建筑业低碳技术创新图谱分析及政策启示

A Scientometric Analysis of Low-carbon Technology Innovations in Construction Industry and Its Political Implications

摘要:

目前资源短缺、气候变化、环境污染等问题日益严峻，建筑业的低碳技术创新迫在眉睫。以德温特专利数据库（ Derwent Innovations Index，DII ）为数据来源，运用信息可视化软件CiteSpace对建筑业的低碳技术进行时空分布分析，并通过词频探测技术识别出热点领域和前沿方向。图谱分析结论表明：建筑围护结构低碳技术是所有研究热点中关注度最高的，而建筑材料低碳技术则是未来最具潜力的前沿方向。结合国内建筑业低碳技术创新发展的现状，从机制构建的角度提出相应的政策启示：完善低碳技术发展的政府引导机制、建立碳税与碳排放交易机制、强化公众参与监督机制和构建低碳技术国际交流合作机制。

Abstract:

Currently，the problems of energy shortage, environment pollution and global warming have become increasingly severe, and hence the low-carbon technology innovations of construction industry are extremely urgent．Targeting low-carbon technologies in construction industry , this study employs CiteSpace to analyze the related patents included in Derwent Innovations Index (DII), shows the research temporal and spatial distributions, and identifies hot spots and front edges through the frequency detection method. The scientometric map indicates that the low-carbon technologies of building envelope structure occupy the highest attention, whereas the low-carbon technologies of building materials are the most promising front edges in the future. Considering the current state of low-carbon technology innovations in China’s construction industry, we put forward policy enlightenments from the perspective of mechanism construction, namely improving the government guiding mechanism for the development of low-carbon technologies, establishing carbon tax and trading mechanism, strengthening public participation and supervisory mechanism, and constructing international exchange and cooperation mechanism.
