中文摘要：

聚焦中国对非洲直接投资的效率评价问题,笔者运用超效率DEA方法,选取2008年~2014年中国对非洲投资20个东道国的数据进行实证研究,以反映中国对非洲投资效率的差异和变化趋势。结果表明：中国对非洲多数东道国直接投资效率处于中、低水平且投资效率的国别差异较大,对多数国家投资的效率呈现出稳中有升趋势。中国对非洲各东道国投资效率呈现出收敛态势,投资效率高的东道国空间集聚效应明显。笔者提出了调整投资规模、优化投资区位选择、采取有效投资风险防控策略,实施本土化策略,增强投资产业集聚能力,改善非洲投资环境,提高东道国投资利用水平等对策建议。

英文摘要：

This paper focused on the evaluation of China＇s direct investment in Africa efficiency,used super efficiency model of DEA,chose top 20 host countries in aspect of China＇s investment in Africa（ 2008- 2014） for the empirical study,to reflect the difference and changing trends of the efficiency of China＇s investment in Africa. Results showed that： Chinese efficiency of investment in most Africa＇s countries is on a low level. And there are large national differences in investment efficiency. And investment efficiency in most countries increased steadily. In addition,China＇s direct investment in Africa presents convergence and space centralization effect.There is some enlightenment and suggestion： adjust the investment scale,optimize the investment location choice,take effective investment risk prevention and control strategy,implement localization strategy,enhance the capacity of investment industrial concentration,improve the investment environment in Africa,increase the utilization level of the host country investment.
