摘要
基于2006~2016年中原城市群各地市面板数据,运用超效率SBM模型和Malmquist模型测算城市土地利用效率并分析其时空差异,基于此借助空间计量模型分析中原城市群城市土地利用效率的影响因素,旨在促进土地要素的合理配置和区域协调发展。研究结果表明:(1)2006~2016年中原城市群城市土地利用效率整体水平不高,呈现先下降后上升波动变化趋势。高效率聚集区主要分布于中原城市群的西部,而东部的高效率聚集区逐渐向北部迁移。(2)城市土地利用过程中要素投入以及非期望产出的冗余是造成中原城市群土地利用效率损失的主要原因之一。(3)中原城市群城市土地利用效率存在正向的空间自相关。(4)经济发展水平、产业结构对于提高城市土地利用效率具有显著的促进作用,而财政压力、城市房地产投资对提升城市土地利用效率具有显著的抑制作用。(5)研究区域的城市土地利用效率存在空间溢出效应。因此要提高城市土地利用效率,中原城市群需要进一步加强城市之间的联系,建立联动发展机制,增强城市土地利用的系统性和整体性。
Based on the panel data of 29 cities in the Central Plains Urban Agglomeration from 2006 to 2016, this paper evaluated the urban land use efficiency and analyzed its spatial-temporal differences by the super-efficient SBM model and the Malmquist model, and then used spatial econometric model to analyze the influencing factors of urban land use efficiency in the Central Plains Urban Agglomeration. The aim was to promote the rational allocation of land and coordinated regional development. The results showed that:(1) From 2006 to 2016, the overall level of urban land use efficiency in the Central Plains Urban Agglomeration was not high, showing a trend of declining first and rising later. The high-efficiency clusters were mainly distributed in the west of the Central Plains Urban Agglomeration, while the high-efficiency clusters in the east gradually migrated to the north.(2) The redundancy of input and undesired output in the process of urban land use was one of the main reasons for the loss of land use efficiency of the Central Plains Urban Agglomeration.(3)The urban land use efficiency of the Central Plains Urban Agglomeration had positive spatial autocorrelation.(4) The level of economic development and industrial structure had a significant role in promoting urban land use efficiency, while fiscal pressure and the urban real estate investment had an obvious inhibitory effect on improving urban land use efficiency.(5)The urban land use efficiency of the study area presented an obvious spatial spillover effect. Therefore, to improve the efficiency of urban land use, the Central Plains Urban Agglomeration should strengthen further the connection between cities, establish the linkage development mechanism, and enhance systematization and integrality of urban land use.
