    摘要:

    采用环境投入产出模型计算长江经济带省际贸易中虚拟水、隐含能及隐含碳流量,进一步结合Spearman等级相关系数研究分地区与分部门间的水-能-碳耦合关系。结果表明:水、能和碳在地区间和部门间均呈显著相关关系,其中第二产业和隐含能-碳相关性最强。虚拟水、隐含能和隐含碳调出调入中,江苏、浙江为关键省份,农业、建筑业和电力、热力、燃气及水的生产供应业是关键部门。深入研究隐含水-能-碳耦合特征,从贸易平衡视角将长江经济带11省市分为3类,发现隐含水-能-碳压力存在从发达地区转入欠发达地区的环境不公平现象。长江经济带应注重关键地区和关键部门节水节能减碳目标落实,推动产业结构低碳化、绿色化发展,同时加快形成区域协同治理体系。

    Abstract:

    Taking the Yangtze River Economic Belt as the research area, this article applies the environmental input-output model to calculate the virtual water consumption, embodied energy consumption and embodied carbon emissions of inter-provincial trade. Combined with the Spearman's rank correlation coefficient, it can explore the water-energy-carbon nexus in different provinces and sectors. The results show that water, energy and carbon present significant consistency in different regions and sectors, among which the secondary industry and embodied energy-carbon have the strongest correlations.In the transfer of virtual water, embodied energy and embodied carbon,Jiangsu, Zhejiang were the hotspot areas, agricultural, construction industry and production and supply of electricity, heat, gas and water were important sectors. To future investigate water-energy-carbon nexus characteristics, the 11 provinces and cities were divided into 3 categories from the perspective of trade balance, which reveals that embodied water-energy-carbon pressure transferred from developed areas to less developed areas unequally. Therefore, the Yangtze River Economic Belt should focus on implementing the goals of water conservation, energy conservation and carbon reduction in key regions and sectors, promote low-carbon and green development of the industrial structure, and accelerate the formation of a regional collaborative governance system.
