Chinese modernization provides an important theoretical basis and practical guidance for the high-quality development of China's outdoor sports industry. The outdoor sports industry is not only an important part of meeting people's needs for a better life, but also an important means to promote regional economic development and achieve green and sustainable development. Through the method of literature and logical analysis, it was found that the current development of the China's outdoor sports industry still has problems such as imperfect policies and systems, incomplete industrial chains and unbalanced regional development, insufficient scientific and technological innovation capabilities and product homogeneity, weak outdoor sports cultural foundation and inadequate implementation of the green development concept. Therefore, based on the connotation and requirements of high-quality development, the dynamic mechanism of the development of the outdoor sports industry was systematically sorted out combining theory with practice, including policies, market demand, scientific and technological innovation, culture and values, ecology and other dimensions. On this basis, the path to achieve high-quality development of China's outdoor sports industry was proposed, including optimizing the policy system environment, promoting industrial structure optimization, strengthening scientific and technological innovation drive, cultivating outdoor sports culture, and practicing green development concepts. The study believes that building a scientific and reasonable dynamic mechanism and a systematic implementation path are of great significance for promoting China's outdoor sports industry to move towards high-quality development and helping to achieve Chinese modernization.
