中国高端装备制造业的技术关联与扩散效应--基于中国78家高端装备制造业上市公司的专利分析

Chinese High-end Equipment Manufacturing Technological Relatedness and Diffusion Effect: Based on Patent Analysis of 78 Chinese Listed Companies of High-end Equipment Manufacturing Industry

为探究中国高端装备制造业的技术关联和扩散状况,以中国78家高端装备制造业上市公司授权的6 369项专利为研究对象,识别出20个主要技术领域;借鉴投入产出分析法,从专利生产的视角,测算出2006—2015年间各主要技术领域在技术网络中的影响力、感应力、溢出效应和吸收效应4个指标值的变化,进行技术关联和扩散效应分析。研究结果表明,中国应优先发展高端装备制造业的过程和机械控制调节系统方面的技术,并注重加强技术领域间的交流,以提高各技术领域的扩散效应。

The paper explores the technological relatedness and diffusion effect through the input-output analysis from the perspective of patent production, which measures the four indicators, including ＂influence coefficient＂ , ＂induction coefficient＂,＂spillover effect＂ and ＂absorption effect＂ in the technical network tbrmed by the 20 major technical fields identified through 6369 authorized patents held in 78 Chinese listed companies of high-end equipment manufacturing industry. The result shows that it should be given priority to develop the technical field of process and mechanical control system because of its high influence and induction, and strengthen the communication between different technical fields to improve the technological relatedness and diffusion effect.
