Abstract: China's sports development system bears strong particularity and timeliness, i.e. as for China's sports social organizations, at this stage, in their development, gradually is found a new relationship with the government. In the mode of co-production, the government no longer plays the traditional administrative role, acting by the book; instead, it, together with the market and social organizations, bearing flexibility and taking into account efficiency and fairness, creates public value, mutual benefits and common development. The government should relax restrictions on the development of sports social organizations, i.e. to free up more space, so as to render them good assistants of the government in providing better and more responsive sports public services; we should strive to decouple sports social organizations from the government, and shift the focus of sports governance to primary-level social organizations. Meanwhile, sports social organizations, viewed from the perspective of co-production theory, can serve as a channel to orderly transport the human, material and financial resources lacking in competitive sports and market sports so as to promote various sports fields to go hand in hand and exchange needs, thus establishing a modern and efficient sports governance system. Therefore, the perspective of co-production provides a useful analytical framework under which sports social organizations can be treated as a bridge to realize the circulation of social resources, a channel well solving the problem of separation of various affairs in China's sports development, thereby building a sports power and achieving national fitness.
