经济增长与电信普遍服务的五阶段模式

在引入米尔恩(Milne)提出的普遍服务五阶段模式的基础上,通过计量技术论证了我国的电信发展与经济增长存在着很强的正向关系,进而得出我国普遍服务发展的五阶段模式。从该模式可知,每个阶段的经济水平、电信水平、电信发展瓶颈都不太一样,所以我国普遍服务的目标、内容和实施措施都应该有所侧重。目前我国的普遍服务对象主要还是农村用户和中西部住宅用户,内容主要是固定电话服务,并不需要涵盖互联网接入服务,而有针对地进行补贴成为主要实施措施。而且这个阶段将会持续很长一段时闯。     

Aerobic Granular Sludge: Perspectives for Excess Sludge Management and Resource Recovery

Aerobic granular sludge (AGS) technology is gaining increasing interest globally. However, several aspects are still challenging its installation, as the integration into existing municipal wastewater treatment plants. The operation of AGS units in continuous flow mode could facilitate that integration; yet has only been experienced at lab and pilot scales. Further, handling of excess granular sludge constitutes a prominent challenge. Even that, adopting effective strategies for its management holds promising contributions to the circular economy by fostering the reuse and recovery of valuable resources. The recovery of phosphorus and alginate-like polymers holds significant commercial potential worldwide, with broad applications in agriculture, food, pharmaceuticals, and biotechnology.

基于AHP-熵权-TOPSIS法对粮仓屋面隔热改造方案的决策分析

采用AHP-熵权- TOPSIS法构建了包含初始投资、运行成本、材料性能、几何与能耗参数在内的评估我国现役粮食平房仓屋面架空层改造综合效益的决策指标体系，进而得到包含总目标、一级指标和二级指标的综合评价模型。以夏季具有湿热气候的赣州地区为例，从经济性、隔热性能、通风能耗和安全性等方面对赣州直属库粮食平房仓屋面架空层改造过程中多种方案进行了分析，采用AHP与熵权法确定各指标的综合权重，评估了赣州直属库粮食平房仓屋面改造综合效益，运用TOPSIS法得出了各方案与理想解的贴近度（0.795、0.563、0.445和0.339）进而确定了最优方案（贴近度0.795）。通过赣州实际工程运行数据验证了该模型在粮食平房仓架空层隔热改造优化研究中的有效性和适用性。     

The COVID-19, power generation and economy – Case study of a developing country

The global COVID-19 pandemic created profound impact on every nation’s economy, education, healthcare, social and cultural life, domestic and international mobility at an unprecedented level. Since the start of the COVID-19 pandemic in early 2020, most nations are undergoing through frequent full or partial lockdowns, resulting in significant economic losses, and unprecedented suffering of hundreds of millions of people worldwide. Given the crucial role of electric power in economic activities, the purpose of this study is to investigate the impact of COVID-19 pandemic on power sector and economy in a developing/emerging country as a case study. The study examined electric power generation and consumption, GDP growth, export, import, remittances, and various government measures undertaken during the COVID-19 pandemic in Bangladesh. Autoregressive distributed lag (ARDL) model was used to investigate correlation between COVID-19 cases and power consumption during full and partial lockdowns. The research revealed a long-run negative relationship between COVID-19 cases and power consumption during partial lockdowns. The study also revealed that the targeted and partial lockdowns accompanied by nation-wide mass vaccination programme can steer the economy along the power sector with minimal or no impact during the COVID-19 pandemic.     

韩国氢经济发展规划

为了应对气候变化,可再生能源在全球方兴未艾。目前,韩国正致力于发展氢能源领域。为创建氢经济发展生态系统,重点是增加氢动力汽车的生产和使用,构建制氢和储运全流程,扩大燃料电池的生产。政府的愿景计划得到了工业企业的大力支持,其中,HyNet联盟计划在2022年前兴建100座加氢站,现代汽车集团宣布“FCEV愿景2030”计划,到2030年投资7.6万亿韩元用于燃料电池系统研发及产能的扩张;POSCO集团计划到2050年建立500万t氢生产体制。如果相关计划顺利实施,预计到2040年,氢气将占到韩国国内能源消耗的5%,经济将增长43万亿韩元,同时创造42万个就业岗位,并大幅减少细颗粒物和温室气体排放。
