中文摘要：

通过选取15个副省级城市为研究对象，使用层次分析法和线性加权和法，测出1997—2003间各城市年度区域城市化综合水平。比较综合水平空间差异得出，东部发展持续领先于中西部城市，但中西部城市之间差异并不明显；由南至北的梯度差异格局显著，中部城市发展速度较快；城市群间差异较为突出。通过比较城市化子系统水平空间差异及其变化，发现城市化空间集聚水平与综合水平差异较为一致，经济增长质量、基础设施建设水平及生态环境建设水平的空间差异较为突出，但社会发展水平空间差异较小。我国区域发展总体格局、城市化历史基础、全球化的区域响应、制度创新的地区差异以及城乡与区域管理体制是空间差异形成变化的主要原因。

英文摘要：

The spatial units in this study are the 15 vice provincial cities. By AHP, the paper estimates the annual Regional Comprehensive Urbanization Level of every city in 1997- 2003. At first, through comparing the Spatial Disparties of Regional Comprehensive Urbanization Level, the paper reach some conclusion, the city of east China remains ahead of the city of west- central China, and the margin is extending continuonsly, but the margin between west China and central China is not obvious. The form of steps degree difference from south China to north China is obvious, and the city of central China develop quickly. The margin of Urban Agglomerations is obvious too, and it can be divided to two level of structure. Secondly, through comparing the Spatial Disparties of Urbanizational sub - system and it＇ s change, the paper has found that the martin of space concentration level of urbanization is similar to the margin of comprehensive level, and the space margin in economic progress, construction of infrastructural facilities, preserve of the ecologic and environment is obvious, but the space margin in social progress is minor. Thirdly, the spatial disparity and it＇ s change since 1997 is analyzed from three perspectives, namely overall regional space pattern of our country, urbanization foundation, region response to globlization, region diversity of system innovation and administrative system of urban and rural and region.
