Blockchain,as an innovative application model of computer technology,including distributed data storage,peer to peer transmission,consensus mechanism and encryption algorithm,has attracted widespread attention from both domestic and overseas,and has become a hot topic of technological innovation.On the basis of objective literature data of blockchain,this paper analyzed the development stage and trend of literature quantity,discipline distribution structure,research hotspots and tendencies of block chain research,so as to provide reference for further research and development of block chain in china.To make an analysis of current situation and research trend of blockchain research,achieving the purpose of researching on the knowledge network and theoretical structure of blockchain,this paper applied bibliometrics method to analyze the research papers of blockchain in the past eight years in CNKI by means of knowledge mapping generated by citespace.The results showed that the number of blockchain research papers had showing a sudden blowout since 2015.Combining the current policy and economic environment,it was concluded that the studies on blockchain in China were still at the initial stage and the study at present was more found in articles which are introductory or commentary.In the view of knowledge network and structure research,the blockchain research based on the technical subject group consisted of Computer Science,Electronic Information Engineering and automation technology,and the applied subject group consisted of Finance,Energy and Power Engineering,Industrial Manufacturing,Supply Chain Management,Culture Education,etc.These subject structural elements of knowledge shaped the blockchain research,formed three hotpots of technology,application and social macro effects.
