在“双碳”目标和“京津冀协同发展”的国家战略下,京津冀地区面临经济转型和碳减排的双重压力,能源系统作为平衡经济增长和碳排放的关键纽带,发挥着不容忽视的作用。首先采用投入产出模型厘清了京津冀实体及隐含能源转移网络,其次采用结构路径分析模型识别了京津冀地区能源消费的关键供应链传导路径。研究发现:京津冀地区煤类能源主要依赖山西和内蒙古;部门关联程度较强的部门为“建筑业”“交通运输、仓储及邮政和电信业”;关键的供应链节点大多产生于本地的“金属矿采选业”“交通运输、仓储及邮政和电信业”“批发零售及住宿餐饮业”。研究结论将为京津冀实现能源转型协调发展提供政策建议。

Under the national strategies of “Dual Carbon Goals” and “Coordinated Development of Beijing-Tianjin-Hebei”, the Beijing-Tianjin-Hebei region faces the dual pressures of economic transformation and carbon reduction. The energy system, as a crucial link tobalance economic growth and carbon emissions, plays an indispensable role. Firstly, using an input-output model, the study clarified thetangible and implicit energy transfer networks in the Beijing-Tianjin-Hebei region. Finally, employing a structural path analysis model,the study identified key supply chain transmission paths in the region’s energy consumption. The research findings indicate that the Beijing- Tianjin - Hebei region heavily relies on coal energy from Shanxi and Inner Mongolia. Sectors with strong interconnections include“Construction”, “Transportation, Warehousing, Post, and Telecommunications. ” Critical supply chain nodes are primarily associatedwith local sectors such as “ Metal Ore Mining,” “ Transportation, Warehousing, Post, and Telecommunications,” and “ Wholesale,Retail, Accommodation, and Catering. ” The conclusions of the study will provide policy recommendations for the coordinated developmentand energy transition in the Beijing-Tianjin-Hebei region.
