建设用地总量的区域差别化配置研究——以江苏省为例

Analysis on Regional Differentiated Allocation of Construction Land:with Jiangsu Province for Example

在界定建设用地总量区域差别化配置内涵的基础上,建立了由地区生产总值、总人口、建设用地容量、农村建设用地整理潜力4项指标构成的指标体系,采用信息熵求和最大化方法对江苏省13个地级市2020年建设用地总量的区域差别化配置方案进行了测算。研究结果表明:从苏南、苏中、苏北三大区域看,苏南地区建设用地增量占比最大,苏中地区建设用地的需求满足度最高,苏北地区建设用地增量占比最小且需求满足度较低。据此得出以下政策建议:苏南地区应在现有建设用地容量空间内仍然允许其总量适度增长,获得较多的建设用地增量以支撑经济社会快速发展;苏中地区应给予一定量的建设用地总量增长,并积极挖掘现有农村建设用地潜力;苏北地区获得的建设用地增量较少,应重点挖掘农村建设用地潜力,通过城乡建设用地增减挂钩,实现建设用地总量控制目标。

Based on the definition of regional differentiated allocation of construction land and establishment of an indicator system including GDP, total population, construction land capacity and potential of rural construction land consolidation, this paper calculates the construction land of 13 municipalities in Jiangsu Province in 2020 with the method of maximum summation of information entropy. The result shows： from a regional view, the construction land growth of Southern Jiangsu is the largest, the satisfaction degree of demand of Middle Jiangsu is the largest, and the construction land growth and the satisfaction degree of demand of Northern Jiangsu are the lowest. Accordingly we can put forward following suggestions： appropriate growth of construction land within construction land capacity should be allowed in Southern Jiangsu in order to support the rapid development of economy and society ; certain amount growth of construction land should be allocated for Middle Jiangsu with tapping potency of rural construction land consolidation; rural construction land consolidation should be paid attention to in Northern Jiangsu in order to control the amount of construction land.
