摘　　要：改革开放以来我国二元对比系数仍很低,1984年达到最高值0.264,2005年也仅有0.178,发展过程很不稳定,经历了增大—减小—增大—减小,2004年以来又有增大的趋势。从地带间的二元对比系数平均值可知,西部二元对比系数最低,中部二元对比系数先高于东部,后又低于东部,2005年中部的二元对比系数重新高于东部,三大地带间的极差和极值比经历了减小—增大—减小—增大,总体而言地带间的差距具有减小的趋势。省城间的区位熵表明:东、中、西部省城的二元对比系数都有高有低,虽然高区位熵的省城主要分布在东、中部,但无论是发达的东部省城还是落后的西部省城都存在低区位熵。最后运用相关性分析和回归分析剖析了影响二元对比系数提高的主要因素。Dual contrast coefficient is also very low since the reforment in china,the highest is 0.264 in 1984,but in 2005,it is only0.178.The development course of Dual contrast coefficient is not stable,which can be described as increase-decrease- increase-decrease,since the 2004,it is increasing too.The average of dual contrast coefficient among three regions indicates that the lowest is west region,at first the middle region is higher than east region,then it lower than east region from 1990,but it also higher than east region in 2005.The changeable course is decrease-increase-decrease-increase in the dispersion of extremum and the proportion of extremum.On the whole,the dual contrast coefficient among the tree regions are decreasing.Location quotient indicates that the three regions are all exist the high or low dual contrast coefficient,though most of the high Location quotient are lie in west.The research of correlation and regressive analysis reveals that the main influence factors of dual contrast coefficient are the development of industrialization level,primary industry leveksecondary industry level.
