As a sustainable new economic form, digital economy has become an important driving force to promote the integration of culture, sports and tourism industry. Based on the theory of digital economy, this paper uses the theory of industrial integration to analyze and refine the four evolutionary paths of digital economy empowering the integration of culture, sports and tourism industries in Chengdu-Chongqing Economic Circle: digital information empowering Bashu Culture innovation, digital technology accelerating the integration of culture, sports and tourism technology, Internet platforms promoting the expansion of the business of culture, sports and tourism, and new economic models driving the integration of the culture, sports and tourism market and industry innovation. The study concludes that in the process of digital economy empowering the integration of culture, sports and tourism industries in Chengdu-Chongqing region, there are the following realities and challenges: an imbalance in the coordinated development of industrial integration restricts the digital transformation of Bashu Culture, there is an imbalance in the digital technology ethics of urban and rural digital infrastructure, the lack of policy synergy impedes the development of the culture, sports and tourism Internet platform enterprises, and the low degree of enterprise integration restricts the cross-border integration of resources. Based on this, this paper proposes corresponding optimization paths from the levels of cultural integration, technological integration, business integration, and market integration, aiming to promote the high-quality development of culture, sports and tourism industry in Chengdu-Chongqing Economic Circle.
