Abstract: In order to explore the convergence development trend of sports industry and elderly care industry, this present paper put forward through the methods of documents, entropy and coupled coordination model the industrial level evaluation index of sports industry and elderly care industry, determines the weight of each index and constructs a fusion evaluation model of the two industries. Taking 11 provinces and cities in east China as an example, this present paper measures the development and fusion level of sports industry and elderly care industry, and evaluates the fusion level of sports industry and elderly care industry in the provinces and cities. The study shows that the development level of sports industry and elderly care industry in east China is rising year by year, while the growth rate remains slow. The fusion development of sports industry and elderly care industry in the provinces and cities presents no obvious difference, while the coupled coordination degree is low; and it is common that the fusion degree in the provinces and cities is low. To serve the practice, the paper proposed the countermeasures of continuously improving the comprehensive industrial development level, promoting the fusion development effect of sports industry and elderly care industry, improving the market cultivation function of elderly care industry, and optimizing intercity industrial development strategies.
