为研究不同来源国的FDI对我国企业的技术效率溢出效应，本文以中国1998-2012年的省际面板数据为样本，选取资本、劳动和CO2作为投入，结合使用一阶段SFA和面板门槛技术开展了经验分析。结果表明：（1）韩国&新加坡投资和其他国家投资的溢出效果大于G7投资和港澳台投资，并且除了港澳台投资外，其他来源国的FDI在沿海地区的溢出效应均大于内陆地区；（2）良好的市场化程度和人力资本水平，能够通过直接刺激和间接传导的双重渠道去提升我国企业的技术效率水平；（3）在门槛效应分析中，G7投资在市场化程度和人力资本水平上的门槛取值最高，而韩国&新加坡投资仅需要较低的门槛取值就能够最大程度地提升技术溢出的效果。该结论意味着各省份在引进外资时，既要杜绝低水平外资的引进，也要避免对高水平外资的盲目崇拜，可以因地制宜地采取梯度式引进法，以此来保障其对内资企业技术效率的平滑式和跨越式双重激励。同时，还应当注重提高我国市场化程度和人力资本水平，增强它们对技术效率直接和间接的双重促进。

The paper takes the sample of inter-provincial panel data between 1998 and 2012 with capital, labor and carbon dioxide as inputs and makes empirical analysis by means of the one-stage SFA and Panel Threshold methods to study the spillovers of FDI from different source countries on technical efficiency of China’s enterprises. The results show those: (1) the spillovers of FDI from South Korea and Singapore and FDI from other countries exceed those of FDI from America, Britain, France, Germany, Italy and Japan (G7) and FDI from Hong Kong, Macao and Taiwan, and except of FDI from Hong Kong, Macao and Taiwan, the spillovers of other types of FDI in Western China are less than those in Eastern China; (2) the better degrees of marketization and human capital can improve the technical efficiency of China’s enterprises directly and indirectly; (3) in order to observably improve the technical efficiency of China’s enterprises indirectly, FDI from G7 needs the biggest threshold levels in degrees of marketization and human capital, while FDI from South Korea can maximize the spillovers with the smallest threshold levels. Such results mean that we should have scalar attraction of FDI by avoiding low-level FDI and arbitrary selection of high-level FDI according the actual situation of China’s provinces to ensure smooth and leapfrog stimulation for China’s enterprises. What’s more, we should pay more attention to improve the degrees of marketization and human capital aiming to improve technical efficiency directly and indirectly.
