Using a panel cointegration method incorporating structural breaks and cross-sectional dependence, this paper explores the long-run equilibrium relationship between innovation and foreign direct investment (FDI) in 30 OECD countries. The results from the panel stationary test show that FDI and innovation variables follow a stationary process with several structural breaks over the period 1999–2018. The results also suggest an equilibrium relationship with structural breaks between FDI and innovation in OECD countries. The panel dynamic OLS model with breaks further reveals that FDI is positively associated with innovation performance and vice versa in OECD countries. Therefore, this paper sheds light on the relationship between FDI and innovation in OECD countries.

创新和外国直接投资评估：对经合组织国家的调查

本文使用结合结构断裂和横截面依赖的面板协整方法，探讨了 30 个经合组织国家创新与外国直接投资 (FDI) 之间的长期均衡关系。面板平稳测试的结果表明，在 1999 年至 2018 年期间，外国直接投资和创新变量遵循平稳过程，并出现多次结构性断裂。结果还表明，经合组织国家的外国直接投资和创新之间存在结构性断裂的均衡关系。带有中断的面板动态 OLS 模型进一步揭示了 FDI 与 OECD 国家的创新绩效正相关，反之亦然。因此，本文阐明了经合组织国家 FDI 与创新之间的关系。
