基于投入产出法的新能源核心技术和前沿技术研究

Analysis on Core Technologies and Advanced Technologies of New Energy Based on Input-output Method

摘要:

不同于以往运用CITESPACE软件主要依据被引频次、中介性、突现性等指标识别互联网 、智能制造等前沿技术领域和核心技术领域,本文从投入产出分析的视角,以专利为研究对象,即引用其他专利是投入或消耗,而发表的专利是产出,运用投入产出方法进而分析新能源的前沿技术领域和核心技术领域,最后通过敏感性分析,得到新能源各个领域对整体新能源领域的影响程度。本文的专利数据来源于德温特创新专利引文索引(Derwent Innovation Index,DII)专利数据库,利用Python编程语言,提取出每个时间段每种能源领域的专利PN字段和CP字段的专利号信息,并在SQL数据库进行匹配,从而得到一种能源领域引用另外一种能源领域的专利数量。在此基础上构建专利引用矩阵,通过感应力系数、影响力系数和敏感性分析识别核心技术领域、前沿技术领域以及各技术领域对整个新能源领域的敏感性程度,结果表明海洋能源技术是新能源开发和研究的前沿技术,太阳能技术研究属于核心技术领域,太阳能技术领域专利数量变化对整个新能源领域专利变化影响程度最大。

Abstract:

Unlike conventional using software CITESPACE mainly based the cited frequency, intermediate, emergent and other indicators to identify cutting-edge technologies and core technologies in the fields of Internet, intelligent manufacturing and others, in this paper, taking the patent for the study and using input-output analysis method distinguish the advanced technology and the core technology in the field of new energy, which makes the number of cited patents as input, and the number of published patents as output. Patent data for this paper comes from Derwent Innovation Patents Citation Index (DII), using the Python programming language to extract the patent information in PN field and CP field for each time period and each energy sector, then matching this information in SQL database, whereby the number of one energy sector cited from another energy field. Construct the patent citations matrices to identify core technologies filed and cutting-edge technologies field by induction coefficient and influence coefficient, on this basis analyze the degree of sensitivity, to further determine which energy field makes the greater impact for the development of whole new energy field.The results show that the cutting-edge technologies field is marine energy technology research and development,the core technologies field is solar technology field, the solar technology makes the greater impact for the development of whole new energy field.
