Abstract: The supply and demand side policies need to be favorably interacted with “government procurement market”; “commercial operation market” and “private procurement market”. It is a key problem urgently to be solved in China's new energy vehicle industry. Based on the comparative perspective of the heterogeneous markets, this paper uses panel data regression and panel quantile regression to analyze the difference effect on the new energy vehicle demand market between the supply side policies and the demand side policies. The results show that the three types of heterogeneity markets show different development potentials and paths due to the different formation reasons and different target consumer. The effects of the supply and demand side policies on the three heterogeneous markets are different, and the demand side policies has more significant effects than the supply side policies. The incentive effect of the supply and demand side policies of new energy vehicle changed with the different size of the three heterogeneity markets. The government should fully consider the heterogeneous and different scale of market, when formulating policies for the new energy vehicle industry, and implements differentiated policies.
