Grey Associative Analysis of Regional Urban-Rural Coupling in China
基于灰色系统理论构建城乡文化耦合系统的评价指标和关联模型，分析了中国31个省份的耦合度、机制及空间分布，发现中部高于东西部、南方高于北方，并将省份分为和谐、改善、冲突和相互依赖四种类型。
In this paper,the evaluation index system and associative model between urban-rural cultural coupling system based on the theory of grey system,and the coupling degree,the mechanism as well as spatial distribution have been discussed.The results show that:(1)There is a rather close relationship between the systems.The absolute gap is greater than relative one.(2)The interaction between factors is the main driving power of the coupling system.(3)Such problem domains as Clash、Alternative and Alienation still exist between reality systems.(4)The spatial distribution of coupling degree shows that central China is higher than those of eastern coastal and western area,and the south is higher than the north.Natural environment,economic structure,history and institutional factors are the main reasons leading to the spatial difference.(5)According to the coupling degree and economic development,the 31 provinces can be divided into four types as harmony,amelioration,confliction and interdependence.The majority type is confliction,followed by interdependence.
