Since the 1990s, sport policy research has gradually attracted increasing academic attention as a reflection of contemporary society at a particular time. This study adopted four types of theory proposed by Houlihan (2014) to analyze the research development of sport policy. It conducted a systematic review and yielded 100 policy articles related to elite sports, physical education, and sport for all. The scope of the research data was identified from 2000 to 2020 with collation from 24 international Social Science Citation Index (SSCI) journals, which specialized in policy and sport–related studies of social science to look forward to a comprehensive report. The four major findings were as follows: first, this study pointed to evidence that nearly half the research on the topic aimed at meso–level analyses of organizations; second, it demonstrated governance theory, the Sports Policy Factors Leading to International Sporting Success (SPLISS) model, the advocacy coalition Framework (ACF), and network-related theories played a pivotal role in focusing on policy backgrounds and dynamic relationships within organizations; third, it identified some studies highlighted in the policy texts themselves, or discourse about them, and, thereby, were grouped into the fifth type; finally, the paper suggested that attention has been brought to policy formation and implementation rather than policy evaluation, which has made a contribution to the development of their own operating mechanisms.
