摘要
本文以我国高技术产业为例,实证分析了吸收能力对FDI知识溢出、进而对内资企业创新能力的影响。结果表明,以R&D投入强度表征的内资高技术企业的吸收能力对于FDI知识溢出效应具有非线性影响,两者呈现出"U型"关系,即吸收能力对于FDI知识溢出效应的作用存在一个临界值,只有当内资企业R&D投入强度超过这一临界值时,才能有效吸收FDI渠道溢出的知识;内资企业自主R&D投入始终是其创新能力提升的最重要因素;企业平均规模越大,其创新能力越强。
This paper examines the effects of absorption capacity of domestic high-tech enterprises on knowledge spillovers of FDI, using panel data of 17 sub-sectors of the high-tech industries in China. We find that absorption capacity of domestic high-tech enterprises which is measured by the R＆D investment intensity has a non-linear effect on knowledge spillovers of FDI, showing an ＂U＂ curve. That is to say there is a threshold in the absorption capacity, and only if the R＆D investment intensity exceeds the threshold, the domestic high-tech enterprises can absorb the knowledge spillovers of foreign enterprises. Further more, the independent R ＆ D investment has been the most important factors of inno- vation abilities. And the bigger the average sizes of domestic enterprises, the greater the innovation abilities are.
