在后发国家新兴产业发展中，创新生态系统的形成与演进扮演着重要角色。但从已有研究来看，后发国家新兴产业创新生态系统发展中的关键机制尚缺乏清晰阐释，尤其是缺乏对创新生态中竞争、合作、共生等主体间多重联动关系的揭示，以及对创新生态系统中科学、技术与市场之间联动机制的系统分析框架。为此，本研究基于中国新兴产业发展实践，探索后发国家新兴产业创新生态系统联动机制的原创性理论，主要包括：（1）构筑科学、技术、市场多层协同的创新生态系统联动分析框架；（2）解析创新生态系统联动机制的主效应；（3）剖析产业异质性在创新生态系统联动机制中的调节效应；（4）分析创新生态系统联动机制中的政策效应。通过综合使用文献、专利、商业多源异构数据，结合机器学习方法，进行纵向多案例与面板数据实证研究。本研究有助于丰富后发国家创新生态系统理论体系，同时也为促进我国新兴产业创新生态系统联动发展提供有针对性的管理与政策建议。

For the development of emerging industries in late-mover countries, the formation and evolution of innovation ecosystem plays a very important role. However, the key mechanism in the development of the ecosystem hasn’t been studied as a discussion of interactions from competitive, cooperative and symbiotic perspectives, and a systematic analysis of the interaction mechanism linking science, technology and the marketplace. Therefore, this research aims to construct an original theoretic framework about the interaction mechanism of the emerging-industry innovation ecosystem in a late-mover country. This research includes four sub-studies: First, this research puts forward a comprehensive analytical framework based on the "science-technology-business" three-layered perspective of the innovation ecosystem. Second, investigating the main effects of the interaction mechanism of emerging-industry innovation ecosystem. Third, analyzing the moderating role of industrial heterogeneity on the interaction mechanism. Fourth, analyzing the policy effect on the interaction mechanism. This research utilizes multiple longitudinal case studies and econometric analysis by using multi-source heterogeneous data and machine learning. This research will contribute to the theoretical understanding of innovation ecosystems in developing countries and provide support crafting policy for China’s catching-up and industry-upgrading strategies.
