国家级高新区间协同创新网络的演化对打造跨区域的高新区协同创新共同体、促进区域协同创新与区域一体化高质量发展具有重要意义.基于2011-2020年国家级高新区内上市企业合作申请专利数据,构建我国东部国家级高新区间协同创新网络,对其结构演化特征开展可视化分析;提出了邻近性、网络依赖性驱动国家级高新区间协同创新网络演化的动力机制假说,并利用时间指数随机图模型(temporal exponential random graph models,TERGM)进行了实证检验.研究发现:东部的国家级高新区间协同创新网络演化呈现多中心与社群化趋势,从以中关村—广州高新区为中心的"双子星"结构,演变为以中关村、上海张江、广州—深圳高新区为多中心的三大社群.在东部的国家级高新区间协同创新网络演化动力机制检验中,邻近性中的地理邻近性具有显著正向影响,而制度邻近性的影响却始终不显著;网络依赖性中的偏好依附性、连通性、传递闭合性均影响显著;协同创新网络演化动力机制具有阶段性转换特征,即由网络形成期的地理邻近性、偏好依附性过渡为网络成长期的连通性与三元闭合性等网络结构层次上的网络依赖性.
Proximity,Network Dependence and the Evolution of Collaborative Innovation Network in the National High-Tech Sector:Take the National High-Tech Zone in Eastern China as An Example
The evolution of the national high-tech zone collaborative innovation network is of great significance to building a cross-regional high-tech zone collaborative innovation community and promoting high-quality development of regional collaborative innovation and integration.This article takes the collaborative innovation network of national high-tech zones as the research object,and based on the cooperative patent application data of listed companies in the na-tional high-tech zones in the east from 2011 to 2020,constructs the collaborative innovation network of national high-tech zones in eastern my country,and its structural evolution conduct visual analysis of features;A hypothesis on the dynamic mechanism that proximity and network dependence drive the evolution of national high-tech interval collaborative innova-tion networks was proposed,and empirically tested using temporal exponential random graph models.The study found that:(1)The national high-tech collaborative innovation network in the east has the characteristics of a"small world",and the network structure shows a multi-center and community evolution trend;from the"twin stars"centered on Zhongguancun-Guangzhou high-tech zone".The network structure has evolved into a multi-center collabora-tive innovation network with three pillars:Zhongguancun,Shanghai Zhangjiang,and Guangzhou-Shenzhen high-tech zone.It initially formed the Bohai rim high-tech zone community with Beijing Zhongguancun as the center,and the Yang-tze River Delta with Shanghai Zhangjiang as the center.high-tech zone community and the Pearl River Delta high-tech zone community centered on the Guangzhou-Shenzhen high-tech zone.(2)In the examination of the dynamic mechanism of the evolution of the national high-tech collaborative innovation network in the east,geographical proximity has a sig-nificant positive impact on the evolution of the national high-tech collaborative innovation network in the east,while the impact of institutional proximity is always not significant;the preference attachment,connectivity,and transitive closure in network dependence all significantly affect the evolution of the national high-tech interval collaborative innovation net-work in the east;the dynamic mechanism of the national high-tech interval collaborative innovation network evolution has staged.The transformation law is the transition from geographical proximity and preference dependence in the network formation stage to network dependence at the network structure level such as connectivity and ternary closure in the net-work growth stage.In addition,the following policy implications are provided for building a national high-tech inter-regional collabora-tive innovation network:(1)Build a national high-tech inter-regional collaborative innovation network mechanism.Stream-line the industrial chain with upstream and downstream linkage and reasonable regional layout,use the industrial chain to lay out the innovation chain,and promote the orderly flow,efficient allocation,and in-depth integration of innovation resource elements in high-tech zones through inter-regional linkage and co-construction and sharing of innovation plat-forms and collaborative centers.Promote the formation and evolution of cross-regional national high-tech collaborative in-novation networks.(2)Rely on the"innovation star"high-tech zones to create more centralized and contiguous na-tional-level high-tech zone innovation communities.Encourage"innovation star"high-tech zones located at the core of the collaborative innovation network to follow market-oriented principles to strengthen innovation collaboration and innova-tion radiation with national-level high-tech zones adjacent or in the same urban agglomeration,explore the establishment of collaborative innovation strategic alliances in high-tech zones,and create more centralized,connected,jointly devel-oped,and cross-regional high-tech zone collaborative innovation communities.(3)Enlarge and strengthen the circle of friends and build a high-quality national high-tech zone collaborative innovation community.Based on the three major na-tional-level high-tech zone innovation communities centered on Beijing Zhongguancun,Shanghai Zhangjiang,and Guang-zhou high-tech zone,it is important to use the multiple connectivity of the high-tech zone's innovative circle of friends and the transitivity of shared partners to strengthen bilateral or multilateral knowledge exchange with technology,reduce the cost and market risk of collaborative innovation in high-tech zones,build a high-tech zone collaborative innovation community that includes more high-tech zones,closer cooperative innovation connections,and a more cohesive innova-tion network structure,and promote high-quality and stable high-tech zone collaborative innovation networks develop.
