Abstract:

Based on the joint patent applications of 41 cities in the Yangtze River Delta Urban Agglomeration from 2004 to 2020, a cross-regional technology collaborative innovation network is constructed, and the temporal exponential random graph model (TERGM) is used to empirically analyze the endogenous and exogenous dynamic factors that promote the evolution of the cross-regional technology collaborative innovation network. The result shows that the evolution of inter-city technological collaborative innovation relationships is the result of a combination of endogenous and exogenous factors. Inter-city technological innovation cooperation tends to be embedded in a triangle structure rather than a star-shaped structure, with prominent “small-world” and “high-agglomeration” characteristics. The evolution of the network has both stability and variability. The higher the level of economic development, advanced industrial structure and openness of cities in the network, the higher the probability of forming innovation cooperation with other cities. The cities with similar human capital levels are more inclined to establish new innovative cooperative relationships. Geographical, institutional, and organizational proximity have positive effects on inter-city technology innovation cooperation. Extending from cross-sectional to vertical dimensions and introducing time-dependent terms for the evolution dynamics of cross-regional technological collaborative innovation network, the findings provide a path reference for the development of regional integrated innovation, as well as a new perspective for the paradigm of social science research in the network economy era.

Key words:

摘要:

以长三角城市41座城市2004~2020年的城际联合申请专利为数据基础,构建跨区域技术协同创新网络,采用时序指数随机图模型(TERGM)实证分析促进跨区域技术协同创新网络演化的动力因素。研究表明:城市间技术协同创新关系的演化是内外生因素共同作用的结果;城市间技术创新合作更倾向于嵌入三角结构而非星型结构,具有突出的“小世界”“高集聚”特征;网络演化过程既有稳定性又有变异性;网络中经济发展、产业结构高级化和对外开放水平越高的城市,与其他城市形成创新合作关系的概率越高;人力资本水平接近的城市更倾向于建立新的合作关系;地理、制度及组织邻近性均对城市间技术创新合作产生积极作用。从截面扩展至纵向维度并引入时间依赖项进行跨区域技术协同创新网络演化动力分析,研究结论为区域一体化创新发展提供了路径参考,同时为网络经济时代社会科学研究范式提供了新的视角。
