摘要:

利用DEA模型测算了2001~2012年长三角、京津冀及珠三角三大城市群土地利用效率,通过研究得出以下结论: 长三角、京津冀和珠三角三大城市群的城市土地利用效率总体上均呈现下降的趋势,下降比例分别为6.06%、2.86%、24.34%,特别是珠三角城市群下降幅度最大,为长三角和京津冀的4倍和8.5倍,证实珠三角城市群城市土地利用效率下降的迅速性。 京津冀城市群城市土地利用效率整体偏高,冗余量相对较少,降速明显低于长三角和珠三角两大城市群的城市土地利用效率。长三角、珠三角城市群的土地利用效率处于持续降低的状态。 三大城市群城市土地利用效率的规模报酬有效性的城市比例下降幅度分别为10.53%、10%、33.34%,珠三角下降幅度最大,为长三角和京津冀的3.17倍和3.33倍; 长三角城市群土地利用效率差异较大,京津冀城市群、珠三角城市群“中心-外围”现象明显。

Abstract:

This article uses DEA model to calculate the land use efficiency of urban agglomerations in the Changjiang River Delta, Beijing-Tianjin-Hebei and the Zhujiang River Delta. The results show: 1) The land use efficiency of urban agglomerations showed a downward trend in 2001-2012, decline rates being 6.06%, 2.86%, 24.34% in the Changjiang River Delta, Beijing-Tianjin-Hebei and the Zhujiang River Delta, respectively, and that of the Zhujiang River Delta urban agglomeration was the largest; 2) The overall efficiency of urban land use of Beijing-Tianjin-Hebei was high and had a relatively small amount of redundancy, deceleration of that was significantly lower than those of the two deltas. The latter two continued to be in the reduce state; 3) The validity of returns to scale of land use efficiency showed a downward trend, decline rates being 10.53%, 10% and 33.34% in the urban agglomerations of the Changjiang River Delta, Beijing-Tianjin-Hebei and the Zhujiang River Delta. 4) The "Center-Periphery" phenomenon was evident in the three urban agglomerations.

Key words: DEA model, three urban agglomerations, land use efficiency
