网络视角下战略性新兴产业技术创新小生境演化研究

运用生态学小生境理论分析新兴技术演化和产业技术创新问题是当前的研究焦点。基于网络视角，通过引入期望机制、力量机制和知识机制3个指标维度，将技术创新小生境划分为缺失期、萌发期、胚胎期、原型期、成长期和成熟期6个演化阶段。选取我国内地27个省市自治区新能源汽车产业相关数据，采用社会网络分析法进行实证分析。在确定各地区技术创新小生境演化阶段的同时，归纳出3种技术创新小生境模式，分别为关键技术主导型、科技孵化支撑型和集成创新驱动型。通过进一步对核心技术演化过程进行分析，发现主导、竞争、共生构成了核心技术演化态势。最后，提出了完善自我保护机制、构建协同共生模式和优化创新生存因子的相关政策与建议。

Research on Evolution of Technological Innovation Niche of Strategic Emerging Industry from the Perspective of Network

Using the theory of niche to analyze the evolution of emerging technology and industrial technology innovation is the focus of current research. From the perspective of network, taking the new energy vehicle industry as a study object, the technological innovation niche are divided into six evolutional stages such as stages of absence, germination, embryonic, proto-niche, growing and full through measuring indicators of three dimensions which are expectation mechanism, power mechanism and knowledge mechanism. We select relevant data of new energy vehicle industry from main 27 provinces, autonomous regions and municipalities and identify the evolutional stages by using Social Network Analysis. Meanwhile, we sum up three models which are key technology leading model, technology incubator supporting model and integrated innovation driven model. Furthermore, through analyzing the evolution of core technology, we find that the development status of core technology consists of predominance, competition and symbiosis. Finally, some optimization strategies are put forward from three aspects which are improving self-protection mechanism, constructing cooperative symbiosis model and optimizing survival factors of innovation.
