Feedback loops analysis of Japanese interregional trade, 1980-85-90
分析1980-85-90年日本区域内和区域间贸易流的层级结构，利用叠加原理提取反馈循环，揭示水平与垂直贸易分工的经济现象，并通过可视化呈现结果。
This paper examines the hierarchy of intra‐ and inter‐regional trade flows within the Japanese economy over the period 1980–85–90. The methodology provides an opportunity to explore links between feedback loops analysis and the extraction of a hierarchy of flows using ideas from superposition principles. The resulting analysis of trade feedbacks may be seen to reflect the economic phenomena of horizontal and vertical trade specifications. While the process is explored analytically, the results are presented using visualization to help identity the different permutation matrices presenting the hierarchy of trade feedback loops.
