"双碳"目标下电动公交充电站优化布局研究

为实现"碳达峰"、"碳中和"的目标,大力发展电动公交车,并建设配套的充电站,已成为我国政府接下来的工作重点.目前对电动公交充电站优化布局的研究,缺乏对定量和定性因素的综合考量.文章将定量的构建数学模型的方法与定性的综合评价的方法相结合,提出了一个新的电动公交充电站优化布局框架体系.首先建立0-1整数规划模型,同时对充电站的选址和服务范围进行决策.接着设计电动公交充电站布局的评价指标体系,使用层次分析法-模糊综合评判法对充电站布局方案进行综合评估.以江阴市公交网络数据进行实证分析,验证了文章提出的方法可以为电动公交充电站布局提供科学、合理的决策支持.

The electric vehicle revolution: Critical material supply chains,trade and development

The emergence of a mass market for electric vehicles (EVs) offers development opportunities for countries that have abundant resources of cobalt, nickel, lithium, copper, aluminium and manganese. Not surprisingly, developing countries have proposed ambitious plans to expand production of these raw materials. However, an observation from the resource curse literature is that strong institutions are required if they are to mitigate the risk of poorly directed, often excessively procyclical, investment, not least because of the complexity, opacity and price volatility of many raw materials utilised by global EV value chains. This paper examines the outlook for EV demand and associated raw material usage paying attention to the drivers and sensitivities required to assess and track future market transformations. These end use shifts are then placed in the context of the broader supply chain adjustments and trends shaping the demand. For resource exporters, adapting to structural change will require fiscal, regulatory, environmental and institution reforms designed to capture shifting patterns of resource wealth in a way which takes appropriate account of comparative advantages in specific value chains and mitigates adverse environmental and social consequences from their extraction and processing.
