Research on the Development of China's New Energy Vehicle Industry Based on Spearman's Model

Abstract

This study aims to explore the development of China's new energy vehicle industry and proposes a model and solution for two problems. First, by analyzing the impact of six factors on the development of the new energy vehicle industry, including policy support, technological development, individual purchasing ability, infrastructure, energy price and environmental awareness, and establishing a Spearman model to analyze the correlation between them and the industry development indicators. Based on the results of the analysis, the indicators of China's new energy electric vehicle sales, China's new energy R&D investment, China's number of charging piles and per capita GDP were selected, and the weights of the indicators were determined using the independent weight coefficient method, and a model of the development trend of China's new energy automobile industry in the next ten years was established by fitting the time variable. Finally, through the model prediction, we find that the new energy vehicle industry will develop rapidly and show exponential growth in the next decade.
