Abstract: Quantitative evaluation of the effects of the new energy vehicle industry policy is conducive to providing a basis for the formu- lation and adjustment of China's follow-up policies. Based on the behavioral utility function of consumer vehicle demand and by choosing the monthly data of China's new energy passenger car market share in 2012-2018 as dependent variable, four government policies (re- garding financial subsidies, purchase tax exemption, no restrictions on the use and purchase of new energy vehicles and government/pub- lic procurement respectively) as independent variables and the selling price of new energy vehicles, battery prices, the difference be- tween oil and electricity prices, the number of new energy vehicle battery patent applications and the number of charging piles as control variables, this paper uses the time series cointegration model and error correction model to quantitatively evaluate the effects of the four policies. The findings are as follows. Firstly, in 2012-2018, the four policies all have a positive effect on the promotion of China's new energy vehicles and among them, the financial subsidy policy has the largest effect. Secondly, the effect of financial subsidies gradually increased from 2012 to 2016, but began to decrease from 2017 to 2018. In addition, each 1% increase in the new energy vehicle pro- curement by government and public institutions will lead to an increase of 0.331% in the market share of new energy vehicles; each 1% increase in car purchase demand suppressed by the purchase restriction policy will lead to a 0.312% increase in the new energy vehicles market share. So far as the controll variables are concerned, an increase in the price of new energy vehicles and battery is not conducive to the promotion of new energy vehicles, and the difference in the prices of petrol and electricity, the number of battery technology patent applications, and an increase in the number of charging piles has a positive effect on the promotion of new energy vehicles in the long term.
