Abstract

根据循环经济的本质和生态效率的内涵, 在借鉴国内外循环经济研究中所建立的生态效率指标体系的基础上, 构建了度量广东省循环经济发展状况的生态效率指标, 并分析了1990~2007年间广东省经济增长及生态效率要素的变化趋势。结果表明, 广东省GDP在18年间呈快速增长的趋势, 自然输入要素的生态效率和劳动生产率不断上升, 尤其是用水产出率和建设用地产出率, 年均增长率分别达21.29%和17.28%, 但均低于GDP的年均增长速度。人类环境影响方程(IPAT)衍生公式预测结果显示, 如果维持目前经济增长模式, 到2015年广东省可以实现经济发展的战略目标, 但同期的能源消耗和环境负荷将逐年上升, 生态环境压力会越来越大。
