摘 要: 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。 On the base of the essentials of circular economy and connotations of eco-efficiency, an eco-efficiency index system for assessing the circular economy of Guangdong Province was established with reference to local and international research. By using the established index system, variations in the economy and eco-efficiency for the period from l990 to 2007 were analyzed. The results indicate that Guangdong provincial GDP achieves a high and rapid growth during the last 18 years. Concurrent eco-efficiency indicators and labor productivity display increasing trends for especially the eco-efficiency of total water consumption and construct land. Average annual growth rate of the two indicators respectively reach 21.29% and 17.28%, both are lower than that for GDP. Prediction results from transformed human-environment equation (IPAT) reveal that under present economic growth, strategic objectives for the augmentation of Guangdong provincial economy could be realized by 2015. However, increase in energy consumption and environment load may induce high pressure on the eco-environment.
