基于谱分析的物流发展周期

The Evolution Periods of Logistics Based on Spectral Analysis

进行物流发展的周期性研究,从微观角度定性解释物流周期性发展机理;选定谱分析为工具,对美国与中国的相关统计数据序列进行实证分析。研究发现:物流活动中的周期波动现象是较为普遍的;不同的物流指标数据序列隐含的周期有类似性;各种指标之间的联系具有普遍性,联系的密切程度因隐含周期长度的不同而不同;指标之间的波动在时间上表现出明显的差异。

The paper is about the evolution periods of logistics. A qualitative explanation on the evolution periods of logistics is put forward from a microcosmic angle. Spectral Analysis is selected to develop a demonstration analysis on statistical time series of logistics indexes in America and China. The following conclusions are reached： The periodic fluctuation is ubiquitous in logistics. The periods in different time series of logistics indexes are similar. The relations between different logistics indexes are ubiquitous and are impacted by different crytic periods. The periodic fluctuations of different logistics indexes are dissimilar.
