大宗商品价格风险的智能识别与预警基于动态因果知识图谱

Intelligent Identification and Early Warning of Commodity Price RisksBased on Dynamic Causal Knowledge Graph

  • 摘要: 文章报告了一种基于动态因果知识图谱的大宗商品价格风险识别与预警方法。该方法以大连商品交易所交易品种为对象,以产业链上下游企业为 “节点”,以 17 种关联关系(如产业链、参股、资金流等)为 “边”,整合覆盖产业链关系、分支机构、参股等企业关系类型,并详细记录了每家企业的经营范围、地理位置、注册资本等30个属性,形成包含因果逻辑的知识图谱与事理图谱。基于结构因果模型(SCM)、反事实分析等因果推断技术,提炼出三大核心风险指标:产业区域分布(揭示地理集中度与经济联动性)、核心企业分析(识别关键节点及风险传导能力)、价格风险传染路径(量化 “地缘冲突 — 供应链中断 — 价格波动” 等因果链条),通过正负向指标综合评估企业风险等级,实现风险实时预警。研究突破传统统计关联分析局限,解决高维数据伪相关问题,提升风险预警精度。在全球供应链不确定性加剧背景下,为国家战略资源安全保障与企业风险管理提供数据驱动的智能化解决方案,契合 “十四五” 规划强化经济安全风险预警的政策导向。

     

    Abstract: This study introduces a novel method for identifying and forecasting commodity price risks through the construction of dynamic causal knowledge graphs. Focusing on products traded on the Dalian Commodity Exchange, the proposed method models upstream and downstream enterprises along the industrial chain as "nodes", with 17 types of inter-enterprise relationships (e.g., industrial linkage, equity investment, capital flow) represented as "edges". The graph integrates relationship types including industrial chain connections, subsidiary affiliations, and equity holdings, and incorporates 30 attributes for each enterprise—such as business scope, geographic location, and registered capital—to build a causally enriched knowledge and event graph. Through causal identification, including Structural Causal Models (SCMs) and counterfactual analysis, the study derives three key risk indicators: (1) the industrial and regional distribution of relevant commodities (for revealing the spatial clustering and inter-regional economic dependencies of key enterprises); (2) the status of core enterprises (for identifying central nodes and their capacities for risk transmission within the network); and (3) the contagion paths of price risk (for quantifying such causal chains as "geopolitical conflict-supply chain disruption-price volatility", etc.). Enterprise risk levels are comprehensively evaluated using both positive and negative indicators, enabling real-time risk alerts. This approach addresses the limitations of traditional correlation—based statistical models, mitigates spurious associations in high-dimensional data, and significantly enhances early-warning accuracy. In the context of increasing global supply chain uncertainties, the method offers a data-driven, intelligent solution for safeguarding national strategic resources and improving enterprise risk management, in alignment with the 14th Five-Year Plan's emphasis on strengthening economic security and early warning systems.
