摘　　要：本文运用1999-2016年中国25个工业行业面板数据研究了国内R&D投入与国际R&D溢出对工业生产率的共同影响。通过加入以R&D人员密度衡量的人力资本变量及其与国际R&D溢出资本存量的交互效应,结果发现:我国R&D人员密度和国际R&D溢出对生产率有显著促进作用,但国内R&D资本投入对生产率无显著影响。国内R&D投入与国际R&D溢出交互项系数不显著,表明我国对外国先进技术的吸收能力较低。国有产权变量与生产率进步没有显著关系,但三资企业的研发活动却显著促进了生产率的提高。Using a panel dataset of 25 industries in China from 1999 to 2016,we study the combined effects of domestic R&D investment and international R&D spillovers on industrial productivity.By adding human capital measured by the proportion of R&D workers and its interaction effect with international capital spillover,we derive three conclusions.First,the proportion of R&D workers and international capital spillovers have significant positive effect on productivity,but the domestic R&D capital investment have no significant impact.Second,the insignificant interaction effects of domestic R&D investment and international R&D spillovers indicates that the ability of adopting foreign advanced technology is limited.Third,state-owned property has no effect on productivity progress,but research activities of foreign-funded enterprises augment productivity significantly.
