研究目的:介绍DEA模型在土地利用结构效率分析中的应用,分析城市土地利用结构效率的特点及与城市规模之间的关系,为中国城市合理的土地利用结构及其调整方向提供借鉴。研究方法:采用DEA(数据包络法)进行相关系数的计算,通过概率的基本原理挖掘多目标的信息。研究结果:(1)整体上中国城市土地利用结构效率偏低,规模收益报酬处于递减状态,不同等级的城市表现出完全不同的相对效率和规模收益报酬递增,减规律。(2)不同土地利用类型对相对效率的影响差异较大,并在不同等级的城市内表现出不同的影响强度和个性。研究结论:不同等级的城市存在相对合理的土地利用结构状态。
The purpose of this study is to provide reference to rational adjustment of urban land use structure by applying the DEA model in urban land use structure analysis. The characteristics of urban land use structure and its relations to urban areas were analyzed. Methods of DEA and probability were employed. The results indicate that land use structure efficiency (LUSE) is low on the whole and cities with different grades show diverse efficiency and the return to scale profit. The influence of land use types on relative efficiency varies a lot and show different intensities and characteristic in cities with different grades. It is concluded that there exists relatively reasonable land use structure in cities with different grades.
