Abstract Purpose This study aims to provide a new framework for analyzing the path of technology diffusion in the innovation network at the regional level and industrial level respectively, which is conducive to the integration of innovation resources, the coordinated development of innovative subjects, and the improvement of innovation abilities. Design/methodology/approach Based on the Z-Park patent cooperation data, we establish Inter-Enterprise Technology Transfer Network model and apply the concept of Pivotability to describe the key links of technology diffusion and quantify the importance of innovative partnerships. By measuring the topologically structural characteristics in the levels of branch park and the technosphere, this paper demonstrates how technology spreads and promotes overall innovation activities within the innovation network. Findings The results indicate that: (1) Patent cooperation network of the Z-Park displays heterogeneity and the connections between the innovative subjects distribute extremely uneven. (2) Haidian park owns the highest pivotability in the IETTN model, yet the related inter-enterprise patent cooperation is mainly concentrated in its internal, failing to facilitate the technology diffusion across multiple branch parks. (3) Such fields as “electronics and information” and “advanced manufacturing” are prominent in the cross-technosphere cooperation, while fields such as “new energy” and “environmental protection technology” can better promote industrial integration. Research limitations Only the part of the joint patent application is taken into account while establishing the patent cooperation network. The other factors that influence the mechanism of technology diffusion in the innovation network need to be further studied, such as financial capital, market competition, and personnel mobility, etc. Practical implications The findings of this paper will provide useful information and suggestions for the administration and policy-making of high-tech parks. Originality/value The value of this paper is to build a bridge between the massive amount of patent data and the nature of technology diffusion, and to develop a set of tools to analyze the nonlinear relations between innovative subjects.

Z-Park专利合作网络技术转移特征与趋势——基于全球最优路径的视角

摘要 目的 本研究旨在为区域层面和行业层面的创新网络技术扩散路径分析提供新的框架，有利于创新资源整合、创新主体协调发展、提升创新能力。的创新能力。设计/方法/途径 基于Z-Park专利合作数据，建立企业间技术转移网络模型，应用Pivotability的概念来描述技术扩散的关键环节，量化创新伙伴关系的重要性。通过测量分支园区和技术圈层级的拓扑结构特征，本文展示了技术如何在创新网络中传播和促进整体创新活动。结果表明：（1）中关村专利合作网络呈现异质性，创新主体之间的联系分布极不均衡。（2）海淀园区在IETTN模式中具有最高的可转性，但相关的企业间专利合作主要集中在其内部，不利于跨多个分园区的技术扩散。（三）“电子信息”、“先进制造”等领域跨技术合作突出，“新能源”、“环保科技”等领域可以更好地促进产业融合。研究局限 建立专利合作网络时只考虑联合专利申请的部分。影响创新网络中技术扩散机制的其他因素，如金融资本、市场竞争、人员流动等，还有待进一步研究。和高科技园区的政策制定。原创性/价值本文的价值在于在海量专利数据与技术扩散本质之间架起一座桥梁，
