摘要
利用中国近十年汽车产业的相关数据,首先,采用Topsis(逼近理想方案排序法)综合评价模型刻画了中国新能源汽车产业的发展程度;接着利用皮尔逊(Pearson)相关性分析方法,分析了新能源汽车发展的影响因素,分析结果表明中国动力电池装机量、公共充电桩保有量对新能源汽车的发展影响显著;最后,采用ARIMA(自回归滑动平均模型)模型预测了中国新能源汽车未来十年的销量.
Abstract
Based on the relevant data of China's automobile industry in the past ten years,Topsis(technigue for or-der preference by similarity to an ideal solution)comprehensive evaluation model is adopted to numeralize the develop-ment degree of China's new energy automobile industry.Secondly,by using Pearson correlation analysis method,the influ-encing factors of the development of new energy vehicles are analyzed,and it is concluded that the installed capacity of power batteries and the number of public charging piles in China have a significant impact on the development of new energy vehicles.Further,the ARIMA(autoregressive integrated moving average)model is used to predict the sales trend of new energy vehicles in the next ten years.
