Review of the Theoretical Mechanism of Human Capital Investment Affecting the Enterprise Innovation Output

With the intensification of global competition and the accelerated advancement of technological transformation in enterprises, enterprises are confronted with the problem of insufficient innovation ability and urgently need to enhance their core competitiveness. Human capital promotes the development of enterprises through the accumulation of knowledge and ability, the improvement of technical level, and the stimulation of workers’ creativity, exerting a positive incentive effect on enterprises. The investment in enterprise human capital is mainly made through means such as education and training, career development, and health security, ultimately achieving the goal of enhancing the core competitiveness of the enterprise. This paper sorts out and analyzes the relevant literature, and elaborates on the mechanism and path of how enterprise human capital investment catalyzes enterprise innovation output from four aspects: theoretical basis, mechanism of action, empirical conclusion and future outlook, respectively, providing certain references for related research and practice.
