摘　　要：基于区域贸易差距视角,纳入国外技术这一冲击区域贸易差距的影响因子,利用我国1997-2010年省级面板数据探求国外技术溢出冲击、区域贸易差距与中国经济增长之间的相互作用机制。研究结果发现,区域贸易差距对中国经济增长作用具有倒U型关系,并计算其拐点值为2.909;当把国外技术溢出冲击与区域贸易差距联系起来考察区域贸易差距对经济增长的边际效应时,这种边际效应不仅与国外技术溢出冲击大小有关,而且与区域贸易差距和国外技术溢出冲击相互作用有关。其根本条件是看区域贸易差距在临界值范围内,二者是互补关系还是替代关系,并计算其临界值为1.845。随后我们分析了实证结果的可能原因。Based on the perspective of regional trade gap,and taking the foreign technology as one of the influence factors of regional trade gap,we want to explore the inner link among foreign technology spillover impact,regional trade gap and China economic growth by using the provincial panel data from 1997 to 2010. The results showed that it exists the inverted u-shaped relation between the regional trade gap and China economic growth,and calculate its inflection point value of 2. 909. When we discuss the marginal effect of regional trade gap on economic growth if associating foreign technology spillover impact with regional trade gap,the marginal effect is not only related to the size of foreign technology spillover impact,also is related to the interactions between regional trade gap and foreign technology spillover impact,and the fundamental conditions depend on the relations that they are complementary or alternative within the scope of the threshold,also we calculate the threshold value of 1. 845. Then we analyzed the possible causes of the empirical results.
