Methane, an abundant one-carbon（C1） resource, is extensively used in the industrial production of vital fuels and value-added chemicals. However, current industrial methane conversion technologies are energy-and carbon-intensive, mainly due to the high activation energy required to break the inert C–H bond, low selectivity, and problematic side reactions, including CO2emissions and coke deposition. Electrochemical conversion of methane（ECM） using intermittent renewable energy offers an attractive solution, due to its modular reactor design and operational flexibility across a broad spectrum of temperatures and pressures. This review emphasizes conversion pathways of methane in various reaction systems, highlighting the significance and advantages of ECM in facilitating a sustainable artificial carbon cycle. This work provides a comprehensive overview of conventional methane activation mechanisms and delineates the complete pathways of methane conversion in electrolysis contexts. Based on surface/interface chemistry, this work systematically analyzes proposed reaction pathways and corresponding strategies to enhance ECM efficiency towards various target products, including syngas, hydrocarbons, oxygenates, and advanced carbon materials. The discussion also encompasses opportunities and challenges for the ECM process, including insights into ECM pathways, rational electrocatalyst design, establishment of benchmarking protocols, electrolyte engineering, enhancement of CH4conversion rates, and minimization of CO2emission.

老龄化背景下老年人口的多维相对贫困是社会关注的热点,数字经济时代数字普惠金融能否助力减缓老年人口多维相对贫困值得探究。利用中国健康与养老追踪调查和北京大学数字普惠金融指数的数据,实证分析数字普惠金融能否减缓老年人口的多维相对贫困。研究发现,数字普惠金融能够减缓老年人口的多维相对贫困,减贫效应存在个体、家庭以及区域之间的差异。数字普惠金融通过缓解信贷约束、提升投资理财参与度和缩小收入差距三个渠道缓解老年人口的多维相对贫困。鉴于此,应持续推进数字普惠金融发展、建设老龄友好型数字社会、加强老年家庭数字金融反哺和提升老年人口数字金融素养。

利用"一带一路"沿线国家的跨国面板数据,基于SBM-DDF模型的龙伯格生产率指数测算绿色全要素生产率,从金融深化、金融结构与金融效率三个维度衡量金融发展,运用动态GMM方法研究金融发展对绿色全要素生产率的影响机制。结果发现:从长期来看,金融深化与金融结构的优化对绿色全要素生产率存在促进作用,而金融效率的过度提升对绿色全要素生产率存在负面效应。针对绿色全要素生产率的分解项而言,在长期,金融深化与金融结构的优化对技术效率存在促进作用,金融结构的优化对技术进步存在促进作用,而金融深化对技术进步存在负面作用。考虑到区域差异性,将样本分为亚洲与欧洲区域,进一步分析发现:欧洲国家金融结构的优化不论长期还是短期对绿色全要素生产率以及技术进步均存在着正向效应,而在亚洲国家中则没有这种效应;在亚洲国家中,金融效率的提升对绿色全要素生产率的影响是负向的,在欧洲国家中,其影响却是正向的。
