中文摘要：

区域间经济影响的反馈效应是多区域经济研究的重要议题之一，对闭合反馈回路的研究则涉及到区域间相互关联的层级问题。本研究以中国首张8个区域的区域间投入产出表为基础，从区域间的反馈回路与层级分析角度对中国经济的空间结构进行初步探讨。研究发现．中国目前仍以区域内产业间的关联为基本特征，区域间联系仍较弱。从区域间相互影响的反馈效应看，存在着三个属于较高层级的大的闭合性反馈回路，它们占中国中间贸易流量的64.3％.而四个较低层级的反馈回路只占中间贸易流量的35．7％，而且它们都存在着两个更小的闭合性反馈回路。

英文摘要：

Research on the feedback effects is one of the important issues of the inter-regional economies＇ interaction and the feedback loop and interregional hierarchies are always explored simultaneously when we deal with the feedback effects. Based on the first multiregional Input-Output Table for China 2000, this paper explores the feedback loops and interregional hierarchies of Chinese spatial economic structure, finding that the intra-regional linkages are the fundamental characteristics of Chinese spatial economic structure and there still exist small linkages among different regions. This paper reveals that the top three complete feedback loops, which belong to the higher hierarchies, account for 64.3 percent of the total intermediate transaction, and the remained four feedback loops, which belong to the lower hierarchies, account only for 35.7 percent and can each be decomposed into two closed sub-loops.
