A New Energy Vehicle Development Evaluation Model Based on Cluster Effect and Cobb-Douglas Utility Function

It is significant to evaluate the development level of new energy vehicles quantitatively and analyze the effects of the support policies promulgated in this field. The former scholars used the static analysis methods of subjective and objective combination which made the persuasive power of the results greatly reduced due to the limitations in time and space. This paper establishes a quantitative analysis of the development level about new energy vehicles in selected cities by establishing a developmental evaluation model based on Cobb-Douglas utility function. Then examine the exogenous effects of cluster and plunder effects brought by policies on the development of new energy vehicles and make a second revision of the quantitative analysis results obtained before. Finally, the sensitivity analysis results of the established model show that it has high accuracy.
