Improvements of export sophistication of manufacturing industry is a key way to cope with inadequate foreign demand and development pattern change, however dose the improvement of export sophistication increase capital return? In order to answer this question, this paper takes advantage of the methods, which is put forward by other scholars to calculate the export sophistication and capital return of China on provincial level, then estimate the effects of export sophistication to capital return and find the way to better them. The results show that: on the one hand, the effect of export sophistication to capital return is negative ,which is even larger than the negative effects of capital deepen to the capital return, the main reasons to this situation are China’s reverse comparative advantage and foreign power dependent catch-up behavior. On the other hand, FDI export consumption and human capital can improve the capital return of different province ,single Interaction effects of above factors with export sophistication can’t relieve the restrain effects ,but double combination interaction effects of above factors with export sophistication can relieve even reverse the restrain effects. Finally, based on the above results, this paper puts forward some constructive suggestions.
