为降低产业部门间能源消耗,基于投入产出表构建产业部门间间接能源流动网络,结合依赖度矩阵等方法明确产业部门间间接能源流动情况及依赖关系。研究表明:产业部门间间接能源供给较消耗更为集中,供给源头从化工行业转向服务业;产业链上下游环节间间接能源流动量较大且较稳定;间接能源流动与部门间依赖关系的相关性逐渐增强,但仍需改善。需进一步优化产业结构,提高国内产业链完整性,降低产业部门间能源消耗。
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.
