摘　　要：基于2007-2020年中国31个省份高新技术产品出口数据,构建“省-国”二模网络,分析各省份对“一带一路”沿线国家高新技术产品出口的时空演变,并使用Tobit模型分析各省份网络地位的影响因素.结果表明:(1)高新技术产品出口规模总体增长、轻微波动,广东、江苏等是高新技术产品出口大省.各省份出口目的地以东南亚国家为主,出口产品类型以计算机与通信技术类为主.(2)高新技术产品出口网络的广度与深度不断拓展,网络呈现出明显的核心-边缘特征,其中东部省份出口比较优势更强.(3)产业集聚水平、外商直接投资、外贸环境、研发创新能力对度数中心度或接近中心度主要产生正向影响,产业集聚水平、外商直接投资、外贸环境、友好城市关系对中间中心度主要产生正向影响.东部和非东部省份的影响因素存在一定的差异性.Based on the high-tech products export data of 31 provinces in China from 2007 to 2020,this paper constructed a"province-country"two-mode network to analyze the spatiotemporal evolution of high-tech products exported from provinces to countries along the Belt and Road,and utilized Tobit model to analyze the factors influencing the network status of provinces.The results show that:(1)There has been a general increase with slight fluctuations in the export scale of high-tech products,with Guangdong Province and Jiangsu Province are the major exporters.The export destinations of each province are mainly Southeast Asian countries,and the export product types are mainly computers and communication technologies.(2)There is a continuing expansion of the breadth and depth,displaying a core-peripheral structure.The eastern provinces have stronger comparative export advantages.(3)Industrial agglomeration level,foreign direct investment,foreign trade environment,and research and development(R&D)capability mainly have positive impacts on the degree centrality or closeness centrality,while industrial agglomeration level,foreign direct investment,foreign trade environment,and friendship city relationship mainly have positive impacts on the betweenness centrality.Furthermore,there are some differences between the influencing factors in eastern and non-eastern provinces.
