摘　　要：技术、产业的跨界与融合已成为新趋势,区块链技术的分布式数据治理架构为多技术深度联合赋能产业发展提供了新思路,把握区块链产业技术融合结构和发展态势,识别技术发展机会显得尤为重要。本文基于专利数据分析,结合ISI-OST-INPI分类体系,从技术融合的结构、共现矩阵、关联度、动态演化趋势4个层次和角度,探析全球区块链技术的融合态势。研究发现:(1)区块链核心技术主要是电气工程部门的信息技术管理办法、计算机技术、数字通信这3大技术,融合集中度较高;(2)三大核心技术与其他技术融合态势更为明显;(3)技术融合指数维持在较低的水平,区块链技术之间的融合呈现分布不均衡的特征。The cross-border and convergence of technology and industry has become a new trend.The distributed data governance architecture of blockchain technology provides a new idea for multi-technology deep joint to empower in-dustry development,and grasps the technology convergence structure and development trend of blockchain indus-try.It is particularly important to identify opportunities for technological development.Based on patent data analysis and combined with the ISI-OST-INPI classification system,this article explores the global blockchain technology convergence situation from four levels and perspectives:the structure of technology convergence,co-occurrence ma-trix,correlation,and dynamic evolution trend.The study finds that:(1)The core technology of blockchain is three major technologies of information technology management methods,computer technology,and digital commu-nication in the electrical engineering department,with a high degree of convergence and concentration;(2)It is obvious that three core technologies have more convergence with other technologies;(3)The technology conver-gence index is maintained at a low level,and the convergence between blockchain technologies presents an unbal-anced distribution feature.
