Abstract: In the process of market-led development of tech-oriented sports, there is polarization among social participants in tech-oriented sports. From the perspective of social cognitive theory, based on questionnaire survey data from the Shanghai Navigation Model Association, Shanghai Aviation Vehicle Model Sports Association, and 16 district-level youth and children's centers in Shanghai, the impact mechanism of serious leisure and constraint negotiation behaviors are examined through multiple linear regression. The results show that: ①There are differences in the serious leisure characteristics and constraint negotiation behavior of tech-oriented sports pariticipants under different demographic backgrounds, while tech-oriented sports participants show significant differences under demographic control variables such as gender, age, education level, award-winning experience, and participating organization. ②The serious leisure characteristics has a postive predictive effect on constraint negotiation behavior, and social participants in tech-oreinted sports possess serious leisure characteristics and maintain a sustained state of participation through constraint negotiation behaviors.
