| With the rapid development of the economy,China’s environmental pollution and resource consumption have become increasingly severe.In order to solve the increasingly severe environmental pollution and resource lack of resource,the Chinese government has continuously improved environmental laws and regulations,complete the relevant theoretical system,and the construction of China’s ecological civilization has achieved positive progress in the past decades.Green investment is an indispensable ring that solves environmental pollution issues,and improving green investment efficiency is an important means of environmental pollution problems and better resolution.The implementation of government environmental regulations is increasingly stringent,and heavy pollution companies have increasing green investments in such a context,strengthen pollution control,but the governance effect is not very good.Therefore,it is necessary to study the relationship between environmental regulation and corporate green investment efficiency.A large number of research demonstrates the promotion of technological innovation to green investment efficiency,so it is necessary to study the impact of technological innovation on the relationship between environmental regulation and green investment efficiency.This thesis is based on the real situation of China’s environmental regulation,corporate green investment,and corporate environmental pollution,which combines the combination of empirical and case analysis,qualitative and quantitative analysis,and introduces the research significance of the article from two aspects of theory and reality.Studying environmental regulations and green investment efficiency relationships,helping to provide some suggestions on the improvement of green investment efficiency,optimize enterprise environmental protection investment fund configuration.Second,on the basis of reference related literatures,it is based on sustainable development theory,Podote,and polluting paradise fake,the relationship between environmental regulation,technological innovation and corporate green investment efficiency makes assumptions.Then,based on 2017-2019 China A-share heavy pollution industry listed company invested output data,measure the efficiency of enterprise green investment,and establishes the relationship between the TOBIT model empirical analysis environmental regulation and the efficiency of green investment efficiency,and introduced Technical innovation is used as an intermediary variable,and the impact of technological innovation in environmental regulation and corporate green investment efficiency.By analyzing the relationship between environmental regulation,SH company technology innovation and its green investment efficiency,the relationship between environmental regulation,SH technology innovation and its green investment efficiency.Finally,the conclusions of the paper provide some policy recommendations to improve the green investment efficiency of enterprises.Reflecting the shortcomings in the study,and possess in the future research.The specific research conclusions of this paper are as follows:(1)Environmental regulation has a significant forward effect on enterprise green investment efficiency;(2)Environmental regulation has a significant forward role in technological innovation,technological innovation has a significant positive direction for enterprise green investment efficiency Role,technological innovation has an intermediary effect in environmental regulation and corporate green investment efficiency. |
