产业结构调整对城市出口偏好具有重要影响。笔者通过对2004年~2012年285个地级城市的数据分析,发现表示产业结构合理性的指标——泰尔指数呈现波动发展趋势,并且东部城市泰尔指数明显较低,说明东部城市产业结构合理性较强。实证分析结果显示:产业结构泰尔指数对出口强度显著为负,表示产业结构合理性对外贸出口具有积极作用;东部和中部城市产业结构合理性的调整对出口强度具有正相关作用,而西部城市的影响不显著。
Industrial restructuring has an important impact on urban export preferences. By analyzing the data of 285 prefecture-level cities from 2004 to 2012, the author finds that the index showing the rationality of industrial structure shows a trend of fluctuation and the Theil index in the eastern city is obviously lower, indicating that the industrial structure of the eastern city Reasonable. The result of empirical analysis shows that the Theil index of industrial structure is significantly negative for export intensity, indicating that the rationality of industrial structure has a positive effect on the export of foreign trade; the rational adjustment of industrial structure in the eastern and central cities has a positive correlation with the export intensity; The impact is not significant.
