Research On The Influe Ncing Mechanism Of Charginginfrastructure On The Promotion Of Electric Vehicles

With the increasingly serious energy and environmental problems,the major automobile producing countries have accelerated their strategic deployment and made the development of electric vehicles a national strategy.C hina is a big country in automobile production and marketing.Developing electric automobile industry is an important opportunity for C hina to transform from a big automobile country to a powerful one,and also the only way to deal with energy and environmental problems.Before 2014,the government tended to focus on purchasing subsidies.However,the production and sales of electric vehicles in C hina have not made great breakthroughs.In 2014,the policy of electric ve hicle industry entered the stage of adjustment.Tax relief,charging price concessions,road rights and government purchasing policies have been carried out simultaneously.At the same time,the government has begun to support the construction of charging facilities.As a result,the sales of electric vehicles advanced rapidly,but up to now,the difficulty of charging has not changed fundamentally.This paper theoretically analyses the influence of charging infrastructure on the promotion of electric vehicle market.Based on the panel data of 25 pilot cities of electric vehicles from 2011 to 2015,according to the theoretical model of relevant scholars,this paper measures the influencing factors of charging infrastructure ownership and electric vehicle pro motion respectively.,and demonstrates the mechanism of charging infrastructure on the development of electric vehicle industry through empirical analysis.The relevant policies to promote the construction of charging infrastructure in C hina is also included in the empirical study.The empirical research results provides a theoretical basis for the importance of charging infrastructure construction and increasing policy efforts to promote the construction of charging infrastructure.This paper finds out that charging infrastructure has a positive impact on the sales of electric vehicles through indirect network effects,and the quantity of electric vehicles can promote the improvement of charging infrastructure through indirect network effects,that is,charging infrastructure and electric vehicles have indirect network effects on both sides,so charging infrastructure has a positive impact on the promotion of electric vehicles through feedback loops.In addition,the government’s incentive subsidy policy and the establishment of charging pile installation service center can effectively promote the improvement of charging infrastructure,while the preferential policies for land use has not actually played a role.Therefore,the government should further strengthen the policy to promote the development of charging infrastructure industry,thereby accelerating the growth of electric vehicle demand.
