Abstract

Recent attention on Sustainable Development Goals (SDGs) has spurred investigations into green innovation, pivotal for sustainable industry transformation through green patents. Yet, the green innovation performance lacked a more comprehensive measurement with both internal and external criteria; meanwhile, the nexus between green innovation and SDGs remains underexplored in the construction sector. This study pioneers a comprehensive framework to measure green innovation performances by citation-based analysis and to uncover their potential impacts on the achievement of the 17 SDGs by content analysis across 1.8 million patents, identifying 61,951 as green patents by three classification methods. Based on the construction of citation network, results show 79.64 % of citations within single domains, with mere 1.34 % integrating non-construction knowledge, signaling limited novelty. The similarity analysis has been conducted based on contents between novel green patents and 17 individual SDGs. Emphasis on specific SDGs varies, notably on SDGs 13 (climate action), 16 (peace, justice, and strong institutions), 5 (gender equality), and 9 (industry, innovation, and infrastructure), while SDGs 3, 4, 7, and 11 relating to health and well-being, quality education, affordable and clean energy, and sustainable cities and communities receive less attention. These findings underscore the need for enhanced cross-domain collaborations and a refined classification system to achieve a more balanced contribution across SDGs, promoting sustainable construction.

为更绿色的未来而创新：绿色专利的新颖性及其对中国建筑行业可持续发展目标的影响

最近，人们对可持续发展目标（SDGs）的关注激发了对绿色创新的研究，而绿色创新是通过绿色专利实现可持续产业转型的关键。然而，绿色创新绩效缺乏更全面的衡量标准，既包括内部标准，也包括外部标准；同时，在建筑领域，绿色创新与可持续发展目标之间的关系仍未得到充分探索。本研究开创性地建立了一个综合框架，通过引文分析来衡量绿色创新绩效，并通过对 180 万项专利的内容分析来揭示其对实现 17 个可持续发展目标的潜在影响，通过三种分类方法识别出 61951 项绿色专利。在构建引文网络的基础上，结果显示79.64%的引文属于单一领域，仅有1.34%的引文整合了非构造知识，表明新颖性有限。根据新型绿色专利与 17 个可持续发展目标之间的内容进行了相似性分析。对具体可持续发展目标的重视程度各不相同，尤其是可持续发展目标 13（气候行动）、16（和平、正义和强有力的机构）、5（性别平等）和 9（工业、创新和基础设施），而与健康和福祉、优质教育、负担得起的清洁能源以及可持续城市和社区相关的可持续发展目标 3、4、7 和 11 则较少受到关注。这些发现强调了加强跨领域合作和完善分类系统的必要性，以便在可持续发展目标中做出更加均衡的贡献，促进可持续建设。

期刊介绍： The journal Resources, Conservation & Recycling welcomes contributions from research, which consider sustainable management and conservation of resources. The journal prioritizes understanding the transformation processes crucial for transitioning toward more sustainable production and consumption systems. It highlights technological, economic, institutional, and policy aspects related to specific resource management practices such as conservation, recycling, and resource substitution, as well as broader strategies like improving resource productivity and restructuring production and consumption patterns. Contributions may address regional, national, or international scales and can range from individual resources or technologies to entire sectors or systems. Authors are encouraged to explore scientific and methodological issues alongside practical, environmental, and economic implications. However, manuscripts focusing solely on laboratory experiments without discussing their broader implications will not be considered for publication in the journal.
