城市空间增长效应评价方法——以重庆市为例

在城市空间快速增长背景下,开展城市空间增长效应评价研究,有助于解决城市空间增长中出现的问题,可为确定城市空间发展战略、制定空间发展政策提供依据。城市空间增长效应评价方法旨在定量、客观地判断城市空间增长过程中要素配置与运行是否合理、高效和公平。笔者建立了结构配置效应、经济配置效应和公平配置效应3个方面的评价体系,通过目标法对城市空间增长效应进行评价,得出空间增长效应评价函数。以重庆市为例进行实证分析,结果显示:重庆市2004—2013年间的城市空间增长效应总体呈上升发展趋势,结构性、公平性趋好;合理配置效应和经济配置效应波动显著,反映出城市建设面临的用地结构优化、用地效率提升等方面的问题。

Evaluation method of urban spatial growth effect: Taking Chongqing city as an example

In the background of the rapid growth of urban space,it is helpful to carry out the study of urban spatial growth performance to solve the problem of urban spatial growth.This study provided basis of determining the development strategy of urban space and formulating spatial policy. Evaluation methodology of urban spatial growth effect is the way to j udging the element configuration and the operation of elements is reasonable,efficient and fair during the process of urban growth space.Three evaluation systems are established in this paper,there are structure effect,economic effect and fair allocation effect.Evaluation of urban spatial growth effects by objective law will get space growth effect evaluation function.An empirical analysis of Chongqing city as an example we can get these results:the urban spatial growth effect of Chongqing from 2004 to 2013 is on the rise,structure and fairness is also on the rise;the reasonable allocation effect and the economic allocation effect are significant.These results reflect the urban construction land use structure optimization,land use efficiency and other aspects of the problem.
