摘　　要：本文从自身投入、内部基础和外部网络3个方面出发,提出了“知识投入–知识结构–知识网络”的三维解释框架,采用2000―2019年InCites数据库收录的世界各国(地区)科学论文数据,探究了全球科学知识生产的时空格局演变与影响因素。研究发现:(1)时序演变上,全球知识生产规模稳步增加,国际合作大势所趋。发达国家科学产出缓慢增长,参与国际合作的意愿强;新兴国家产出规模快速增加,以国内独立研究为主。(2)空间演化上,全球知识生产呈现区域集聚与全局分散的双重特征,重心变迁呈现自西向东转移的趋势,形成西欧、北美和东亚3大热点区域。(3)影响因素上,回归结果表明科学知识生产具有路径依赖和交互式的特征,知识基础、关系资本、结构资本和认知资本均对国家(地区)的知识生产绩效产生积极而又显著的影响。In the context of the knowledge economy,scientific knowledge production increasingly becomes one of the key drivers of long-run economic growth and core competiveness.The scientific knowledge production has been an important topic in economics and economic geography.However,there is a paucity of analysis of the worldwide spatial evolution of scientific knowledge production.On the basis of bibliographical data from the InCites database provided by Clarivate Analytics,this study employs spatial analysis,including geographical concentration index,center of gravity and kernel density analysis,and extended knowledge production function model to investigate the spatialtemporal evolution and influential factors of scientific knowledge production in 2000—2019.Our analyses show that the size of the global knowledge production has expanded,and the number of publications and countries has increased over time.The traditional scientific superpowers have maintained slow growth,while the emerging scientific countries or regions shows a rather fast pattern.The former faces increasing competition from the latter,which may pose a challenge to the Anglo-American academic hegemony and try to create a new world order.The count and percentage of internationally co-authored papers have continued to rise over the past two decades,suggests that international collaboration is increasingly the norm.The established economies have joined the global scientific community,by contrast,the majority of research output remains domestic for emerging counterparts.The geography of the global scientific knowledge production presents the two trends:regional concentration and global spread,and the spatial pattern is evolving from a bipolar world dominated by North America and Europe to a tri-polar world including Europe,North America,and East Asia.The mean center of gravity of global science is moving from the West to the East,which is reshaping the world knowledge production landscape.In addition,empirical results indicate that the knowledge base,rela
