Discussion On Environmental Regulation And Total Factor Productivity Of Automobile Industry From The Perspective Of Regional Heterogeneity

With the continuous development of modern society,environmental resources play an important role in economic development.Environmental resources have the characteristics of public goods and scarcity.When environmental pollution reaches a certain limit,it will have an inestimable impact on society and the economy.The automobile industry is a capital-intensive industry and also occupies an important position in China’s industrial industry.At the same time,the automobile industry has close relations with other industries,such as the steel industry,rubber industry,etc.,so the development of the automobile industry has a great impact on the development of the national economy.However,the automobile industry,as a traditional industry,it will encounter environmental pollution problems rapid development.For example,the exhaust gas emitted by automobiles is likely to cause air pollution and reduce people’s quality of life.Therefore,in order to improve environmental pollution,environmental regulations are particularly important.With the gradual improvement of China’s environmental regulatory system,it will inevitably affect the production efficiency of enterprises.This research is based on the "Porter Hypothesis" principle,from the perspective of the role of environmental regulation on the total factor productivity of automobile companies as a research perspective,and analyzes its mechanism from a micro level.The mechanism of environmental protection and sustainable economic development can not only provide valuable reference for academic circles,but also have practical significance.This research will use empirical models to explore the effects of environmental regulation on auto companies efficiency and the impact of regional heterogeneity.The total factor productivity of each auto company will be expressed by measuring the company’s Hicks – Moorsteen index using data from listed companies.Based on the availability and analysis of the research data,this paper uses the data of 64 listed auto companies to analyze the TFP index and its decomposition index of the automobile industry in detail,andempirically explores the intensity of environmental regulations and TFP and The relationship between its decomposing factors,the research results show that there is a clear non-linear correlation between environmental regulation and the total factor productivity index and its decomposition index,but looking at its subregions,the total factor productivity index and the environmental regulation index are in coastal areas and within There are different correlations in continental regions.The second section of the article explains the theoretical basis and hypotheses of this research.The third section will explain the calculation method of Hicks – Moorsteen index and its analysis results.The fourth section will introduce the regression model and variables of the paper.The five subsections are research results and robustness analysis,and the sixth subsection is policy recommendations.
