
