| In today’s rapid economic development,people are gradually aware of the importance of solving the environmental pollution problem.China,as a responsible country,has put forward various policies to actively participate in environmental protection,among which carbon emissions trading,as an important part of the composition of the emission rights policy,the state attaches great importance to it,green water and green mountains are golden mountains,and the implementation of a good carbon emissions trading policy is very important for the state to manage the environment and establish confidence in managing the environment well.As a mandatory policy is the most effective means to limit environmental pollution,we not only want to clarify the mechanism of its role in limiting environmental pollution,but also want to understand how it will affect the regional economic development.Industrial agglomeration represents a high concentration of capital in a certain industry in a certain region.For a region,the change of industrial agglomeration has a profound impact on the regional economic development,and is an important basis for the government to formulate relevant regional policies and is the basis of regional industrial development.Therefore,this paper hopes to provide theoretical evidence for policy implementation by studying the impact of carbon emissions trading policy on industrial agglomeration,so as to better formulate relevant policies according to regional differences and industry differences,and better play the role of carbon emissions trading policy.This paper takes the carbon emissions trading pilot policy as the policy evaluation object to study the impact of carbon emissions trading policy on industrial agglomeration.A panel data model is constructed using sub-regional data from2006-2018.In order to more precisely derive the impact brought by the policy,a triple difference model and a double difference model with fixed year,region,and industry effects are used to empirically investigate the impact brought by the implementation of the carbon emissions trading policy from three perspectives: the degree of regional industrial specialization,the degree of spatial agglomeration of industries,and the spatial distribution balance of industries,respectively.In the short term,the carbon emissions trading policy may lead to the transfer of enterprises with lower carbon emissions to regions with higher environmental standards,while enterprises with higher carbon emissions will face two choices: one is to transfer to regions with lower environmental standards,and the other is to continue to produce in regions with higher environmental standards due to the higher cost of transfer and the formation of a certain scale of economic ecology in the region.In the other case,due to the high cost of transfer and the formation of a certain scale of economic ecology in the region,companies may choose to continue their production activities in the region with higher environmental standards.The empirical evidence shows that the carbon emissions trading policy obviously promotes the industrial agglomeration of the affected industries in the pilot region,and although the carbon emissions trading policy has a "pollution refuge" and "barrier to entry" effect on some enterprises,it also promotes the industrial agglomeration of the region due to enterprise innovation.The impact of carbon emissions trading policy on industrial agglomeration of different regions and industries is different due to the regional economic differences and different policy conditions,and the impact of the policy on industrial agglomeration of different regions and industries is different.This paper illustrates the impact of carbon emissions trading policies on industrial agglomeration from both national and regional perspectives.The results show that the impact of carbon emissions trading policies on industrial agglomeration is positive in both national and regional perspectives,i.e.,the implementation of the policies will promote industrial agglomeration.This paper has important implications for expanding the implementation of carbon emissions trading policy and rationalizing the regional industrial structure. |
