摘　　要：本文利用2003～2008年中国省区的面板数据,研究了进口贸易、外商直接投资和对外直接投资3条渠道传递的国际R&D对中国的技术溢出效果。研究结果表明,进口贸易和外商直接投资对中国全要素生产率、技术进步和技术效率均无显著的正向促进作用,对外直接投资却显著促进了国内全要素生产率提升和技术进步。分区域的回归结果进一步揭示,对外投资显著促进了东部和中部地区的全要素生产率增长,对西部地区的全要素生产率增长则无显著影响。在上述结论的基础上,论文对中国利用3条渠道的国际R&D溢出促进技术进步和经济发展提出了相应的政策建议。This paper estimated the international R&D spillovers of three channels including import,foreign direct investment and outward foreign direct investment by using provincial panel data from 2003 to 2008.The empirical results revealed that international R&D through import and FDI didn′t have positive impact on domestic total factor productivity,technical progress and technical efficiency,but international R&D through OFDI had promoted China′s total factor productivity and technical progress significantly.The regional regression results showed that OFDI had promoted the total factor productivity of Eastern China and Central China,but didn′t have significant impact on the total factor productivity of Wastern China.Based on the above conclusions,it gives the corresponding policy suggestions for promoting technology progress and economic development by making use of the international R&D spillovers of these three channels.
