摘　　要：基于长三角高新技术企业总部—分支机构数据,采用社会网络分析和空间计量等多种方法,刻画2013—2020年创新网络的演化趋势和结构特征,实证检验产业创新一体化的影响因素。研究发现:(1)长三角城市间产业创新联系日趋增强,中心城市对整个区域的辐射扩散效应不断提升。(2)各城市网络中心度差值显著缩小,核心城市的中介地位逐渐弱化,城市之间的相对差距趋于收敛,多中心的网络空间格局正在形成。(3)产业创新的核心—边缘网络结构突出,空间分异明显。从空间联系演变进程看,产业关联的原有联系强度不断提升,同时更多城市开始探索关联的新方向。(4)基于空间计量模型的实证结果表明,科技创新是推动产业联动发展的关键因素,而技术溢出对产业创新一体化的影响存在不确定性。Based on the headquarters-branch data of high-tech enterprises in Yangtze River Delta, the evolutionary characteristics of the industrial innovation network from 2013 to 2020 are depicted by using various methods such as spatial analysis and social network analysis, and the influencing factors of innovation integration are discussed by using spatial measurement method.The results are as follows:(1) The industrial innovation network has shown a significant expansion trend.(2) the intermediary position of the core city is gradually weakened, the relative gap between cities tends to converge, and a multi-center network pattern is taking shape.( 3) the overall enterprise network presents an core-periphery structure obviously and the spatial differentiation is obvious.(4) empirical study based on spatial measurement found that patent grants is the key factor affecting the connection of urban innovation, while technology spillover has no obvious promoting effect on the innovation links among 41 cities in the Yangtze River Delta.
