摘要
基于多尺度投入产出法,核算了广东省各部门水资源能源粮食要素的资源强度,对贸易视角下水资源、能源、粮食3类资源的压力互馈情况进行量化分析。结果表明:2007—2017年,广东省区域经济系统各部门的水资源能源粮食资源强度逐年下降,利用效率逐步提升,水、粮食强度值较高的部门集中于水的生产和供应业、农业等资源密集型部门,能源强度值则以矿业、电力及燃气的生产和供应业较高;各部门吸纳了大量的水资源能源粮食资源净流入广东省经济系统,且主要由制造业进入,城镇居民消费和省外调出是水资源能源粮食的主要最终消费途径;广东省本地资源使用压力因水资源能源粮食资源贸易流通而得到显著改善,能源贸易缓解了本地84.33%的能源使用压力,粮食贸易缓解了本地40.13%的粮食使用压力,粮食贸易对水资源压力的缓解作用达能源贸易的5倍。
With active resource trade in Guangdong Province,the relationship between water,energy,and food consumption is complicated,which makes comprehensive resource management difficult.Therefore,it is necessary to accurately calculate resource utilization efficiency and quantify resource interaction pressure from the perspective of trade.Based on the multi-scale input-output method,this study calculated the resource intensity of water-energy-food in Guangdong Province,quantified the circulation of water-energy-food-related resource elements,and conducted a quantitative analysis of the mutual interplay of water-energy-food resource pressures from the perspective of trade.The results show that,from 2007 to 2017,the water-energy-food resource intensity in all sectors in Guangdong Province gradually decreased,and the utilization efficiency gradually increased.High water and food intensity were concentrated in resource-intensive sectors such as the water production and supply industry and agriculture,while the energy intensity was higher in sectors such as mining,electricity,and gas production and supply.Various sectors absorbed a large amount of water-energy-food resources into the Guangdong economic system,mainly from the manufacturing industry.Urban consumption and out-of-province transfers were the main final consumption outlets for water-energy-food resources.The pressure on local resource use in Guangdong Province has improved significantly because of water-energy-food resource trade circulation.Energy trade has relieved 84.33% of the pressure on local energy use,and food trade had relieved 40.13% of the pressure on food use.The water pressure relief effect of food trade was five times that of energy trade.
