城市化质量是经济城市化质量、社会城市化质量和空间城市化质量的有机统一,城市化发展质量的提升是加快推进我国城市化进程健康发展的关键。本文借助象限图法,通过对城市化质量、速度与城市化水平互动协调关系的分析,从经济、社会、空间三方面提出了由三类指标、12项具体指标组成的城市化发展质量综合测度的三维指标球及判别标准值,引进阿特金森模型,构建了城市化发展质量的分要素测度模型和分段测度模型,进而对中国城市化发展质量及其空间分异特征做了总体评价。研究表明,1980~2008年中国城市化发展质量总体处于中等水平,并正在缓慢提升,但提质速度慢于提速速度;分类城市化质量呈现出经济城市化质量〈社会城市化质量〈空间城市化质量的态势;全国分省城市化发展质量都在不同程度的提升,并呈现出“内陆→沿海→内陆→沿海→整体提高”的时空差异性,东部地区城市化质量总体高于中部地区,中部地区高于西部地区;城市化发展质量与城市规模不存在对应关系,并不是城市规模越大城市化质量越好,人口城市化水平并不能反映城市化发展质量的高低。
Urbanization development quality (UDQ) is the integrity of economic urbanization quality, social urbanization quality and spatial urbanization quality. The improvement of urbanization development quality is the key to expedite and facilitate the sound development of urbanization process in China. With the help of quadrant graph, through the analysis of the interactive coordination relation between urbanization quality, speed and urban- ization level, the paper proposes 3D index ball and discrimination standard value of comprehensive measures of urbanization development quality, which is composed of three categories of indexes and 12 detailed indexes. By introducing Atkinson model, the paper constructs the sub-element measure model and segmental measure model of urbanization development quality, and further makes an overall evaluation on the characteristic of China urbanization development quality and its spatial differentiation. Studies show that during 1980-2008, China's urbanization development quality reached a medium level generally, and was improving slowly. However, the speed of quality improvement is lower than that of speed improvement. The classified urbanization quality presents the stance of economic urbanization quality 〈 social urbanization quality〈 spatial urbanization quality; provincial urbanization development quality improves in varying degrees throughout China and exhibits the spatial and spatiotemporal difference of "inland→coastal area→inland→coastal area→improvement in general", thus urbanization quality in the east is higher than that in the middle, and that in the middle is higher than that in the west. There is no correspondent relation between urbanization development quality and city scale. It is not true that the bigger the city is, the better the urbanization quality is. The result shows that population urbanization level does not reflect the quality of urbanization development.
