| The consensus mechanism of the decentralization of blockchain technology has changed the way of social connection,and has caused earth-shaking changes in traditional production relations.The top priority for promoting high-quality economic development and promoting industrial upgrading is to tap and cultivate new economic growth points.Blockchain technology is leading a new round of industrial transformation and is an important driving force for leading the new normal of economic development and promoting industrial upgrading.Patent is the concrete manifestation of original scientific research and technological innovation,and it is also the core and focus of scientific and technological competition and economic competition.Cooperative patent application is an important means for enterprises to improve their own technological level and R&D capabilities.Research on the patent application status of blockchain technology and the structure and evolution of the cooperation network will not only help to identify the current status and trend of blockchain technology development,but also find problems in the process of technical cooperation,and formulate and promote blockchain for the government Provide reference for relevant policies of industrial development,and provide guidance and suggestions for the formulation of patent technology development strategies of related enterprises in the blockchain technology industry.This article is based on the blockchain technology patent data in the Inco Pat patent database and the National Intellectual Property Office patent database(SPIO),combined with the measurement analysis method and the social network analysis method,through the analysis of the development status of the patent,the main application institution,the life cycle,and the technical theme,To explore the current status of blockchain technology development,technology hotspots,and competitive advantage subjects.According to the application of blockchain technology patents,the development of blockchain technology is divided into three stages: the first stage of technology development(2010-2015),the second stage of technology growth(2016-2017),and the third stage.Stage technology rapid development stage(2018-2020),build a total cooperation network and a cooperation network of three development stages,analyze the changes and evolution of the network structure,and compare and analyze the cooperation network within the region of Beijing,Zhejiang,and Guangdong.Evolutionary trends,find out the problems existing in the process of technical cooperation,and provide development suggestions for the development of blockchain technology at the national and enterprise levels based on the analysis results.Research shows that the overall patent applications and cooperation applications of blockchain technology are showing an upward development trend,and it is currently in a stage of rapid technological growth.The technical subjects of the patent application are mainly concentrated in the IPC sub-categories G06Q(electrical digital data processing),H04L(digital information transmission)and G06F(electrical digital data processing).The organizations with competitive advantages are Tencent Technology(Shenzhen)Co.,Ltd.,Alibaba Group Holdings Co.,Ltd.,Ping An Technology(Shenzhen)Co.,Ltd.,Alipay(Hangzhou)Information Technology Co.,Ltd.and other large enterprises.From the perspective of the development of the cooperation network,the State Grid Corporation of China,China Electric Power Research Institute Co.,Ltd.,China Mobile Communications Co.,Ltd.,Beijing University of Posts and Telecommunications and other institutions have strong competitive advantages in the patent cooperation application network.Blockchain technology The scale of the patent cooperation network is gradually expanding,but the speed of establishing the connection relationship between the network entities cannot keep up with the expansion speed of the network scale,the network density is low,and the network connection function is not perfect,indicating the closeness of the connections between the various research and development entities of the blockchain technology It is not high,the depth of cooperation is not enough,and a good cooperation system has not yet been formed. |
