Study On The Effect Difference Of Different Downhill Modes Of Government-subsidized New Energy Vehicles

With the development of economic and social,energy problem is increasingly serious,developing new energy vehicle is an effective way to alleviate the energy crisis and promote social development of our country.In terms of the supply side,the development of new energy vehicles is an important support for China’s construction of a great modern socialist country.In terms of the demand side,the development of new energy vehicles can promote our national economy’s circulation,stimulate the rapid and steady growth of economy,and the development of new energy automobile industry is of great significance to our country.China’s new energy vehicles,which have been supported by promotion policies,have lived up to expectations and walked out of a beautiful growth arc,but long-term subsidies have led to the lack of market competitiveness of enterprises and other problems.Therefore,in2016,the state issued a subsidy retreat policy for the new energy vehicle industry,but hasty retreat will lead to a significant decline in sales of new energy vehicles.It is necessary to choose a set of scientific and reasonable subsidy retreat policy.Therefore,based on the National Natural Science Foundation project as the background,this paper studies the different impact of different slope withdrawal policies on the new energy vehicle market.First,the Stackelberg game model among government,enterprises and consumers is established,and the price,sales volume,enterprise income,consumer surplus and total social welfare of traditional and new energy vehicles are calculated under the producer regression model,consumer regression model and synchronous regression model.Second,the static comparison and dynamic analysis of the results among the models are carried out.The research shows that when the greenness is low,the synchronous regression mode will bring higher benefits to enterprises and consumers,and when the greenness is high enough,the producer regression mode and consumer regression mode will bring higher benefits to enterprises and consumers,and it is easier to realize larger total social welfare than the synchronous regression mode.This paper found the significant difference in the impact of different government subsidy regression modes on the new energy vehicle industry,providing theoretical support for how to reasonably realize the new energy vehicle subsidy regression.
