摘　　要：利用投入产出模型对广东省三大产业生态足迹进行评估。结果表明广东省2002年到2017年的人均生态足迹显现出增长趋势,第二产业的人均生态足迹大于第一产业和第三产业;广东省产业投入产出效率整体呈现升高特征,第一产业单位产出所消耗的土地面积最大,第三产业最少;在2002年到2017年间,广东省的生态足迹贸易逐渐达到平衡。因此,为了保护生态环境和促进社会经济可持续发展,广东省有必要优化产业结构(例如,大力发展现代农业,提高第一产业的土地利用效率),加强环境治理。Ecological footprints of industrial sectors were evaluated based on input-output model from Guangdong Province.The result showed that the per capita ecological footprint of Guangdong Province is increasing.In addition,the per capita ecological footprint of the secondary industry was greater than the footprint of the primary and tertiary industries.The industrial input-output efficiency in Guangdong Province increased from 2002 to 2017.Compared with other industrial sectors,ecological footprint per unit output in the primary industry was the largest.Conversely,ecological footprint per unit output in the tertiary industry was the least,and the trade of ecological footprint showed the features of deficit and balance in 2002 and 2017 respectively.Therefore,in order to promote ecological efficiency,strategies for optimizing industrial structure(i.e.,encouraging modern agriculture and service industries)should receive more attention.
