发展低碳技术是实现各行业低碳转型的有效手段,然而现有研究对具体行业低碳技术的全面追踪较为不足。因此,聚焦关键排放部门建筑行业,采用科学计量和主题建模对其全生命周期低碳技术发展和创新进行评估,基于德温特专利数据库,对检索到的专利族经人工筛选后保留640项,分析其低碳技术的时空分布,得出专利引文网络主路径,动态跟踪技术热点变化与前沿技术,确定其低碳技术发展路径,为行业低碳技术创新发展路线提供具体参考。研究结果表明:① 行业低碳技术创新的专利发明申请数量呈现出激增态势,技术创新主要由全球气候变化和碳减排政策驱动。② 低碳建筑材料是建筑业低碳技术创新的核心领域,是低碳技术发展的热点。③ 建筑清洁能源技术、建筑节能降碳技术、建筑能源系统和智能制造技术等具有发展前景。④ 在运营阶段,可以通过优化建筑能源系统和用户用能行为来驱动建筑的低碳创新行为。

The development of low-carbon technology is an effective means to achieve low-carbon transformation of the industries. However, there are currently more obvious shortcomings in the comprehensive tracking of low carbon technologies in a sector. This study provides a comprehensive assessment of low-carbon technology development and innovation in the construction sector using a scientometric approach and thematic modeling. Using the Derwent Patent Database as the data retrieval source, the patent families retrieved from the search query were subjected to two rounds of rigorous screening, and 640 patent families were retained as a result of the analysis. The development trend and geographical distribution of retained low-carbon technology innovation patents were investigated and analyzed, while the main path of the patent citation network was analyzed to dynamically track the changes in technological hotspots and the identification of cutting-edge technologies,and to determine the low-carbon technology development routes and innovation driving forces, so as to provide a specific reference for the development routes of low-carbon technological innovation in the construction industry. The results of the study show that: ① Patent invention applications for low-carbon technological innovation in the construction industry show a surge in number, and technological innovation is mainly driven by global climate change and carbon emission reduction policies. ② It is found that low-carbon building materials are the core area of low-carbon technological innovation in the construction industry, and it is a hot issue in the development of low-carbon technology.③ It is found that technologies such as building clean energy technologies, building energy-saving and carbon reduction technologies, building energy systems and smart manufacturing technologies are promising. ④ In the building operation stage, low-carbon innovation behaviors in the building sector can be driven by exploring the efficacy of building energy systems in reducing carbon emissions in buildings and optimizing users’ energy use behaviors.
