【SAM】产业分类 & 元链

基于标普【GICS】行业分类，延伸形成12层级数库【SAM】产业分类体系，包含7000+标准化细分产品节点，90000+元节点上下游关系。呈现产业分类树状层级关系和单节点上下游（生产设备、生产原料、辅助设备、辅助材料、技术服务、销售渠道、应用领域）关系

Based on the S&P GICS industry classification, this dataset extends to form a 12-level industrial classification database system named SAM, which encompasses over 7,000 standardized sub-product nodes and more than 90,000 upstream and downstream relationships between core nodes. It exhibits the tree-like hierarchical structure of the industrial classification, as well as the upstream and downstream relationships of each individual node, including production equipment, production raw materials, auxiliary equipment, auxiliary materials, technical services, sales channels, and application fields.
