昆明市城镇化对土地利用效率影响的实证分析

分析昆明市城镇化对土地利用效率影响程度，为昆明市城镇化发展提供一种视角和实践依据。运用SPSS主成分分析及格兰杰检验对昆明市土地利用效率的城城镇化影响进行综合评价。结果表明：（1）近年来昆明市城镇化进入稳健发展期，但土地开发利用欠佳；（2）协整检验结果显示，在长期内一个变量的变动可引起另一个变量的改变，即城镇化综合水平和土地利用综合指数之间存在长期稳定的均衡关系；（3）城镇化的有序进程与土地利用状况变动在短期内不存在因果关系。长期来看，城镇化综合水平有利于土地的集约利用的改进；但短期内，城镇化综合水平不利于土地集约利用，二者还未形成一个稳定的相互关系。

The Positive Analysis of the Effect of Urbanization on Land Utilization Efficiency in Kunming

The study aims to know the urbanization impact on land use and get a new perspective and theoretical basis for the development of urbanization in Kunming. The SPSS and Grainger test were used for evaluation. The results showed that: firstly, in recent years the development of Kunming entering a stable period, but land development is poor; secondly, the results of Cointegration test showed that variable changes could be caused by another variable change in long term, it meant that there was a long-term stable equilibrium relationship between the urbanization and the land utilization; thirdly, there was no causal relationship between urbanization development and land use in the short term. The level of urbanization was conducive to intensive use of land in long term, but the comprehensive urbanization level was not conducive to intensive use of land in the short term, and a stable relationship had not been formed.
