我国FDI流入的经济效率分析--基于地级市动态面板数据模型

Study on Economic Efficiency of FDI Inflows in China:Based on Dynamic Panel Data of Prefecture- level City

文章利用2003-2012年期间我国246个地级市数据,借助DEA方法测量出不同地市的M almquist指数,并通过基于工具变量的固定效应面板回归模型,实证研究了外商直接投资对地区经济效率的影响。结果表明,自2003年以来,全国经济效率逐渐上升,约累计提高了37.1%,但是东部、中部和西部三大区域的经济效率及其增速各不相同。控制其他影响因素后,发现FDI能够有效促进所在地的经济效率,特别是在经济相对发达的东部和经济效率较高的地市。地区经济越发达、经济效率越高,则FDI提升当地经济效率的作用越显著。

Through panel data of Chinese 246 prefecture -level city between 2003 and 2012, this paper analyses the impact of FDI on regional economic efficiency, by using DEA method to measure cities＇ Malmquist index and applying fixed - effect model based on instrumental variables. The results show that Chinese economic efficiency has totally increased about 37. 1 percent since 2003, while economic efficiency among eastern, central and western areas are different. What＇s more, after controlling other influence factors, FDI can significantly promote local economic efficiency, especially in relatively developed eastern district as well as relatively high efficient areas. The more prosperous and more efficient local economy is, the more notable positive effect of FDI is.
