从国家和地方政策可以发现，体育产业集聚已成为中国体育产业发展的趋势。 然而体育产业集群作为一个复杂的网络主体，其发展与政府固然分不开，其内部组织结构、关系网络的优化才是集群优化的重点。研究创新构建了“网络特征—主体能力—企业绩效”理论模型，客观地揭示了变量之间的关系，并定量地证明了各变量间的相互作用。统计结果显示：体育产业集群的网络结构和网络关系对企业主体有直接的积极影响。体育企业的主体在网络规模与企业绩效、关系实力和企业绩效、关系质量和企业绩效之间具有明显的中介效应，在网络密度与企业绩效、网络开放性和企业绩效之间不具有中介效应。体育企业的主体获取和利用其他实体的资源并将其应用于生产过程将有助于提高企业绩效，对企业绩效的影响最大。研究对政府和体育企业层面分别提出了规范市场秩序、促进网络建设以及增进知识共享、提高网络质量等管理建议。

From the national and local policies, it can be seen that the sports industry cluster has become the current development trend of China’s sports industry.However，as a complex network subject，the development of sports industry cluster can not be separated from the government，and the optimization of its internal organization structure and relationship network is the focus of cluster optimization.This paper innovatively constructs the theoretical model of “network characteristics-main body ability-enterprise performance”，reveals the relationship among variables objectively and quantitatively.The conclusion is as follows：the network structure and network relationship of sports industrial cluster have direct and positive influence on enterprise main body，and the effect of relationship intensity on enterprise main body is bigger than that of relationship quality and network scale The main body of sports enterprise has intermediary effect between network scale and enterprise performance，relationship strength and enterprise performance，relationship quality and enterprise performance There is no mediating effect between network density and firm performance，network openness and firm performance. Enterprises need to rely on competition and cooperation between upstream and downstream enterprises，to obtain and use other main resources，and use them in the production process，which is conducive to improving enterprise performance.Some management suggestions are put forward，such as standardizing market order，promoting network construction，enhancing knowledge sharing and improving network quality.
