摘　　要：随着应用领域的不断扩展,区块链技术受到全社会的广泛关注。本文采用赫芬达尔-赫希曼指数和熵指数两种方法对我国区块链技术专利权人、各分支领域、各省市地区的专利集中度进行测算分析。结果表明,我国区块链技术专利权人的专利总体呈现分散趋势,但区块链技术分支领域的专利集中度差异明显,其中数据层和应用层技术的专利较分散,激励层技术的专利较集中。各省市地区的区块链技术专利集中度各有不同,东部地区的专利较分散,但西部地区的专利较集中。针对分析结论提出,政府应因地制宜出台政策避免专利过度集中与分散,其中东部地区促进形成专利池,整合区块链技术资源,西部地区加强专利成果的转移转化,促进技术流入市场;企业应在激励层技术上寻找突破点加大研发力度,并在数据层和应用层领域适当促进专利集中;高校、科研院所与企业联合研发,建立合作共享的技术创新体系。With the continuous expansion of application fields,blockchain technology has received extensive attention from the whole society.This paper uses the Herfindahl-Hirschman index and the entropy index to measure and analyze the patent concentration of China’s blockchain technology patent holders,various branches,and provinces.The results show that China’s blockchain technology patents are generally decentralized,but the concentration degrees of patents in the branches of blockchain technology are significantly different.Among them,the patents of data layer and application layer technologies are more scattered,and the patents of incentive layer technologies are more concentrated.The concentration degrees of blockchain technology patents in various provinces and cities are different.The patents in the eastern region are more scattered,but the patents in the western region are more concentrated.In response to the conclusions of the analysis,the government should introduce policies to avoid excessive concentration and decentralization of patents.Among them,the eastern region should promote the formation of patent pools,integrate blockchain technology resources,and the western region should strengthen the transfer and transformation of patent results,and promote technology to flow toward the market.Companies should make breakthroughs in incentive layer technology to increase R&D efforts,and appropriately promote patent concentration in the data layer and application layer.Universities,research institutes and enterprises should jointly conduct research and establish a cooperative and sharing technological innovation system.
