摘　　要：基于中国战略新兴产业综合指数的1109家样本企业及其投资关联企业数据,以城市为基本空间单元,从表征本地化生产的空间集聚和表征流动空间特征的产业网络2个角度刻画战略性新兴产业的空间分布特征,产业网络的异质性以及产业集群规模与产业网络中心性的相互作用。结果表明:1)东部地区核心企业和支撑性企业相对均衡,产业集群较为完善,中部和近西部地区核心企业相对不足,而西北和东北地区企业较少,缺乏集群基础;2)中国战略性新兴产业网络呈现以京津冀、长三角、珠三角和成渝地区为顶点的菱形网络格局,并围绕这些区域的核心城市形成多个垂直联系型产业网络;3)战略性新兴产业网络以研发和信息服务网络和生产制造网络为主,并形成北京、深圳、上海三大国家级枢纽中心,其中北京为研发和信息服务网络的核心节点,而深圳和上海则是生产制造网络的核心节点;4)当产业集群规模较小时,城市在中国战略性新兴产业网络中的枢纽地位以大型核心企业为支撑,当发展到较大规模后,中小型企业是城市的枢纽地位的重要支撑。As an important force to guide future economic and social development,strategic emerging industries are the core of China's modern industrial system that helps in achieving high-quality economic development.The study sample includes 1,109 most representative listed enterprises in strategic emerging industries and their associated 19,540 enterprises.This study has depicted the characteristics of the spatial distribution of China's strategic emerging industries from the perspectives of industrial clustering and industrial networks and provides an in-depth analysis of cluster structure,network centrality,network heterogeneity,and their spatial differentiation.This study has four main findings.First,in the eastern region,the core and supporting enterprises of strategic emerging industries are relatively balanced and the industry clusters are more complete,while in the central and near-western regions,there are relatively few core enterprises and they are mainly concentrated in a few provincial capitals.In the northwest and northeast regions,there are not enough core and supporting enterprises to support the development of strategic emerging industry clusters.Second,China's strategic emerging industry network has a diamond-shaped network pattern with the Beijing-Tianjin-Hebei,Yangtze River Delta,Pearl River Delta,and Chengdu-Chongqing regions at the apex,and several vertically linked industry networks that have been formed by core cities.Third,the core companies'key investments in China's strategic emerging industries are concentrated in three key segments of the industry chain:manufacturing,R&D,and information(20.42%,19.50%,and 17.56%,respectively).Based on this,two major industrial networks-the R&D and information services network and the manufacturing network and three national hubs-Beijing,Shenzhen,and Shanghai,were formed.Beijing is the core node of the R&D and information services network,whereas Shenzhen and Shanghai are the core nodes of the production and manufacturing networks.In addition,Hangzhou is gradual
