| With the rapid development of economic society,ecological and environmental issues have become a common challenge facing human society.In order to improve the ecological environment and promote green transformation and development,China has made major work arrangements of "carbon peak" and "carbon neutral".As a major policy innovation to reduce greenhouse gas emissions and promote green and lowcarbon development,carbon emissions trading is an important environmental policy tool to achieve carbon peak,carbon neutral,and the purpose of its formulation is to assist the development of low-carbon and clean industries and stimulate the motivation of green innovation in enterprises,Transform traditional production methods to achieve industrial structure upgrading and achieve emission reduction targets.In the transitional period of China’s economic development,upgrading the industrial structure is the only way to achieve carbon emission reduction and sustainable development.Therefore,in this context,it is of great significance to explore the impact of carbon emissions trading policies and green innovation on the upgrading of industrial structure.Based on a review of relevant literature and theories,this article analyzes the relationship and mechanism of carbon emissions trading policies,green innovation,and industrial structure upgrading.It selects panel data from 30 provinces(cities,districts)from 2005 to 2020 as research samples to empirically analyze the direct and indirect impacts of carbon emissions trading policies on industrial structure upgrading.The study finds that:(1)Carbon emission trading policies have a significant promoting effect on the upgrading and rationalization of the industrial structure.Moreover,the promotion effect of carbon emissions trading policies on the upgrading of industrial structure is greater than its promotion effect on the rationalization of industrial structure.(2)There is regional heterogeneity in the impact of carbon emissions trading policies on industrial structure upgrading.The carbon emission trading policy can promote the upgrading of the industrial structure in the eastern region,but has no effect on the central and western regions;The carbon emission trading policy has no significant effect on the rationalization of the industrial structure in the eastern region,but has a significant positive effect on the central and western regions.(3)Carbon emission trading policies can promote the upgrading of industrial structure through green innovation.There is an inherent mechanism for green innovation in the impact of carbon emissions trading policies on industrial structure upgrading.Based on the above study conclusions,this article,proceeding from reality,proposes the following policy recommendations to further promote the establishment of a carbon emissions trading market,stimulate the momentum of green innovation,and promote the upgrading of industrial structure: First,it is necessary to improve the carbon emissions trading market mechanism,and promote the mature development of the national carbon emissions trading market;Secondly,improve the level of green innovation,give play to the dynamic role of innovation in the upgrading of industrial structure,and promote the optimization and upgrading of industrial structure;Finally,the government should increase policy incentives,play a policy guiding role,and promote green innovation in enterprises. |
