省域经济系统能源与水关联及协同发展研究——基于投入产出和生态网络分析的福建省实证

Energy and Water Nexus and Collaborative Development in Provincial Economic System:Empirical Study in Fujian Based on Input-Output and Ecological Network Analysis

能源与水资源协同发展是省域经济贯彻新发展理念、推动高质量发展的内在要求。基于投入产出分析和生态网络分析方法构建区域关联网络,创建关联度指数评价福建各部门受到能源与水关联影响的压力,同时评价了关联网络的循环性、鲁棒性和控制依赖性。研究发现:能源消费和能耗水呈现部门差异性,而水消费和水耗能呈现部门趋同性;产业结构高级化有助于降低区域整体的能耗和水耗;水关联网络在循环效率和鲁棒性上的表现优于能源关联网络;受关联关系影响较大的部门体现了能源与水之间相互需求较高的特点。最后,从提升资源利用效率和推动跨部门协同升级两个角度提出实现能源与水资源协同发展的对策建议。

The collaborative development of energy and water resources is the internal requirement for the provincial economy to implement the new development concept and promote high-quality development.Based on input-output analysis and ecological network analysis,the regional correlation network is constructed.The correlation index is created to evaluate the comprehensive pressure of each department affected by energy and water nexus,and then the circularity,robustness,control and dependence of the nexus network are evaluated.The findings are as follows:energy consumption and energy-related water consumption are different among sectors,while water consumption and water-related energy consumption are similar among sectors;the upgrading of the industrial structure can help to reduce the energy consumption and water consumption of the region;the performance of water nexus network in cyclic efficiency and robustness are better than those of energy nexus network respectively;the departments which are greatly affected by nexus reflect the characteristics of high mutual demand between energy and water.Finally,some countermeasures are put forward to realize the collaborative development of energy and water from two perspectives of improving the utilization efficiency of resources and promoting the inter-departmental coordination and upgrading.
