Abstract: In order to stimulate the internal vitality of enterprises and obtain market competitive advantages, employee internal entrepreneurship has gradually become an important way to expand the strategic scale of technology-based enterprises. Some scholars in the field of organizational management have found that organizational characteristics, leadership characteristics, and personal factors will affect employees' internal entrepreneurial behavior, but the study of human resource management practice as a whole is still in its infancy. High performance work system, as a complex of enterprise human resource management practices, can promote the development of employees and organizations. Therefore, this study focuses on the influence of high performance work system on employees' internal entrepreneurial behavior and its internal mechanism in technology-based enterprises. Based on social exchange theory and self-determination theory, internal and external work motivation is used as the mediating variable, and the perception of career prospects is used as the moderating variable. Before issuing the questionnaire, this study conducted detailed communication with the principal person in charge before issuing the questionnaire, emphasizing the use and confidentiality of the questionnaire. Finally, 59 valid questionnaires of team leaders and 201 valid questionnaires of members were collected by team leader-member pairing method. The questionnaires used were all existing mature scales to ensure the validity of the questionnaire, and a multi-layer linear model was used to test each hypothesis. The results show that the high performance work system has a positive impact on employees' internal entrepreneurial behavior; intrinsic motivation and extrinsic motivation play a part mediating role in the above relationship. The perception of career prospects not only moderated the relationship between internal and external motivation and internal entrepreneurial behavior, but also moderated the mediating role of high performance work system and internal entrepreneurial behavior. When employees' perception of career prospects is at a high level, the stronger the influence of internal and external motivation on employees' internal entrepreneurial behavior, and the stronger the mediating effect of internal and external motivation between high performance work system and internal entrepreneurial behavior. The research findings are as follows: (1) Technology-based enterprises are more sensitive to innovation and entrepreneurship, and their internal atmosphere and job nature are also more conducive to employee internal entrepreneurship. (2) Intrinsic motivation takes "intrinsic psychological needs" and extrinsic motivation takes "extrinsic opportunity desires" as two different psychological pathways, linking high-performance work systems and employee internal entrepreneurial behavior, forming a transmission mechanism of "high-performance work systems personal motivation employee role external behavior". (3) Under different levels of career prospect perception, the effect of high performance work system on promoting employee internal entrepreneurial behavior is different. Meanwhile, individuals' future situational perception also affects their behavior and attitude. Based on the above discussion, the following suggestions are proposed. First of all, technology-based enterprises should be highly aware of the positive impact of high performance work system on employees' attitudes and behaviors. From employee recruitment, employee training to the construction of employee compensation system can stimulate the enthusiasm of employees. Secondly, technology-based enterprises should give employees more opportunities for growth and rewards, stimulate their internal and external work motivation, and thus promote their internal entrepreneurship. Finally, technology-based enterprises needs to improve its own strategic direction and guarantee the career growth of employees with the stability of the enterprise, so as to enhance employees' perception of career prospects and further strengthen the influence of work motivation on employees' behavior.
