Abstract

A substantial amount of research has examined the collaborations within technology-based industries, but how technological intensity relates to the evolution of interregional research collaboration is less well understood. This paper investigates the dynamic changes of spatial structure and determinants of intercity research collaborations in the sectoral innovation networks of high-tech industries contrasting to low and medium technology (LMT) industries in the Greater Pearl River Delta (GPRD), China. Using the sectoral patent application data over the period 2008–2016, the social network analysis results confirm a higher level of triangles in the co-invention network of high-tech industries than within LMT industries. Moreover, the empirical results through Exponential Random Graph Model (ERGM) show that, compared to LMT industries, collaboration in the co-invention network of high-tech industries is less sensitive to geographical and linguistic distance, while more subject to economic distance, regional educational level and government support with time. In addition, cognitive proximity and regional R&D intensity are both important prerequisite in the formation of these two collaborative networks.

基于产业技术强度的大珠三角城市间共同发明网络演化模式研究

大量的研究考察了基于技术的产业内部的合作，但技术强度与区域间研究合作的演变之间的关系却不太清楚。本文研究了大珠三角高技术产业与中小技术产业部门创新网络中城际科研合作的空间结构动态变化及其影响因素。利用2008-2016年的行业专利申请数据，社会网络分析结果证实，高技术产业的共同发明网络中的三角形水平高于LMT行业。此外，通过指数随机图模型(Exponential Random Graph Model, ERGM)的实证结果表明，与LMT产业相比，高技术产业共同发明网络中的协作对地理和语言距离的敏感性较低，而对经济距离、区域教育水平和政府支持的影响随时间的变化更大。此外，认知接近性和区域研发强度都是这两种协同网络形成的重要前提。
