摘要
选取双重差分模型对汽车购置税优惠政策实施效果进行评估,以1.6L以下(包括1.6L)及1.6L以上排放量的汽车销量作为被解释变量,把汽车排放量分为实验组和对照组,设置政策实施虚拟变量以及国内生产总值这个控制变量进行回归分析。研究结果表明,车辆购置税优惠政策对促进优惠对象小排量车销量增加的作用显著。因此,建议再次出台该政策以促进汽车消费,进而拉动国内经济增长。
The double difference model is selected to evaluate the effect of the preferential policy on automobile purchase tax.The vehicle sales volume below 1.6 L(including 1.6 L)and above 1.6 L are used as the explanatory variables.The vehicle emissions were divided into experimental group and control group.The results show that the preferential policy of vehicle purchase tax has a significant effect on promoting the increase of small displacement vehicle sales.Therefore,it is suggested that the policy be introduced again to promote car consumption and then stimulate domestic economic growth.
