Research On Green Total Factor Productivity Of Northeast Equipment Manufacturing Industry From The Perspective Of Heterogeneous Environmental Regulation

It can be seen from the traditional modern economic growth theory that economic growth cannot be separated from the influence of institutions,and the resource and environment institutions often have a great influence on the green total factor productivity and further act on the economic growth.Therefore,on the basis of traditional related research theories,this paper starts with environmental regulation itself,takes it as an important institutional factor affecting GTFP,and further studies the mechanism of environmental regulation’s effect on GTFP in Northeast equipment manufacturing industry through the principle of the two effects.Combined with the super efficiency SBM model and DEA-Malmquist index analysis model,the green total factor productivity of equipment manufacturing industry is calculated from the static and dynamic analysis perspectives,and then the environmental regulation is divided into three categories through the establishment of Tobit model.The paper also empirically analyzes and tests the relationship between the three environmental regulations and the green total factor productivity of Northeast China.The findings:(1)From the perspective of Northeast China as a whole,the main factor affecting the GTFP growth of equipment manufacturing industry is technological progress;The main factor affecting the change of comprehensive technical efficiency is pure technical efficiency.The main reason for the ineffectiveness of comprehensive efficiency is that scale efficiency is ineffective.(2)Compared with other provinces,the comprehensive efficiency and its two decomposition items of Jilin Province are the highest;While Heilongjiang Province saw the fastest growth of GTFP among the three provinces,technological progress was the main factor leading to this result.(3)From the data,the growth of GTFP in 4 of the 7 industries,the growth ranked the first is the special equipment industry,the second is the instrument and cultural industry,the third is the general industry,the fourth is communication and other electronic equipment industry,the change of technological progress is the main reason;Among the 7 industries,there are two industries with the highest comprehensive efficiency,and the inefficiency of pure technical efficiency leads to the inefficiency of comprehensive efficiency,while there is one industry with the lowest comprehensive efficiency,whose inefficiency is mainly caused by the inefficiency of scale efficiency.(4)The empirical results of Liaoning Province and Heilongjiang Province verify the Porter Hypothesis theory of this paper.The empirical results of these two provinces show that public voluntary and market incentive environmental regulations are more suitable for Liaoning Province and Heilongjiang Province,while the empirical results of Jilin Province show an inverted "U" shaped relationship.In Liaoning Province,except the industrial structure has a negative effect on GTFP,the other control variables have a positive effect.The industrial structure of Jilin Province has a positive effect in the command-control environment and the public participation environment,and the other control variables have a positive effect in the market incentive environment.The degree of opening to the outside world of Heilongjiang Province has a positive effect on GTFP,while the others have a negative effect.Suggestions are put forward through empirical conclusions,and further evidence is provided for Porter Hypothesis theory in this paper.
