FDI技术溢出、协同创新及其互动对制造业技术升级的影响

The Influence of FDI Technology Spillover,Collaborative Innovation and Their Interaction on Manufacturing Technology Upgrading

基于2010—2018年中国制造业上市公司与地级市的匹配数据,实证分析外商直接投资(foreign direct investment,FDI)技术溢出和协同创新及两者互动对制造业技术升级的作用,并进一步检验了不同企业所有制和产业类型下的异质性影响。研究发现,FDI技术溢出和企业间协同创新能显著促进制造业技术升级且形成积极交互效应,而产学研协同创新对技术升级的作用不显著,尚未与FDI技术溢出形成合力;在国有企业和技术密集型行业,FDI技术溢出与企业间协同创新的交互效应更为显著。

Based on the matching data of China’s manufacturing listed firms and prefecture-level cities from 2010 to 2018,the role of FDI technology spillovers,collaborative innovation and their interaction on manufacturing technology upgrading were empirically analyzed,and the heterogeneity under different enterprise ownership and industry types was further tested.It is found that FDI technology spillovers and inter-enterprise collaborative innovation can significantly promote manufacturing technology upgrading and form a positive interaction effect,while industry-university-research collaborative innovation has no significant effect on technology upgrading,and has not yet formed a synergy with FDI technology spillovers;in state-owned enterprises and technology-intensive industries,the interaction effect of FDI technology spillovers and inter-enterprise collaborative innovation is more significant.
