Abstract: The frequent occurrence of chaos and safety accidents in sporting events reveals the imbalance between order and vitality in the regulation of sports events. Based on the literature and logical analysis, the actors, objects, content, legislation, and tools of sports events supervision are analyzed. It is found that there were problems such as unclear boundaries of government departments, weak supervision capacity of individual sports associations, vague definition of supervision object and content, imperfect supervision system and inappropriate use of the laws and regulations. In order to solve the operational dilemma and deep-seated problems in China's sports events supervision system, the general idea of constructing and improving China's sports event supervision system is proposed: at the core value level, the basic principle of the reform of "delegating, control and serving" of sports events should be adopted; at the central transmission level, the vertical integration and horizontal coordination of supervision subjects should be strengthened; and at the level of supervision mechanism and service system, a digital platform for sports events supervision should be constructed. On this basis, the main countermeasures for the construction of an improved supervision system of sports events in China are proposed: improving the supervision system and legal system, clarifying the supervision content and matters, and constructing integrity system for sports events.
