摘　　要：改革开放以来,中国经济得到快速发展,已成为贸易第一大国,但与贸易强国之间还有不小差距,发展进口贸易为我国由大国向强国转变提供了一个切入点。本文将从消费者异质性角度出发研究省际进口贸易总量和进口地区结构差异,并选取DLI指数衡量省际层面的消费者异质性。考虑到零贸易量问题,本文选取2000-2013年的平衡面板数据进行分析,考虑到内生性和稳健性问题,本文将选取工具变量GDP含金量和动态面板数据进行分析。基于引力模型扩展的实证结果与本文理论以及传统理论相一致,实证检验结果也是稳健的,说明消费者异质性对省际进口贸易的发展有促进作用,结合交叉效应,可以为省际贸易和经济发展的不平衡提供一定的参考依据。Since the Reform and Opening,China’s economic has developedrapidly,and has become biggest tradecountry.Butto be a trade power,there is still a long way togo,andthe development of import will provide a starting point to make China a trade power.This article studies provincial import trade volume and regional structure differencefrom the perspective of consumer heterogeneity,and use DLI index to measure the level of consumer heterogeneity. Considering the zero trade volume problem,this article chooses2000-2013 balance panel data to analysis,and considering the endogenous and robustness problems,this article selects instrumental variable（GDP value） and dynamic panel data to analysis.The empirical test results based on extended gravity model are consistent with the theory,and are also robust. We find thatconsumer heterogeneity has a promoting effect on the development of provincial import trade,and combining with the cross effect,it can provide certain reference basis for the unbalanced trade and economic development between different provinces.
