In this paper, we clarify the connotation and composition of the ecosystem of the leisure sports industry and analyse the connotation of the efficiency of the ecosystem of the leisure sports industry. Secondly, the evaluation index system is constructed, and the DEA-SBM model and GML index are used to analyse the time trend and geographical differences of the ecosystem efficiency of leisure sports industry from both static and dynamic perspectives. Next, the six categories of influencing factors of leisure sports industry ecosystem efficiency were sorted out by literature analysis method, and their mechanism of action was analysed. 13 influencing factors were selected for empirical analysis by combining the connotation of leisure sports industry ecosystem and data availability. Finally, the empirical results of efficiency and influencing factors are used to propose paths to improve the efficiency of the ecosystem of leisure sports industry. One public factor is extracted from each of the internal operation system and industrial ecological environment of leisure sports, and the public factor of the internal operation system is named as the internal innovation factor of the industry, and the public factor of the industrial ecological environment is named as the institutional innovation factor, and then the extracted public factors are embedded into the Harken model to identify the sequential covariates that affect the evolutionary development of the ecosystem of leisure sports industry. The research results show that the sequential covariates affecting the evolutionary development of the ecosystem of leisure sports industry are the institutional innovation factors, which means that the leisure sports industry should focus on the role of institutional innovation in promoting the leisure sports industry in the development process, drive the internal innovation of the industry through institutional innovation, cultivate the industrial subjects, stimulate the self-generating ability of the industry, and realize the long-term development of the leisure sports industry.
