【摘要】 通过洛伦兹曲线和基尼系数法分析了粤港澳大湾区城市群的城市土地利用结构,运用基于数据包络分析法构建的投入—产出指标体系评价了粤港澳大湾区城市群及区内11个城市的土地利用效率。结果显示:粤港澳大湾区城市群土地利用效率较高,土地利用类型分布差异较大,区域内城市土地类型分布均衡度随时间推移有所下降;粤港澳大湾区城市群的土地利用效率总体上维持在较高水平,但呈先上升后下降趋势,目前处于城市土地利用规模报酬递增阶段;粤港澳大湾区城市群中经济发达的城市土地利用效率高于经济相对落后的城市,区域内超过一半的城市土地利用效率DEA有效,DEA非有效的城市存在投入冗余和产出不足问题。更多还原

【Abstract】 Using Lorenz Curve and Gini Coefficient Method,the urban land use structure of Guangdong-Hong Kong-Macao Great Bay Area Urban Agglomeration is analyzed.And the input-output index system is constructed by data envelopment analysis to evaluate the land use efficiency of the area and 11 cities in the region. The results show: The urban land use efficiency of Guangdong-Hong Kong-Macao Greater Bay Area Urban Agglomeration is high while distribution of urban land types is quite different; As time goes on,equilibrium degree of regional distribution of urban land types is going down;The land use efficiency of Guangdong-Hong Kong-Macao Great Bay Area Urban Agglomeration firstly rises and then fall over time,but it still remains high and the area is at the stage of scale utility increasing; Urban land use efficiency of economically developed cities is higher than that of relatively backward cities,and more than half of cities in the region are valid DEA;Cities in invalid DEA are facing the dilemma of redundant land input and insufficient output.更多还原
