In order to increase the participation rate of community residents in sports services, on the governance concept of a complex system, the networked governance model under sports services has been studied. Firstly, by introducing the background of networked governance, the supply of sports services is selected as the research object. The selected sports service providers are the government, universities, enterprises, associations, and residents. Secondly, the structural model of sports service supply has been constructed. Combining the direct effects model and the intermediary relationship model, the questionnaire is designed. The current situation of sports service supply in the study area is analyzed. Finally, on this basis, the networked governance model strategy has been optimized. The results show that because the age distribution of the subjects is relatively young, the residents in the study area have a higher degree of understanding of sports services. In the direct relationship model and the mediating effect model, the 6 fitting indicators are consistent with the standard values, and no abnormal data appeared. The government, universities, and associations have a significant influence on the supply of sports services. The impact of enterprises and residents on the supply of sports services is not significant. The community environment plays an intermediary role in the supply of residents and sports services, and the supply of enterprises and sports services. Network governance should pay more attention to the participation of multiple subjects, change the leading role of the government, break down the communication barriers between supply subjects, establish an information security mechanism, and build an information sharing system. The research results provide a reference direction for the development of network management in sports services.
