| 摘要: |
| 对汽车销量影响因素进行了研究分析，基于传统的GRA和熵权法基础，对两种方法进行加权分析，选取出前5种主要影响因素，再构建VAR模型深入研究各个因素对汽车销售量的影响；结果表明各影响因素之间相互联系、牵制，其中GDP和钢材产量对汽车销售量影响更明显，且随着年份的增加，影响更加显著。 |

| Abstract: |
| This paper proposes to study and analyze the factors affecting auto sale，based on traditional GRA and entropy weight method，conducts weighted analysis on the two methods，selects former five factors and then builds VAR model to deeply study the influence of various factors on auto sale. The results show that each factor is connected and coupled，among which the influence of GDP and steel output on auto sale is more significant，but with the increase of the time，the influence on auto sale is more remarkable. |
| Key words: auto sale influencing factor comprehensive entropy weight method VAR model |
