有别于传统创新生态系统理论，数字创新在数字创新生态系统中有着核心位置，而现有研究对数字创新生态系统的探讨尚处于初级阶段，急需探究其概念内涵、核心特征和运行机制。为拓展创新生态系统的理论边界，采用文献调研法和理论演绎法，从“数字创新”和“创新生态系统”两个概念解析数字创新生态系统的概念内涵与构成要素，借鉴创新生态系统研究范式从企业微观、产业中观、和国家宏观3个层面构建数字创新生态系统的理论框架。结合数字生态系统和创新生态系统两大理论体系，提出数字创新生态系统的构成六要素包括生产者、消费者、赋能者、运营者、研究者和生态环境，并揭示其具有模块性、适应性、多样性、生长性和共生性五大核心特征。运用概念模型法建构数字创新生态系统的理论模型分析其运行机制发现，数字创新生态系统的稳定演化主要依托于异质性创新资源整合机制、数字化创新能力提升机制、数字价值实现机制和数字协同治理机制4个方面的有序运行来实现。为保障数字创新生态系统的良性运行，应丰富系统内的创新主体类型，并建立面向企业、产业和国家三层次的价值共生协同体系。

Compared with the traditional innovation ecosystem theory, digital innovation has a central position in the digital innovation ecosystem, and existing research on the digital innovation ecosystem is still at a preliminary stage, there is an urgent need to explore its conceptual connotation, core features, and operational mechanisms. To expand the theoretical boundary of the innovation ecosystem, it adopts the literature research method and theoretical deduction method to analyze the conceptual connotation and components of the digital innovation ecosystem from the concepts of "digital innovation" and "innovation ecosystem", and construct the theoretical framework of digital innovation ecosystem from the micro level of the enterprise, the meso level of the industry and the macro level of the country by drawing reference to the paradigm of innovation ecosystem research. Combining the two major theoretical systems of the digital ecosystem and innovation ecosystem, it proposes that the six elements constituting a digital innovation ecosystem include producers, consumers, enablers, operators, researchers, and ecological environments, and reveals that it has five core features: modularity, adaptability, diversity, growth, and symbiosis. Using the conceptual model method to construct a theoretical model of the digital innovation ecosystem to analyze its operation mechanism, it is found that the stable evolution of the digital innovation ecosystem mainly relies on the orderly operation of four aspects, namely, the heterogeneous innovation resources integration mechanism, the digital innovation capacity enhancement mechanism, the digital value realization mechanism, and the digital collaborative governance mechanism. To ensure the healthy operation of the digital innovation ecosystem, the types of innovation subjects within the system should be enriched and a value symbiosis and synergy system should be established for the three levels of enterprises, industries, and the State.
