【摘要】：运用物质流、数据包络分析(DEA)及Malmquist指数对中国31个案例城市进行了城市代谢效率的研究。通过将城市代谢系统社会经济产出、环境非期望产出及水、电、化石能源、金属矿物、建筑材料、食物等投入部分纳入进DEA和Malmquist指数中,测得了案例城市的2000年、2010年代谢效率及变化趋势。研究结果发现,中国城市代谢系统效率总体相对较高,尤其是东中部地区城市的综合效率、纯技术效率和规模效率要高于西部地区城市,大城市的代谢综合效率高于巨型、超大和特大城市。2000~2010年,城市代谢综合效率、纯技术效率等所有效率指标的均值均呈现出下降趋势,但是中、西部地区城市的综合效率和纯技术效率却呈改善趋势,并且特大和超大城市的综合效率高于巨型城市。
[Abstract]:The use of the material flow, data envelopment analysis (DEA) and Malmquist index were studied on the efficiency of China City metabolism in 31 case. The city social economic output City metabolic system, environmental undesirable output and water, electricity, fossil energy, minerals, building materials, food and other input into DEA and Malmquist index in the case of the city, measured in 2000, Xie efficiency and change trend of 2010s. The results of the study showed that China City metabolic system overall efficiency is relatively high, especially in the East and central area of the city comprehensive efficiency, pure technical efficiency and scale efficiency is higher than the city of the western region, the comprehensive efficiency of metabolism is higher than that of large and giant city, large city.2000~2010 years, the comprehensive efficiency of city metabolism, mean of all pure technical efficiency and efficiency indicators are showing a downward trend, but in the western region of the city comprehensive efficiency And pure technical efficiency has been improving, and the overall efficiency of mega and super cities is higher than that of mega cities.
