摘　　要：京津冀地区共同构建面向国际化的开放平台,为外商直接投资(foreign direct investment,FDI)流入和创新活动的开展提供了新的机遇。基于京津冀地区各城市2011-2021年的面板数据,考察京津冀利用FDI影响自主创新的作用及机制。结果表明,京津冀利用FDI对其自主创新能力存在显著的促进作用,该促进作用受到高等教育学生人数的正向调节,并且伴随着地区数字经济的发展呈现非线性影响;产业结构高级化是京津冀利用FDI影响自主创新的途径之一。地区异质性结果显示,外部地区利用FDI对自主创新的促进作用大于中部核心功能区;年份异质性结果显示,伴随着协同战略的实施,京津冀地区利用FDI对自主创新能力的促进作用由不显著转变为显著促进。The Beijing-Tianjin-Hebei region has jointly built an open platform for internationalization,providing new opportunities for FDI inflows and the development of innovative activities.Based on the panel data of cities in the Beijing-Tianjin-Hebei region from 2011to 2021,the role and mechanism of FDI in influencing independent innovation in the Beijing-Tianjin-Hebei region was examined.The conclusions of the study are as follows.The use of FDI in the Beijing-Tianjin-Hebei region has a significant promoting effect on its independent innovation ability,which is positively moderated by the number of higher education students,and has a nonlinear impact with the development of regional digital economy.The upgrading of industrial structure is one of the ways to use FDI to influence independent innovation in Beijing-Tianjin-Hebei.The results of regional heterogeneity show that the use of FDI in external regions has a greater promotion effect on independent innovation than in the central core functional area,and the results of annual heterogeneity show that with the implementation of the synergy strategy,the promotion effect of FDI on independent innovation capability in the Beijing-Tianjin-Hebei region has changed from insignificant to significant.
