A Review of the Policy Incentive on Electric Vehicle Market Based on Citespace

Abstract

As the environmental problems increasing seriously, governments have to take environmental protection as one of the most important development directions in the future. Large emissions of greenhouse gases (GHGs) will accelerate the greenhouse effect. Comparing with the traditional fuel vehicles, electric vehicle (EV) is a cleaner technology with lower emissions, which can slow the pace of global warming effectively and it has been promoted by governments around the world vigorously. However, there are still some challenges in the development of EV, such as range anxiety, battery safety and so on which will influence consumers’ choices. In order to promote the promotion of new energy vehicles, the government has promulgated a series of incentive policies on EV area. Scholars from all over the world have also studied the policy impact in the field of new energy vehicles. By using CiteSpace literature visualization tool, this paper analyzes relevant literature on the web of science (WOS) to determine the policy influence in EV area. The results indicate the research background of this field. In another hand, costumer and energy supply are the two important impact factors in this area.
