中文摘要：

本文从三个方面构建了城乡协调发展度指数,对中国2000—2008年31个省城乡协调发展程度的整体变化及在大区上的空间差异进行了评价和原因探讨。结果显示,中国城乡协调发展程度整体呈现上升趋势,主要原因是城乡增长率差异系数的降低,说明我国近些年的支农惠农和统筹城乡发展的政策效果显著。东部和西部地区城乡发展逐步协调,而中部和东北地区城乡发展协调度下降。东部城市和农村基本实现共同富裕,而西部是较低水平上的协调。东北地区先大幅下降后缓慢上升,中部地区的城乡协调发展度目前是最低的,变化较为复杂。

英文摘要：

On the basis of the connotation analysis of the coordinate development,constructing the index of the coordinate development from three aspects of the divergence between rural and urban areas,select the 2000 to 2008 period,this paper not only discusses the varied degree of the coordinated development between urban and rural areas of 31 provincial unit in China,but examines the evolution pattern and its mechanism of the level of coordinated economic development between urban and rural areas in the four sub-region（that is： the eastern region,the western region,the Northeast region and the central region） in China as well.It presents that,from 2000 to 2008,the level of the coordinated development of urban and rural areas of China is overall upward,the index value of coordinated development of urban and rural is increased from 0.00627 in 2000 to 0.99 in 2008.It is shown that,in recent years,the policy effects of China＇s support and benefit agriculture is remarkable.For the four sub-regions,in general,the eastern and western regions are gradually coordinated between urban and rural development,while urban and rural development in central and northeastern regions decreased coordination.In the eastern region,urban and rural areas basically realize common prosperity and step into the advanced stage of development： the integration of urban and rural areas and the western area is lower level of coordination.The northeast area,in 2002 as the inflection point,decreased significantly after the first rise slowly,reflects the revitalization of northeast old industrial base strategy and the abolition of agricultural tariffs policy implementation effects began to show.Traditional grain producing areas of urban and rural dual structure of the economy are still outstanding,rural issues are still very serious.By calculating the changes of difference between urban and rural residents＇ income,the spatial pattern evolution of the overall coordinated development between urban and rural areas in Chinese province level can be f
