文章摘要:识别我国城镇化发展的时空差异和演变特征对于认清我国城镇化发展的潜在规律,提升区域整体竞争力具有重要参考意义。本文利用多尺度分析的方法,从全国、各经济带、各省三个尺度对城镇化发展的不均衡特征进行了全面分析。并以奥运年2008年为例,对于影响各省城镇化发展不均衡性的因素进行了探测分析。结果表明:①我国城镇化发展不均衡性的总体水平在逐年减弱,从空间看,表现出沿海各省城镇化发展的不均衡性整体小于内陆,西部地区各省则呈现逐年扩大趋势。其中,甘肃省和... 展开

文章摘要:识别我国城镇化发展的时空差异和演变特征对于认清我国城镇化发展的潜在规律,提升区域整体竞争力具有重要参考意义。本文利用多尺度分析的方法,从全国、各经济带、各省三个尺度对城镇化发展的不均衡特征进行了全面分析。并以奥运年2008年为例,对于影响各省城镇化发展不均衡性的因素进行了探测分析。结果表明:①我国城镇化发展不均衡性的总体水平在逐年减弱,从空间看,表现出沿海各省城镇化发展的不均衡性整体小于内陆,西部地区各省则呈现逐年扩大趋势。其中,甘肃省和安徽省表现出明显的空间异质性特征。这主要是由于两省的城镇化整体水平滞后,城镇结构体系不完善。②各省区城镇化发展不均衡性的成因分析表明,人口规模、城市体系结构特征、人口结构特征以及城乡差异水平成为影响不均衡性的主要原因。这一结果为各地城镇化方案的制订提供了基本支撑。

Abstract:This paper aims to recognize characteristics of urbanization in China both spatially and timely. Characteristics of inequality were detected in our paper from three scales:whole country,three economic belts,and provincial scales. Gini coefficients of urbanization in the mentioned three scales were calculated to measure inequality of urbanization development in China.It was found that with the increase of urbanization these years in China, inequality of country-wide decreases year by year. However,inequality of three economic belts varies spatially. The inequality in the east part of China,whose development is relatively higher than others,was the lowest in the three parts. And the inequality of urbanization in the west part was the highest,while its economic development is lowest in three parts.When it turns to the provincial scale,the characteristics of inequality of urbanization seem much similar with three economic belts,that gradient change from east to west. However,An Hui and Gan Su provinces seem great difference with provinces in surrounding.Furthermore,in our paper, regression model was built to analyze implications of inequality of urbanization in provincial scale. And we found that population scale,structure of urban system,potential of labor,and variance between rural and urban were all crucial factors to inequality of urbanization. To be mentioned,the ratios of amounts of medium-sized cities in one province was especially significant in our model,which tell us that development of medium-sized cities may help reduce inequality of regional development.
