中文摘要：

文章以非均质空间结构的层次关系为虚拟轴,以区域差距的三种基本形态为纵轴,以竞争与互补的互动关系为横轴,力图构建以区域差距为主的结构分析和以空间互动为主的关系分析相统一的理论分析框架,运用变异系数变形及考虑空间横向和纵向联系的Dendrinos-Sonis模型相结合的方法,对1978-2008年我国八大区域差距与空间互动的关系进行了实证分析,结论是：（1）我国八大经济区域中的经济差距包括良性、中性与恶性三种基本类型;（2）非均质空间特征下,我国仍以计划空间为主导,根据纵向联系作用于横向联系带来的互动方式不同,多层次空间互动模式存在差异;（3）恶性区域差距向良性区域差距的协调发展需要形成互补与竞争的适配性。

英文摘要：

This paper regards the layer relationship of heterogeneous spatial structure,three basic forms of regional disparity,and the interaction between competition relationship and complementary relationship as virtualaxis,vertical axis and horizontal axis respectively,and tries to construct a theoretical analytical framework which integrates structure analysis based on regional disparity and relationship analysis based on spatial interaction.Then it employs the deformation of coefficient of variation and Dendrinos-Sonis model taking spatial horizontal and vertical connections into account to make an empirical analysis of the relationship between regional disparity and spatial interaction in 8 economic regions of China from 1978 to 2008.It arrives at conclusions as follows： firstly,the economic disparity in 8 economic regions can be classified into three forms,namely benign,neutral and malignant;secondly,under heterogeneous space,China is oriented by planned space and the multi-layer spatial interaction models differ according to different interaction forms caused by the effect of vertical connection on horizontal connection;thirdly,the coordinated development from malignant regional disparity to benign regional disparity requires the formation of the suitability between complementary relationship and competition relationship.
