Abstract

[Purpose/significance]By studying the research subject,the author's cooperation and the institution's cooperation,this paper reveals the evolution of Chinese sci-tech informtion field in order to promote the development of this field.[Method/process]Based on CSSCI and PKU core database papers,this paper uses social network analysis,CO-word analysis and visualization methods to conduct keyword clustering,author collaboration network research and institutional cooperation network research in different years,and then get the evolution process of the field.[Result/conclusion]The research shows that the development of Chinese sci-tech information field is in line with the discipline development law.It ranged from theoretical research to applied research,and began to reflect on the construction of disciplines after the development to a certain extent,which is the evolution from quantity to quality.The keynote of the evolution of cooperation network is from decentralization to aggregation.After 2010,two large-scale subnets have been formed,and the degree of cooperation within the subnets has also improved,which is also the inevitable result of the development of disciplines.The evolution of institutional cooperation has changed from low-level and small-scale cooperation to high-level and large-scale cooperation.The evolution changed from the research institute led to the research institute and the university jointly led,and the inter-regional cooperation has evolved into cross-regional cooperation.All these combined effects have promoted the development of sci-tech information field in China.
