Abstract: In the context of the irreversible and deepening of population ageing, the focus of the innovative country lies in the technological innovation. This paper uses the mediation model and the panel threshold model to verify the impact of population ageing on labor productivity through technological innovation pathway, and the transitional impact of technological innovation on labor productivity with population ageing as a threshold variable. The findings show that regardless of binding economic conditions, population aging has a mediating effect on labor productivity through technological innovations in addition to directly affecting labor productivity. When population ageing is viewed as a threshold variable, the impact of technological innovations on labor productivity is positive. When control variables are included, the influence of technological innovations on labor productivity becomes negative. The influence of innovations on labor productivity shows varying effects. During the demographic transition of the East area, the effect of technological innovations on labor productivity is in line with the mechanism of technological innovations on economic development.
