摘要
R&D投入、国际贸易和R&D溢出对发展中国家的技术进步至关重要,其中国际R&D溢出对发展中国家技术进步的正面效应已得到大量文献支持。对发展中国家模仿性技术进步理论的拓展进一步支持了国际贸易对其技术进步的重要推动作用,但同时暗示其可能存在的负面效应。利用1996-2007年中国工业行业面板数据,对中国各行业Malmquist全要素生产率指数、R&D投入和国际贸易这三者关系进行的实证分析支持了上述理论结论。结果表明,中国各工业行业技术进步主要得益于国内R&D投入,同时受到国外R&D溢出的正面影响,而出口增长却阻碍了国内技术进步。
National R&D investment,international trade and R&D spillovers are vital for a developing country to develop its technology.A number of empirical studies have proved the positive effects of international R&D spillovers in this respect.By extending the current theoretical model of international technology diffusion and imitation,this article analyzes the key determinants related to the technological imitation and innovation on the side of developing countries.Moreover,the contribution to technological development upon domestic R&D accumulation and international R&D spillovers is verified in our empirical studies of the relationship between international trade,R&D investment and TFP changes in manufacturing sectors in China in 1996-2007.Unfortunately,the effect of export activities is negative as the study shows.
