这项工作的目的是探索采矿、矿物加工和金属部门与减缓气候变化技术（CCMT）有关的创新最相关的驱动因素。为此，我们使用基于对数平均Divisia指数的分解分析来分析2001年至2016年期间从世界知识产权组织采矿数据库收集的专利家族的趋势。在最相关的专利局提交的专利族的绝对数量从三个因素的角度进行了分解，即：一国减缓气候变化技术的优先性;一国采矿、矿物加工和金属部门的总体相关性;以及一国专利族的规模。这些因素对不同的国家集团有不同的影响，取决于采矿和矿物部门在其经济中是否发挥重要作用，或取决于它们是发达国家还是发展中国家。我们观察到，分解后的专利趋势与影响采矿和金属行业的重要事件密切相关，例如巴黎协定和金属价格趋势。我们能够得出CCMT在不同国家采矿业发展的结论，并利用这些结论支持鼓励CCMT进一步发展的政策。
The purpose of this work is to explore the most relevant driving factors for innovation in the mining, mineral processing and metals sectors, related to climate change mitigation technology (CCMT). To do so, we use a decomposition analysis based on the logarithmic mean Divisia index to analyze the trends in patent families collected from the World Intellectual Property Organization Mining database between 2001 and 2016. The sheer number of patent families filed in the most relevant patent offices is decomposed from the perspective of three factors, namely: the priority of climate change mitigation technology in a country; the overall relevance of the mining, mineral processing and metals sector in a country; and the size of patent families from a country. These factors have a different impact in different country groups, depending on whether the mining and minerals sector plays a strong role in their economy or not, or whether they are a developed or developing country. We observe that the decomposed patent trend correlates well with important events that affect the mining and metals sector, for example, the Paris Agreement and the price trend of metals. We are able to draw conclusions on how CCMT is developing in the mining sector of different countries and use those conclusions to support policies that encourage the further development of CCMT.
