基于要素贡献率的建设用地差别化管理——以武汉城市圈为例

Study on Differentiated Management of Construction Land Based on Factor Contribution Rate: Taking Wuhan Urban Agglomeration for Example

利用武汉城市圈2001—2012年39个县区的面板数据和拓展的C-D生产函数,对城市圈建设用地对经济增长的贡献率进行了估算,并结合要素贡献率和建设用地集约水平划分建设用地管控区,提出了总量控制和差别化调控的建设用地管理模式。结果表明:1武汉城市圈土地、资本、劳动要素对经济增长的贡献率分别为6.07%、17.68%、62.18%,建设用地对经济增长依然有着重要作用且暂时很难被资金和劳动有效替代;2城市圈各县区建设用地对经济增长的贡献率存在明显差异,最高为50.36%,最低仅为0.66%;3按照要素贡献率和建设用地集约水平,可将城市圈建设用地划分为优先供给区、重点供给区、适度供给区、内涵挖潜区四个管控区;4建设用地差别化管理可在管控区的基础上进行设计,通过总量控制和差别化调控两方面实现。

In this paper, the contribution rate of construction land in urban agglomeration to the economic growth is estimated by using the panel data and extending C- D production function of 39 county units in Wuhan Urban Agglomeration from 2001 to 2012. Considering the factor contribution rate and the construction land intensive level, this paper divided the management control area of construction land and on this basis put forward the differentiated management mode of total amount control and differentiated control. The results show that（1） the contribution rate of construction land, capital and labor is 6.07%, 17.68% and 62.18% respectively, and the investment of land has a significant contribution to Wuhan Urban Agglomeration＇s economic growth, and is temporarily difficult to be effectively replaced by capital and labor;（2） there are obvious differences in the contribution rates of the 39 county units in Wuhan Urban Agglomeration, with the highest being 45.54% and the lowest being only 0.30%;（3） according to the factor contribution rate and the intensive use level of construction land, Wuhan Urban Agglomeration was divided into four types of control areas, namely the priority supply area, key supply area, moderate supply area and potential excavation area;（4） in order to make the policy more operable and practical, the differentiated management of construction land can be designed on the basis of the control area and achieve by two aspects of total amount control and differentiated control.
