中文摘要：

中国出口的内部区域结构非常不平衡，无论从出口额、出口增长率，还是出口依存度来看，省份间出口的巨大差异都是客观存在的，而这种差距又主要是由于东、中、西三大地带间的差距造成的，从发展趋势看，目前没有扭转的迹象。进一步的实证分析揭示，各省的出口与各省的经济增长之间存在着显著的正向关联，也就是说，不同的省份间，出口的差异部分地解释了省份间经济增长的差异，而且出口的增长效应在东、中、西三大地带各异，出口对经济增长的促进作用，中部最大，西部次之，而东部最低。

英文摘要：

Seen from the angle of export volume, export growth rate, or export dependence degree, the internal regional structure of China＇ s export is extremely unbalanced. The great difference between the exports of different provinces exists objectively, and the difference is manly caused by the differences of eastern, middle and western regional differences. From the angle of development tendency, the situation cannot be changed at present. Further empirical analysis shows that positive correlation exists between the export and economic growth of different provinces, that is to say, export differences among different provinces can partly explain the economic differences among the provinces, and the export growth effect is different among eastern, middle and western regions. The promoting effect of export to economic growth is the greatest in middle region, followed by the western and eastern regions respectively.
