摘　　要：国际贸易使国外R&D的外部性扩展到国内,于是一国全要素生产率的增长可以突破单一国家的限制,国际贸易成为技术溢出的重要渠道。由Coeand Helpman开创的通过构造"国外研发资本存量"变量,以国际R&D溢出分析框架研究贸易的技术溢出的方法被广泛地应用于宏观、中观和微观层面的研究。宏观层面,学者们从计量方法、国外R&D测算、溢出渠道、溢出条件几个方面拓展了CH模型;中观层面,国内外行业内、行业间的R&D溢出得到区分和比较,行业的技术特征对溢出效果的影响得到关注;微观层面,研究的结论相当多元,难于得出进出口贸易提高企业生产率的结论。International trade extends R＆D externality from overseas to domestic markets, which leads to the breaking-through of a single national market limitation in the growth of domestic total-factor productivity. Thus, international trade becomes an important channel for technology spillovers. The approach initiated by Coe and Helpman- ＂by constructing variable of ＇foreign R＆D capital stock＇ to analyze international R＆D spillovers＂ has been widely applied in researches on different scopes. At the macroscopic level, researchers expand CH model from econometric method, foreign R＆D estimation, spillover channel, spillover condition and so on. At the mediumscopic level, R＆D spillover effects of intra-industry and inter-industry are distinguished and compared, and the effects of industrial technology characteristics are paid attention to. At the microscopic level, conclusions are diversified, and it is hard to conclude that trade enhances the efficiency of enterprises. In the end, the paper summarizes the researches at home and points out the directions for further researches.
