中文摘要：

依据转移份额分析法，将产业结构分解为构成效应与竞争效用，并运用我国省际面板数据，研究进口贸易对产业结构构成效应与竞争效用的影响。研究结论表明：在我国东中西部地区，进口贸易对产业结构构成与竞争效应都存在显著性的正向作用，即进口贸易的增加不仅有利于地区产业结构由不协调向协调、由低级向高级发展，也有利提高地区产业结构中优势产业的竞争力，保持产业发展中的竞争优势。另外，从地区间的比较分析发现，进口贸易对产业结构的构成与竞争效应影响效果都是由东向西逐渐递减的。

英文摘要：

Through the method of shift-share analysis, the effects of industry structure are de- composed into composition effects and competition effects, and influence of the import trade on regional industrial structure adjustment has been discussed. The results show that import trade promotes the composition effects and competition effects of industrial structure significantly in China＇s East, central and West Regions, which means the growth of import trade can not only promote industrial structure, but also increase industrial competition advantage. Moreover, from the comparative analysis among regions, the trend of spillover of import trade in different areas is degressive from the east to the west.
