摘要
技术融合已成为推动新兴产业涌现、助力产业结构升级的重要力量。采用技术领域融合力分析指数和社群聚类分析方法,对电子信息、汽车、装备制造产业技术融合的动态演化路径进行了对比分析。基于1985 -2014年三大产业200万专利数据的研究发现:三大产业的技术融合具有明显的“偏好链接”特征,形成少数具有超强架构型融合力和局域型融合力的技术领域;早期的技术融合表现为一系列分散式、小规模的多技术领域交叉渗透,但随后阶段则表现为明星技术领域社群的快速生长,以及它们之间的相互融合;电子信息产业相对于装备制造产业、汽车产业具有更强的偏态分布特征,催生相对少数具有核心地位的基础架构型技术领域和明星技术领域社群。
Technology convergence is a major driving force for emerging sectors and industrial upgrading. Using converging indexes and community analysis, this paper conducts a comparative study on the evolutionary patterns of technology convergence in the IT, automobile, and equipment manufacturing industries. Based on 1985-2014 patent files and their IPC co-occurrence data from the three industries, the results show: there is a clear pattern of preferential attachment which leads to the growth of star technological fields with high level of local and architectural converging force;the early stage is characterized of a number of disparate and small groups of converging technological fields, whereas the later stage is featured with a rapid growth of star communities of technological fields and their blurring boundaries;compared to the automobile and equipment manufacturing industries, the IT industry reveals higher level of skewed distribution that is described by an even fewer architectural technological fields and star communities.
