中文摘要：

在构建市域经济系统与县域经济系统的耦合评价指标体系的基础上，采用灰色关联分析法，对2000--2010年间安徽省各市县域经济系统的时空交互关联进行分析．通过分析得出以下结论：市县域经济系统的关联变化表现明显的波动性与阶段性。大体可分为两个阶段：整体来看，安徽省市县经济的关联度水平呈现出外围高、内部低的圈层结构，其中，皖南高、皖北次之、皖中地区最低，且具有稳定的空间变化趋势：市县域经济系统内部要素间的交互耦合复杂．指标间的关联度属于中等及以上关联，基础设施建设水平是导致安徽省市县域经济系统耦合关联度值较低的原因。

英文摘要：

Based on the evaluation indicator system concerning the coupling between city-level economy and county economy, and using GRA （grey relationship analysis） method, this paper analyzes the interactive temporal--spatial correlation between city-level economy and county economy in the period of 2000-2010 in Anhui Province. The re- sults of the study show： （1） The changes of city-level and county-level economy system correlation present obvious volatile and periodic characteristics, and they are of two phases. （2） On the whole, the correlation degree presents a spatial change and an obvious circle structure in which the south of Anhui has higher correlation degree, the north of Anhui the lower, and the central Anhui the lowest. （3） The interactive coupling of the internal elements between two systems is complicated, the correlation of indicators is of medium or above-medium degree, and the level of infras- tructure construction is the reason for low coupling correlation degree between city-level economy and county-level economy. Therefore, to coordinate the development of city-level economy and county economy, measures should be taken to implement construction of infrastructures related to transportation, people＇ s life and production, etc.
