摘　　要：基于新质生产力形成背景,论文以战略性新兴产业中的智能制造、生物医药和绿色环保行业为例,利用截至2023年企业对外投资数据构建中国城市新质生产功能网络,应用社会网络分析方法,开展网络空间结构特征与影响因素研究。研究发现:①与以往城市网络研究相比较,新质生产功能网络未出现明显的“菱形结构”,中高强度联系呈现出以北京为核心的放射型空间特征;②影响因素结果表明,省际边界对三种网络均产生了显著的负向影响,但地理距离的负向作用未发生在智能制造网络中,在中国重大区域高速交通基础设施建设的影响下,地理距离对于要素空间流动的抑制作用相对弱化,但行政壁垒仍然发挥着显著影响;③城市节点属性变量在三个细分网络中影响效应存在差异,体现出不同行业发展尤其是在异地投资的空间选择行为中,对目标城市发展水平与功能特征的针对性要求。研究揭示了新质生产力形成背景下中国城市网络空间结构的变化特征,丰富了城市地理学积极响应国家发展重大战略需求的研究视角,对于完善新发展背景下中国城市体系空间结构演化一般规律的科学认识具有学术意义。Based on the background of the formation of new quality productivity,this study took intelligent manufacturing,biomedicine,and green environmental protection industry in strategic emerging industries as examples,constructed new quality productive function networks by using enterprise foreign investment data up to 2023,and applied the social network analysis method to examine the spatial structure characteristics and influencing factors of urban new quality productive function networks in China.The findings are as follows:1)Compared with previous urban network studies,the networks of new quality productive function do not show a"diamond structure",and the medium and high intensity network links are radiation-type spatial connections with Beijing at the core.2)The results of influencing factor analysis show that provincial boundaries have a negative impact on all three kinds of networks,but the negative effect of spatial distance does not occur in the intelligent manufacturing network.Due to the construction of major regional high-speed transportation infrastructure in China,the impact of spatial distance on intercity investment in new quality productive function networks is relatively weak.However,administrative barriers and the hindrance effect of provincial boundaries still play a significant role.3)The study distinguished the impact of socioeconomic-related variables on the spatial structure of urban networks in the cities where investments are sent and the cities where investments are received,and found that the impact of different variables in these networks are significantly different,reflecting the differences in the development of different industries,especially in the spatial choice behavior of foreign investment.This study revealed the changing characteristics of China's urban network spatial structure in the context of the formation of new quality productivity,which has academic significance for improving the scientific understanding of the general law of the evolution of spatial structure of China's ur
