An Empirical Study On The Impact Of Low-carbon Pilot Policies On Technological Innovation

Lucid waters and lush mountains are invaluable assests.The ecological problem has become a problem that the whole world must face directly.Since the 18 th National Congress of the Communist Party of China,the Chinese government has made many reforms and measures for the ecological environment,among which the low-carbon pilot policy is one.The National Development and Reform Commission said that all regions implementing the low-carbon pilot policy should effectively promote the R&D and industrialization of low-carbon technology,and actively apply low-carbon technology to transform and upgrade local traditional industries.Therefore,building a low-carbon pilot city is to improve the level of local technological innovation.This paper hopes to add theoretical evidence for low-carbon pilot policies by studying whether low-carbon pilot policies have significant impact on technological innovation,and provide a solid basis for better implementation of low-carbon pilot policies nationwide.As the first batch of pilot cities involved in provincial data is inconvenient to compare,and the technological innovation index of the third batch of pilot cities has not yet been published,this paper selects the second batch of pilot cities from the three batches of low-carbon pilot cities,and analyzes the panel data of 211 cities in China from 2006 to 2016.The precondition of using the double difference model is to satisfy the parallel trend test,that is,to satisfy the randomness of policy implementation time.The innovation points of this paper are as follows:(1)study the impact of low-carbon pilot and technological innovation on the one hand of environmental regulation;(2)use innovation index instead of traditional indicators to measure innovation.The content of this paper is as follows: first,using the dual difference model to study whether the low-carbon pilot policy has an impact on technological innovation;Second,the robustness test is carried out on the basis of the processed data,and the reliability of the regression results is further verified by modifying the following data:(1)redefining the interpreted variables;(2)excluding the influence of extreme values;(3)excluding the influence of other policies;(4)PSM-DID;(5)counterfactual test;The third is to test the heterogeneity of national data,respectively from the following three dimensions to explore the impact of low-carbon pilot policies on Technological Innovation: city size,spatial location,city type.Among them,there are three types of city scale in this paper: small city,big city and mega city;three types of spatial location: eastern city,central city and western city;two types of city: resource-based city and non resource-based city;The fourth is to use the intermediary effect model to study the impact mechanism and path of low-carbon pilot policies on technological innovation.The empirical results show that the low-carbon pilot policy has a significant positive effect on technological innovation,and the city size,spatial location and city type have different degrees of impact on the implementation of the policy.For big cities,western cities and resource-based cities,the low-carbon pilot policy will not promote technological innovation,but will hinder technological innovation.Finally,the intermediary effect model shows that the mechanism of low-carbon pilot policies affecting technological innovation is through influencing the number of scientific and technological talents,industrial structure and financial R & D investment.Therefore,local governments can increase the number of scientific and technological talents,adjust and optimize the industrial structure,and increase the financial investment in R & D to enhance the impact on technological innovation,which lays a solid foundation for the full implementation of low-carbon policy in China and provides a strong reference.
