Global Cobalt Supply Chain Database全球钴供应链数据库

Overview概览

A relational view of risk in global cobalt supply chain across 22 years (1998–2019). Countries are linked across 6 supply-chain layers (Ore → Material → Product → Use → Waste → Secondary). Supply and demand shocks propagate through the network cascading into “avalanches”, from which systemic fragility (i.e., cruciality) and risk exposure (i.e., vulnerability) of individual states are deducted. The dataset highlights spatial-temporal variation in risk distribution and the interconnected nature of risk against the backdrop of the supply network. We illustrate the dataset from three dimensions: (1) country-level risk profiles; (2) avalanche network structure indicators; (3) fine-grained picture of network community structure.

以关系视角刻画全球钴供应链中的风险，覆盖 22 年（1998–2019）。 各国通过 6 个供应链层级相互连接（矿石 → 材料 → 产品 → 使用 → 废弃 → 二次回收）。 供给与需求冲击在网络中传播，级联形成“雪崩”，由此推断出各国的系统性脆弱性（即关键性） 与风险暴露（即脆弱程度）。该数据集凸显了风险分布的时空差异，以及在供应网络背景下风险的相互关联特征。 我们从三个维度展示该数据集：（1）国家层面的风险画像；（2）雪崩网络结构指标； （3）网络社群结构的精细图景。
