The rapid development of the digital economy has promoted industrial transformation and upgrading, brought changes to the production mode and personal consumption mode of enterprises, and the development of traditional industries are constantly being realised in a digital format. The research of current scholars mainly focuses on: the calculation of digital economy comprehensive index, it is only scientific interpretation, lack of empirical research; second, the lack of existing research on digital economy indicators, mostly only from a single perspective; and finally, the lack of analysis of regional heterogeneity of digital economy development. Methodology. In the index system weighting method is mainly divided into subjective empowerment and objective empowerment, in terms of subjective empowerment, it is based on the relative importance between the indicators by subjective judgment to give appropriate weight, such as principal component analysis, AHP; and objective empowerment is based on the original information to empower, such as cluster analysis, standard deviation, entropy and extreme method, and so forth. In the selection of measurement method, some scholars believe that the subjective weight method will be disturbed by human factors, which will bias the calculation results, and can not respond to authenticity. In view of this, this paper adopts the entropy method to measure the high-quality economic development level and digital economy development level in 31 provinces in China from 2010 to 2019. The research of current scholars mainly focuses on: the calculation of digital economy comprehensive index, it is only scientific interpretation, lack of empirical research; second, the lack of existing research on digital economy indicators, mostly only from a single perspective; and finally, the lack of analysis of regional heterogeneity of digital economy development. This paper constructs three subsystems and 11 basic indicators to construct the evaluation index of digital economy development, and three subsystems and 9 basic indicators to evaluate the high-quality development of sports industry. To explore the spatial spillover effect of digital economy development on the high-quality development of sports industry, the high-quality development of sports industry in China in 2011-2020 was taken as the explanatory variable, and the development of digital economy was taken as the explanatory variable. The purpose of the article is to build spatial measurement model three subsystems, which include 11 basic indicators to construct the evaluation index of digital economy development, and three subsystems and 9 basic indicators to evaluate the high-quality development of sports industry. The base of research is 31 provinces, municipalities, autonomous regions of China. Conclusion. First, the digital economy is innovation as the core driving force of the new economic form, and the deep fusion of sports industry can give new impetus to the development of high-quality sports industry, further promote the development of the quality of sports industry. Second, digital economy development through advanced digital technology can directly and indirectly promote the development of sports industry, digital economy and sports industry quality development have significant spatial correlation, "high-high", "low-low" agglomeration characteristics, digital economy development can significantly promote the regional sports industry development, and the quality of sports industry development is also obvious.
