How do human capital and R&D structure facilitate FDI knowledge spillovers to local firm innovation? a panel threshold approach
研究北京中关村科技园企业数据，发现人力资本多样性和研发多样性存在门槛效应，影响FDI知识溢出对本地企业创新的作用。
Abstract This paper examines how local firms’ structure of human capital and R&D strategies influence their absorption of FDI knowledge spillovers. Using a unique dataset of Chinese firms in Beijing Zhongguancun Science Park from 2009 to 2015, our panel endogenous threshold models confirm two thresholds for human capital diversity and one threshold for R&D diversity in facilitating FDI spillovers. When human capital diversity is below its second threshold, FDI presence positively influences local firms’ innovation performance; while above the second threshold, the FDI turns to an insignificant impact. Besides, when R&D diversity is below its single threshold, FDI spillovers are positively associated with local firms’ innovation; otherwise, the effect of FDI is insignificantly negative. Our findings highlight the importance of human capital and R&D structures in local firms’ absorptive capacity. Local organizations need to keep diversifying their human capital and R&D strategies to learn from FDI knowledge but avoid allocating their efforts evenly upon sub-categories within the two resources.
