对外贸易与地区经济增长差距——基于中国省际面板数据的实证分析

The Effect of Foreign Trade on Regional Economic Disparity——An experiential research based on China's regional panel data

改革开放以来中国地区经济增长差距的不断扩大引起了各方面的普遍关注。本文运用Shorrock的分解方法分析对外贸易对中国日益扩大的省际经济增长差距的影响,发现1978-2005年对外贸易对省际经济增长差距拉大的贡献率为33.77%。接下来,本文将对外贸易影响地区经济增长差距的机制归纳为乘数机制、技术扩散机制、集聚机制和竞争机制。最后,本文指出缩小各地区对外贸易发展水平上的差异有利于平衡地区经济增长差距,促进各地区经济协调发展。

Since Open and Reform, the enlarging regional economic disparity in China aroused much attention. This paper uses Shorrock＇s method to decompose the effect of foreign trade on the widening of regional economic gap. The conclusion is that from 1978 to 2005, the contribution rate of foreign trade to the increasing regional economic disparity is 33. 77 percent. After that, this paper pointes out the mechanism through which foreign trade can work on the regional economic growth disparity. They are multiplier mechanism, technology transfer mechanism, agglomeration mechanism and competition mechanism. At last, this paper holds that reducing the regional disparity on foreign trade development can do well to the decline of regional economic growth disparity thus boost the harmonious growth among regions.
