Abstract In order to reduce the energy consumption between industrial sectors, this paper constructs the indirect energy flow network between industrial sectors based on the input-output table, and defines the energy flow situation and dependence relationship between industrial sectors by combining the dependence matrix with other methods. The results show that, the indirect energy supply is more concentrated than the consumption among industrial sectors, and the supply source shifts from the chemical industry to the service industry. Indirect energy flows between the upstream and downstream links of the industrial chain are relatively large and stable. The correlation between indirect energy flows and inter-sector dependence is gradually increasing, but it still needs to be improved. It is necessary to further optimize the industrial structure, improve the integrity of the domestic industrial chain and reduce the energy consumption among industrial sectors.
