This paper explores the influence of employee perception of psychological contracts on knowledge innovation from the perspective of open innovation. The purpose is to explore internal factors affecting knowledge innovation through the construction of the SEM model and provide enterprise managers with scientific and effective management methods. The survey sample includes 312 technical and scientific research employees from 16 high-tech enterprises in China. This study adopts a quantitative research method and conducts a questionnaire survey through the subjective sampling method of improbability sampling. Through empirical analysis, the results show that a psychological contract has a significant positive effect on knowledge innovation. Among them, the relational psychological contract is more influential than the transactional one. The influence of the relational psychological contract on organizational commitment is extremely significant; the influence is more than 50%. It reflects the importance that employees attach to the employment relationship. However, the transactional psychological contract has no significant effect on organizational commitment, and organizational commitment plays a partial mediating role. Therefore, enterprises should focus on building mutual trust and friendly employment relationships and implement targeted management strategies and incentives for employees to enhance their ability of knowledge innovation.
