体育产业结构优化与体育产业高质量发展存在内在逻辑关联，深入分析两者的动态演化情况，对促进两者协调具有重要的现实意义。运用熵值法和耦合协调度模型，在分析我国体育产业2015—2022年的相关统计数据的基础上，对体育产业结构优化水平与体育产业高质量发展水平的动态演化规律进行实证分析，结果显示：1）我国体育产业高质量发展水平在研究期内呈现出规模持续扩大、发展动力持续增强、生产效率不断提高及产业效益持续提高的特点，并且发展动力在驱动体育产业高质量发展方面的作用愈加突出；2）我国体育产业结构优化与体育产业高质量发展之间的协调程度是不断变化的，两者提高水平在体育产业发展过程中会出现不同程度的波动，甚至会出现相互制约的情况；3）从2020年开始，我国体育产业结构优化水平显著下降，但是与体育产业高质量发展的耦合协调水平有所提高，耦合协调水平持续处于“初级协调”状态，耦合协调程度则由2019年的“过渡协调”转变为“基本协调”。结论： 从研究期而言，我国体育产业结构还不够合理、体育产业内部细分产业产出结构不够均衡并且协同发展程度不足，与我国体育产业整体结构最优化仍有差距；从时序演化角度来看，我国体育产业结构优化与体育产业高质量发展之间的协调程度是不断变化的，但是是符合经济发展规律的。因此，今后应当进一步探索使体育产业结构优化与体育产业高质量发展耦合协调的路径，推动体育产业内部细分产业协同发展。

There is an inherent logical connection between the industrial structure optimization and high-quali-ty development of sports industry. An in-depth analysis of theirdynamic evolution is of great practical significance for promoting their coordination.Using entropy weight method and coupling coordination degree model, based on the analysis of relevant statistical data of China’s sports industry from 2015-2022, this study empirically analyzes the dynamic evolution law between the level of structural optimization and the level of high-quality development of the sports industry. The results show that: 1) During the research period, the high-quality development level of China’s sports industry was characterized by continuous expansion of scale, sustained enhancement of development momentum, steady improvement of production efficiency, and consistent growth of industrial benefits, with development momentum playing an increasingly prominent role in driving high-quality development; 2) The coordination degree between the structural optimization and high-quality development of China’s sports industry was constantly changing, and the improvement levels of both exhibited fluctuations of varying degrees during the industrial development process, and even mutual constraints occurred; 3) Starting from 2020, the structural optimization level of China’s sports industry decreased significantly, while the coupling coordination level with high-quality development improved to a certain extentremaining in the state of“primary coordination”since then, and the coupling coordination degree shifted from “transitional coordination” in 2019 to“basic coordination”. Conclusions: During the research period, the structure of China’s sports industry was still unreasonable, the output structure of internal sub-sectors in the sports industry was insufficiently balanced, the coordinated development level among internal sub-sectors was inadequate, and there was still a gap from the optimal overall structure of China’s sports industry; from the perspective of temporal evolution, the coordination degree between the structural optimization and high-quality development of China’s sports industry was constantly changing but in line with the laws of economic development. Therefore, future efforts should further explore the paths for the coupling and coordination of sports industry’s structural optimization and high-quality development, so as to promote the coordinated development of sub-sectors within the sports industry.
