摘　　要：本文利用2007—2021年上市企业专利数据,研究OFDI知识溢出对国内企业创新质量提升的影响机制及效果。研究发现:OFDI及非OFDI企业知识溢出对国内企业创新质量提升均具有促进作用;OFDI企业实用新型专利知识溢出的创新激励效应更为明显,发明专利知识溢出的创新激励效应则逊于非OFDI企业。进一步研究发现,吸收能力、供应商集中度及知识产权保护均显著挤占OFDI企业发明专利知识溢出的创新激励效应。This paper systematically explored the impact of knowledge spillover from both OFDI and non-OFDI enterprises on the enhancement of domestic enterprise,innovation quality using patent data from listed companies between 2007 and 2021.The findings reveal that the knowledge spillover from both OFDI and non-OFDI enterprises positively contributes to the enhancement of domestic enterprises,innovation quality.Notably,the innovation incentive effect is more pronounced in the utility model patent knowledge spillover of OFDI enterprises,while it is more evident in the invention patent knowledge spillover of non-OFDI enterprises.Even after conducting a series of endogeneity and robustness tests,the estimated results remain robust.Further investigation indicates that absorptive capacity,supplier concentration,and intellectual property protection significantly crowd out the innovation incentive effect of invention patent knowledge spillover in OFDI enterprises.The conclusions drawn from this study provide important policy insights for the implementation of enterprise innovation-driven strategies under the context of “dual circulation”.
