Abstract: Based on the provincial-level consumer demand function,this paper uses 2000~2013 panel data of 14 provinces to study the provincial import trade. The findings show that the provincial import trade has significantly positive correlation with the GDP of both sides of the trade and consumer heterogeneity on provincial level,and is negatively related to the distance and cost of the trade. Moreover,the paper analyses the cross effect of each province's characteristics,regional features and the structure differences, with a view to promote the balance of provincial import trade and provide a certain basis for economic development.

Key words: Provincial Differences of the Import Trade, Consumer Heterogeneity, GDP Value, Regional Development and People's Livelihood Index

摘要： 本文基于省际层面的消费者需求作用,利用2000～2013年14个省份的面板数据对省际进口贸易进行分析。研究结果表明,省际进口贸易与贸易双方的GDP和省际层面的消费者异质性显著正相关、与贸易距离和贸易成本负相关。同时,分析各省份自身特性、区域特性和进口地区结构差异的交叉效应,为促进省际进口贸易与经济平衡发展提供依据。
