Abstract: Leveraging the complex adaptive systems(CAS) theory, this study delves into the formation logic and impact mechanisms of the intricate relationships within Chinese Basketball Association(CBA) clubs. The goal is to elevate the product quality of CBA clubs. We posit that, within the instrumental relationship framework, the core manufacturing entities of clubs—the interactions among managers, coaches, and players—serve as the logical starting point for the evolution of competition product quality. Subsequently, emotional relationships emanating from the interactions imbue competition products with intrinsic vitality and external competitiveness. The rapid development of CBA introduces heightened complexity to its industry environment, notably reflected in the substantial uncertainty of adaptive entities, namely “people”. This complexity is further evident in the development risks and crises of interpersonal relationships, potentially restricting the productivity of labor skills and impacting the quality of club event products. The inverted U-shaped curve of “relationship-behavior motivation” suggests that moderate interpersonal relationships contribute to the efficient operation of the clubs. In response, three strategic dimensions are proposed: macro governance environment guidance to ensure the exercise of power within institutional frameworks; meso-level production environment empowerment to cultivate a “technology+knowledge” dual-engine; micro-level production entity support to enrich players' intrinsic motivation structure. This approach effectively promotes mutual reinforcement between external “institutional advantage-governance efficiency” and internal “relationship-behavior”, thereby enhancing the supply-side product quality of CBA clubs in the new era.
