城镇土地利用结构效率的数据包络分析

研究目的:如何判断城市土地利用结构的合理性,需要从新的视角并采用新的方法加以研究.研究方法:数据包络分析(DEA)方法.研究结果:(1)沿海城市的用地结构有效性不如内陆城市;(2)不同等级的城市用地结构不合理的用地类型不同;(3)高级别城市土地利用结构效率高于低级别城市和城镇;(4)县级市城区的道路广场用地失调明显.研究结论:判定城市土地利用结构是否合理,必须考虑其历史、社会经济水平,盲目类比国外是不可取的.DEA方法可以较好地定量刻画城镇土地利用结构效率.提出了中国的城镇用地结构的建议标准.

DEA Analysis for the Efficiency of Land Use Structure in Cities and Towns

the purpose of the study is to judge the rationality of urban land use structure from new perspectives and by new methods. Method of DEA was employ ed. The results are: (1) the effectiveness of land use structure in coastal citi es is not as good as that in inland cities (2) inappropriate land use structure in cities of different grades varies (3) the efficiency of land use structure in high-grade cities is higher than that in low-grade cities (4) more land is used for roads and squares in downtown area of counties than needed. Therefore, factors as history, social economic development have to be taken into account to judge if urban land use structure is rational or not. It is inappropriate to co mpare cities in China to cities abroad without considering local conditions. DEA method is a good at assessing the efficiency of land use structure in cities an d towns in a quantitive way. Criteria for land use structure of cities and towns are proposed
