In the development of electric vehicle industry,how to make effective use of industrial policies to coordinate the development of electric vehicles and charging piles is a policy problem faced by the government.At present,the number of electric vehicles in China has jumped to the top in the world,but the pile ratio is lower than that in developed countries.The lagging development of charging infrastructure has inhibited the development of electric vehicles in China.The development of charging infrastructure in China lags behind the development of new energy vehicles for a long time.The main reason is that the charging infrastructure industry lacks a viable profit model,and the industry lacks clear and direct financial support policy,which leads to its operational difficulties and long-term loss.Relevant data show that by the end of 2017,the number of new energy vehicles in China is about 17.229 million,and the number of public charging piles is about 213,900.The ratio of piles is about 8:1,which is far from meeting the normal charging demand.Although provinces have introduced relevant policies,the promotion effect is far below expectations.On this basis,this paper studies the effect of industrial policies on charging infrastructure,and provides reference for the formulation and revision of relevant policies.This paper mainly explores the impact of industrial policy on the development of new energy vehicle charging infrastructure from both theoretical and empirical aspects.In theory,through a large number of literature research,understand the domestic and foreign industrial policies and charging infrastructure research results.On this basis,the transmission mechanism of industrial policy is sorted out,which lays a theoretical foundation for the empirical analysis in the following part.Empirically,through systematically sorting out and subdividing the relevant industrial policies,the industrial policies are subdivided into planning policies,preferential tariff policies,land policies and subsidy policies.The subsidy policy is further divided into two categories: power subsidy and total investment subsidy.The impact of different industrial policies on the development of new energy vehicle charging infrastructure is studied.Based on the monthly data at the provincial level from 2015 to 2018,this paper uses DID method to evaluate the impact of various industrial policies on the development of charging infrastructure.The research shows that the subsidy policy has a significant promotion effect on charging infrastructure,and the subsidy policy based on investment amount is better than the subsidy policy based on power to some extent.However,preferential tariff policy,land policy and planning policy have no obvious effect on charging infrastructure.Regardless of the high level of development of charging infrastructure,or the low level of development of charging infrastructure,the policy has a significant positive role in promoting.The government should scientifically determine the scale and layout of the construction according to the actual situation.When formulating the policy,the government should give priority to the incentive mode of subsidy according to the amount of investment,explore more effective subsidy mode to assist the preferential policy of electricity tariff,refine the land policy to ensure that the layout of charging infrastructure can be implemented.At the same time,it also needs to recommend strengthening regional exchanges and cooperation and sharing development experience.Improve the level of regional coordination management.There are two main contributions of this paper: First,we try to explore the impact of industrial policies on charging infrastructure.There are few studies on this aspect in the existing literature,and the literature on charging infrastructure mainly focuses on planning layout and demand forecasting.This paper enriches the research results in this field to a certain extent.Secondly,the industrial policy is systematically sorted out and subdivided.By comparing the impact of different policies on charging infrastructure and the difference of impact intensity,more practical suggestions can be provided for the formulation and revision of the policy.But there are also some shortcomings in this paper.First,the data is limited,which affects the empirical results.Because of the late start of the charging infrastructure industry,the available sample size is limited.If the sample size is larger,the conclusion will be more convincing.Secondly,the selection of control variables is not comprehensive enough.There are many related factors,but based on the data,this paper only adopts some indicators.If the selection of control variables is more comprehensive,the conclusion will be more practical. |
