Abstract: Based on literatures on innovation ecosystem, this paper attempts to straighten up the difference and relation between researches under multiple levels. Paying close attentions to "interdependence between the subjects" emphasized by innovation systems theory and "the subjects’ interaction with the environment" emphasized by ecology, it establishes that a “Core-Periphery” fame to contain the components of innovation ecosystem. By analysising the changes of subjects’ (central) and environment’s (peripheral) scopes on micro meso and macro levels, this paper reveals the connotations, structure and behavior that innovation ecosystem on different levels contained, and the cross-level interactions. At last, some recommendations are made for the studies and practices.

摘要： 以综述大量创新生态系统研究文献为基础，试图理顺不同层次相关研究的区别和联系；紧扣创新系统理论强调的“主体之间相互依赖”和生态学强调的“主体与环境的相互作用”，将创新生态系统的各类组成要素统一到一个“中心—外围”的结构分析框架之中；通过分析微观、中观和宏观三个层次创新主体（中心）和环境（外围）范畴的变化，揭示出不同层次的内涵、结构和行为，以及各层次之间的相互作用。以此基础上为其理论研究和实践发展提出三点启示。
