| Since the reform and opening up,the economic stock and residents’ income have increased rapidly,but also accompanied by the increasingly serious ecological deterioration.Therefore,promoting green and clean production and controlling carbon emissions have become an important task in the 14 th five year plan.Cement industry has always been a highly polluting industry,so it has become the main target of environmental protection policies With the continuous increase of environmental regulation,the pollution discharge cost of the cement industry is increasing,and the environmental protection access threshold is becoming higher and higher.It is in the "bottleneck period" of sustainable development.Only by carrying out green innovation can the cement industry break free from the shackles of environmental regulation,However,how to guide the green innovation of cement enterprises and how to carry out green innovation have become urgent problems to be solved.Therefore,it is very important to explore the impact mechanism of policy tools on green innovation in cement industry,build an appropriate policy combination and encourage cement enterprises to actively and spontaneously carry out green transformation and upgrading.Combined with regulation theory,externality theory,Porter hypothesis,rent-seeking theory and research literature at home and abroad,this thesis brings environmental regulation,government R&D subsidy and enterprise green innovation into the same logical framework from the perspective of policy synergy and complementarity.Then,taking CONCH as the further research object,using the specific case of CONCH green innovation to analyze the impact path of environmental regulation and Government R&D subsidy on cement enterprises’ green innovation,from the environmental regulation and Government R&D subsidy faced by CONCH,This thesis analyzes that CONCH’s green innovation is driven by environmental regulation and compensation,as well as the incentive effect of Government R&D subsidy,as well as the synergistic effect formed by environmental regulation and Government R&D subsidy,that is,with the enhancement of environmental regulation intensity and Government R&D subsidy,The higher the enthusiasm of CONCH to carry out green innovation;When the Government R&D subsidy is large,it can enhance the promotion effect of environmental regulation and weaken the crowding out effect of environmental regulation,which is conducive to give full play to the incentive effect of environmental regulation on Green Innovation of CONCH.Finally,the case analysis summarizes the conclusion that environmental regulation and Government R&D subsidies play a positive role in promoting the green innovation of CONCH,and the successful experience of how to grasp the policy dividend and break through the restriction of environmental regulation through green innovation.And draws some enlightenment on how to speed up the green transformation of cement enterprises through green innovation.At the policy level,the government needs to further improve the regulatory policy,give play to the guiding role of R&D subsidy policy,and build a reasonable combination of policy tools;At the enterprise level,enterprises need to increase investment in green innovation,change ideas and take the initiative to carry out green innovation. |
