摘　　要：在研究过程中,先从国家统计局等官方网站搜索数据,再用EXCEL对数据进行整合,筛选出目标数据,其次绘制散点图进行可视化分析。然后利用收集到的近十年长三角地区的新能源汽车保有量、销量等9类数据,进行TOPSIS评价法以及熵权法的综合运用,分析得出长三角地区以及所属四个省市的重要权重以及排名,最后通过SPSSPRO运用灰色预测模型GM(1,1)预测出未来3年长三角地区新能源汽车的市场保有量,进而提出改善新能源汽车的优化模型,也能促进新能源汽车市场的健康发展。First,the data was searched from the official websites such as the National Bureau of Statistics,then EXCEL was used to integrate the data,screen out the target data,and then the scatter plot was drawn for visual analysis.Then use the collected nearly ten years in Yangtze river delta region of new energy car ownership,sales and other 9 types of data,TOPSIS evaluation method and the integrated use of entropy method,analysis of the Yangtze river delta region and four provinces and cities important weight and ranking,finally through the SPSSPRO using gray prediction model GM(1.1)predicts the next three years in Yangtze river delta of new energy automobile market ownership.
