Abstract:We use the blockchain patent documents included in the PatSnap patent database as the data source and use the patent bibliometrics method to analyze patent data onto multiple dimensions of time, region, and patentee, which can reveal the development trend of blockchain technology and mine typical blockchain institutions and high-value patents. In addition, the social network analysis software UCINET is utilized to analyze the key technologies of blockchain at home and abroad and the development of my country's blockchain technology. The research found that blockchain technology is in a period of rapid development, China and the United States are the leaders of blockchain technology. China's blockchain industry is mainly concentrated on developed provinces such as Guangdong and Beijing. Although it has scale advantages in the world, there are still a certain gap in patent quality compared with the United States, and it may face the risk of "stuck necks" in the future. Finally, it is proposed to do a good job in the top-level design of the blockchain industry technology from the government level, accelerate the integration and development of the blockchain and other industries from the industrial level, support the demonstration applications in areas with good foundations from the regional level, and encourage enterprises to increase R&D investment and development to create competitive products from the enterprise level.
