Abstract: Under the background of population aging and "Healthy China", health and wellness tourism industry has ushered in unprecedented development opportunities, however, the academic community has not yet reached a consensus on the construction and assessment of the evaluation system of its development level, the identification of key factors and the exploration of innovative paths. Unlike existing studies that often adopt a single perspective, the study constructs the evaluation index system for the development level of health and wellness tourism based on the dual integrated perspective of suitability and competitiveness, and analyzes it using field survey data. The study finds that the interaction of natural factors, community environment, facility factors and product factors jointly affect the development level of health and wellness tourism industry; the key factors affecting the level of development of health and wellness tourism industry are lodging facilities, cultural and artistic products, service level, consumption level, and safety and order; the development of health and wellness tourism industry at a high level is characterized by two groupings, namely "nature-facility driven" and "community-product driven"; the development at a low level is characterized by three groupings, namely "community-facility-product deficient", "nature-community-facility deficient" and "nature-product deficient". Finally, from the industrial chain, value chain, service chain, the study puts forward the "three chains and six dimensions" innovation path: building a "great health and wellness concept", build strategic portfolio advantage, creating composite health and wellness tourism products, scientific and technological empowerment, cultural integration, and returning to its conditions, with a view to providing scientific guidance for the high-quality development of health and wellness tourism industry.

Key words: health and wellness tourism industry, evaluation indicator system, entropy weight method, fuzzy-set qualitative comparative analysis, "three chains and six dimensions" innovation path
