中文摘要：

基于“技术锁定”和转型升级的考虑，本文首先探讨了全球价值链下逆向技术外溢的微观机理和实际效果，并运用1985--2010年间相关数据测算我国OFDI渠道吸收的主要国家研发资本存量，采用国际R＆D外溢回归方法实证分析了OFDI逆向技术外溢对我国技术进步的影响．结论显示：逆向技术外溢正效应凸显，但其作用远小于国内研发资本的积极作用；流向发达国家的投资产生的逆向技术外溢强于发展中国家的投资回报．

英文摘要：

Considering the ＂technology-locking＂ and the urgent to upgrade, it firstly discusses micro-mechanism of reverse technology spillover effect on OFDI and the present situation. By analyzing relevant data ranging from 1985 to 2010, it measures several countries＇ R＆D stock acquired from OFDI spillover and analyzes Chinese OFDI reverse technology spillover by adopting the method of international R＆D spillover regressions. Results show that the positive effect on reverse technology spillover is emerging, but its contribution is less than the parts produced by domestic R＆D expenditures. Spillover effect generated by developed countries＇ investment is stronger than that generated by developing countries＇ investment.
