采用DEA法测算了广西1978～2011年的全要素生产率水平，并利用Tobit模型对广西基于进口渠道的国际技术溢出效应进行了实证研究。结果表明，通过从G7国家进口的方式，显著地促进了广西的全要素生产率水平的提高。然而，广西的自主研发对全要素生产率的提高起到了抑制作用，且从回归系数的显著性水平来看，即使是在很高的显著性水平下仍不显著；引入人力资本变量后， G7国家的综合研发资本存量对广西全要素生产率的作用大幅下降，且自主研发对全要素生产率的抑制作用更为强烈，这可能是因为广西的人力资本水平过低，未达到吸收国外先进技术的门槛值所致。

Using the data during 1990-2007 , this paper investigates the impacts of technology spillover through import on the productivity growth of Guangxi based on Malmquist productivity index measured by DEA method after setting up a Tobit model.The paper finds that technology spillovers by import from G 7 countries have significantly positive impact on the productivity growth of China.However , independent R&D investment in Guangxi has signifi-cantly negative impact on the productivity.By introducing human capital variables , G7 country's R&D capital stock play a role in the TFP of Guangxi but dropped significantly.Independent R&D investment inhibits TFP more strong-ly.Maybe that ’ s because human capital of the Guangxi is at a low levels and it has not reached the threshold of ab -sorbing foreign advanced technology.
