国际直接投资与进出口对技术效率的影响——基于中国省际面板数据的实证分析

The Influence of International Direct Investment and International Trade on Technical Efficiency: An Empirical Analysis Based on Provincial Panel Data

中国经济发展依赖于对外开放后贸易和投资的快速增长。文章基于中国的省际面板数据,首先采用DEA方法测算了技术效率及其分解变量纯技术效率和规模效率,进而研究了国际直接投资和进出口对技术效率的影响。研究结果表明,OFDI和进口对技术效率有显著的正向影响,FDI和出口对技术效率有显著的负向影响;分地区看,国际直接投资和进出口对东部地区的效率影响大于中西部地区,并且贸易的影响大于投资。最后,文章提出了利用国际直接投资和进出口提高各地区技术效率的政策建议。

China's economic development relies on the rapid growth of world trade and international direct investment. Based on China provincial panel data,using DEA to calculate the technical efficiency and its decomposition pure technical efficiency and scale efficiency,this paper analyzes the influence of the international direct investment flow and international trade on efficiency. Results show that the OFDI and import have a significant positive effect on technical efficiency and pure technical efficiency. FDI and export have significant negative influence,while foreign investment and trade have larger influnce on efficiency of eastern region than that in the central and western regions. At last,the paper puts forward policy suggestions to improve the technical efficiency through international direct investment and foreign trade.
