摘要:

国际干散货海运市场源于国际经济贸易衍生需求,受世界经济贸易外部环境影响,是一个典型的周期性市场.海岬型干散货市场作为国际海运市场重要组成部分,研究其周期特征具有重要意义.运用傅里叶变换和谱分析理论,在检验序列平稳性基础上,建立海岬型海运市场周期特征谱分析模型,对其周期性波动进行理论研究和实证分析.海运市场周期性谱分析方法能够衡量市场指标时间序列中各周期因素相对重要程度,确定周期长度.分析时间序列周期特征,特别是确定不同频率的周期成分对序列变化影响时,谱分析是非常有效的数学工具.研究结果表明,海岬型干散货海运市场具有明显周期性特征,最显著的周期是1~1.5 年时间,其次是5 年左右的短周期,这种周期性规律可为海运企业船舶投资和市场经营提供决策依据.

Abstract:

International dry bulk shipping market demand is the international economy and trade derivative, a typical cyclical market affected by the impact of eternal environment of world economy and trade. Capesize dry bulk cargo shipping market is the leading part of dry bulk shipping markets, so study on its market cycle is of great importance. Referencing to Fourier transform and spectral analysis theory based on the stability of the sequence test, the paper model the spectrum analysis of shipping market of Capsize dry bulk to deal with the periodicity of it empirically and theoretically. The spectral analysis of shipping market of Capesize dry bulk cycle fluctuation can compare with the importance of different wave length fluctuation and calculate the wave length of the its cycle fluctuation. In the analysis of implicit cycle characteristics of time series, especially when determining the impact of different frequency cycle components to the sequence variation, spectral analysis is a very effective mathematical analysis tools. The results show that the Capesize dry bulk shipping market has obvious periodicity. The most significant period sequence is one year to one and a half year, and the short period is about 5 years. The periodic feature can provide decision-making basis for the vessel investment and market operation of shipping enterprises.

Key words: waterway transportation, cyclical fluctuation, spectral analysis, Capsize dry bulk ship, shipping market
