技术效率视角下我国服务业外资溢出效应研究

The spillover effects of service industry FDI with the viewpoint of technical efficiency

本文利用我国2001-2007年间分省面板数据和随机前沿分析模型,从技术效率这一视角研究了我国服务业外商直接投资的溢出效应。研究结果不仅表明,我国中西部地区服务业技术效率显著地低于东部沿海地区,而且服务业外商直接投资与服务业技术效率之间存在着显著的倒U型关系。由于我国中西部地区服务业外商直接投资依存度比较低;因此,提高服务业外商直接投资依存度是促进中西部地区服务业技术效率提升的有效手段。但是,对于东部沿海地区来说,由于服务业外商直接投资依存度已经处于较高的水平上,且位于倒U型曲线的右边;因此,东部沿海地区服务业技术效率的持续提升应该着眼于其它因素而非提高外商直接投资依存度。

From the viewpoint of technical efficiency, the stochastic frontier model and the cross - province panel data in the year from 2001 to 2007 are utilized to study the spillover effect of Service Foreign Direct Investment （SFDI） in Chinese mainland. The empirical estimations not only show that average technical efficiency in the central and western region is significantly lower than that in eastern coastal regions, but also find that a significant inverse U - shape effect between technical efficiency of service in- dustry and SFDI exists. Because the central and western region＇ s service industry absorb few FDI and have very low technical efficiency, continuous absorbing SFDI is an available and positive way for central and western regions to improve technical efficiency of service industry. However for the technical efficiency in eastern coastal regions, the level of absorbed SFDI is beyond the optimal value in the ＂inverse U shape＂, therefore the reasonable path for improving technical efficiency in eastern coastal regions should focus on other factors rather than increasing level of SFDI.
