The digital economy provides new opportunities for enhancing the modernization level of industri-al chains in the Chengdu-Chongqing economic circle. Based on the context of the rapid development of the digital economy, this study systematically analyzes the theoretical logic of how the digital economy empowers themodernization of industrial chains from two perspectives: deep integration and collaborative developmentbetween the digital economy and industrial chains. It comprehensively examines the current challenges faced byhe modernization of industrial chains in the Chengdu-Chongqing economic circle, including inadequate digitalinfrastructure , a fragile digital innovation ecosystem, lagging collaborative development of digital industries, andweak capabilities for industrial digital transformation. To fully leverage the enabling role of the digital economy,his study further, analvzes the dvnamic mechanisms driven bv the marketization of data elements as marketmomentum, digital innovation as growth momentum, digital platforms as support momentum, and the integrateddevelopment of digital and real economy as integration momentum. In view of this, in terms of path selection, it isnecessary to consolidate the top-level design for collaborative industrial chain development, enhance digital infrastructure capabilities for industrial chains, reinforce digital platform support for industrial chains, improve theintegration level of the digital and real economy in industrial chains, enhance industrial chain resilience and secu-rity, and optimize the new pattern of collaborative industrial chain development with differentiated positioning.
