Abstract: The development of digital industry clusters in China,under the deep digital-real integration,exhibits a composite advantage characterized by institutional synergy and market-driven dynamics.This is specifically manifested in an institutional framework combining a "new nationwide system" with "market allocation of resources",industrial chain collaboration featuring "robust industrial systems" and "powerful production capabilities",dual-chain empowerment through "complete innovation chains" and "tightly integrated value chains",and a market ecosystem comprising a "unified large market" and "substantial digital infrastructure".Digital industry clusters achieve enhancements in total factor productivity and reconfiguration of value chains within the real economy through technological penetration.However,significant constraints and challenges remain,including systemic weaknesses in the innovation ecosystem that lead to lagging key common technology research and inefficient transformation mechanisms,severe path dependency and inertia in innovation approaches that hinder compatibility between traditional core industries and new business forms,resource misallocation at innovation nodes that diminishes collaborative efficiency among cluster entities,and barriers to data factor circulation and deficiencies in collaborative mechanisms that restrict cross-domain innovation.Therefore,it is imperative to construct an innovation ecosystem that synergizes government guidance with market dominance,implement diversified digital-physical integration strategies to drive the digital transformation of traditional industry models,improve digital chain integration mechanisms to enhance the nodal efficiency of innovation subjects,and establish market-oriented allocation mechanisms for data elements to eliminate collaborative obstacles.Only through these measures can we achieve the innovative development of digital industry clusters where factors and structures are optimally allocated.
