Research on the resilience of petroleum industry chain and supply chain network from the perspective of China

The security situation of the global petroleum industry chain and supply chain network has undergone significant changes, especially during events such as the pneumonia pandemic. As a country with significant changes in the petroleum industry and supply chain, studying China is of great significance. At the same time, the overall research on the security of the petroleum industry chain and supply chain is not yet complete. Therefore, starting from node resilience and structural resilience, this study constructs a research system for preparation, stability, resistance, and reconstruction, which can comprehensively study the security of the petroleum industry chain and supply chain. Research has found that: (1) The central countries of the petroleum industry chain and supply chain are relatively fixed, concentrated in countries such as the United States, China, the Netherlands, and Canada. (2) The petroleum industry chain and supply chain network are all heterogeneous networks , and there are significant differences in the countries in the network. (3) In the supply chain network of the petroleum industry chain, the efficiency of the network will sharply decrease before the ratio of node to edge losses reaches a certain value. (4) In the petroleum industry chain and supply chain network, countries located at the hub will prioritize recovery. Research is of great significance for maintaining the security of the petroleum industry chain and supply chain.
