Research on the coupling and coordination of the sports industry and the ecological environment.

Taking Fujian Province, a typical manufacturing cluster region in China, as the case study, we constructed a dual-dimensional eco-industrial index and a dynamic coupling framework tailored for sports-manufacturing-oriented regions. By integrating multi-dimensional spatial analysis methods, we systematically revealed the synergistic mechanisms between the sports industry and the ecological environment. The research findings indicate that regional coordination exhibits a three-stage transition pattern of "scale-efficiency-resilience." Technological investment dominates the scale expansion stage, urbanization quality drives the efficiency transformation period, and the ecological foundation supports resilience reconstruction under external shocks. Geographical barriers result in a fragmented spatial pattern between coastal and inland areas, triggering the implicit transfer of ecological burdens. Industrial chain synergy manifests as the greening of the manufacturing end, reducing the upstream ecological footprint, and functional complementarity at the service end, bridging regional disparities. The study proposes a three-dimensional governance network of "manufacturing-service-ecology," offering a sustainable development paradigm for global manufacturing-intensive regions to promote the deep synergy between ecological civilization and industrial transformation.
