摘　　要：创新驱动发展战略背景下,以协同创新引领城市高质量发展具有重要意义。基于2001—2020年中国288个城市联合申请专利数据,利用探索性空间分析法和社会网络分析法,全面考察城市协同创新网络的时空演变特征。结果表明:(1)城市协同创新经历了“低位渐进—稳步增长—快速攀升”的发展阶段,企业参与比例不断下降,但仍是科技创新的主要力量,高校参与比例先上升后下降,“其它”关系占比不断增加,协同创新主体日趋多样化。(2)本地协同创新能力分布极不均衡,呈现“东强西弱、沿海高于内陆”的空间格局;跨界协同创新深度和广度不断拓展,从“一字型”结构向“四面体”结构转变;结合本地/跨界合作强度,将协同创新模式划分为网络密集型、本地优先型、跨界优先型和孤立稀疏型四个类别。(3)城市协同创新整体网络由稀疏型向稠密复杂型转变,呈现明显的小世界性特征;个体网络不断强化,极化现象突出;网络层级渐进生长,“核心—边缘”结构显著。Under the background of innovation-driven development strategy,it is important to guide the highquality development of cities with collaborative innovation.Based on the patent application data of 288 Chinese cities from 2001 to 2020,using exploratory spatial and social network method,this study comprehensively investigates the spatial and temporal evolution of urban collaborative innovation network.The results show that:1)The scale of urban collaborative innovation has experienced the development stage of"low gradual-steady growth-rapid rise",the proportion of enterprises has been decreasing,but it is still the main force of S&T innovation,the proportion of colleges has been increasing and then decreasing.2)The distribution of local co-innovation capacity is extremely imbalanced,revealing the pattern of"strong in the east and weak in the west,and higher in the coast than in the inland";the cross-border co-innovation cooperation is constantly expanding in breadth and depth,and has changed from a"one-line"structure to a"tetrahedron"structure;combined with the intensity of local and cross-border co-innovation,it is divided into four modes:network-intensive,local-prioritized,cross-border-prioritized,and isolated-sparse.3)The overall network of urban collaborative innovation has changed from sparse to dense,with obvious small-world characteristics;the individual network has been continuously strengthened,featuring a prominent polarization;the network hierarchy has grown progressively,showing a significant"core-edge"structure.
