劳动力成本上升对数字技术创新的影响OACHSSCD

From the perspective of measuring digital technological innovation based on soft-ware,and using data from listed companies from 2003 to 2019,this study applies a difference-in-differences(DID)model to examine the impact of labor costs on digital technological innovation.The results show that rising labor costs primarily promote digital technological innovation through two channels:the"factor substitution effect"and the"efficiency-forcing effect".These effects intensify firms' reliance on human capital in software R&D and heighten competitive sur-vival pressure,thereby transforming into endogenous drivers of digital technological innovation.Heterogeneity analysis reveals that the promoting effect is significant in competitive industries,but relatively weaker in monopolistic industries and in regions outside"Beijing,Shanghai,Guangzhou,and Shenzhen".Firms exhibit stronger incentives to develop application-oriented software,while their motivation to develop underlying software is comparatively weaker.In light of these findings,it is necessary to strengthen the coordination between human capital develop-ment and innovation strategies,optimize the structure of digital technological innovation,focus on breakthroughs in core underlying technologies,promote the construction of digital infrastruc-ture and the integrated allocation of innovation resources,enhance anti-monopoly regulation,and stimulate firms' vitality in digital technological innovation,thereby fully unleashing the potential of labor cost pressures to be transformed into drivers of digital technological innovation.
