波罗的海干散货运价指数预测模型分析 总被引:2,自引:0,他引:2
2007年国。际干散货运输市场呈现出一片火爆的景象,波罗的海干散货运价指数比去年上升了1倍还多。海运市场如此火爆的原因是什么呢?本文首先从传统海运经济学角度,找出影响运价指数的可能因素,用计量经济学方法对影响因素进行分析。在发现上述影响因素无法通过检验之后,通过结合FFA市场,找出影响近年来海运运价的真正原因,并用EVIEWS软件进行拟合分析。参数估计具备较好回归拟合度和预测精度,能够很好地解释近年来海运市场异常的原因。 相似文献

受运输需求快速增长、长赐轮搁浅事件以及境外新冠疫情蔓延等因素影响,国际集装箱海运市场出现了前所未有的高运价局面,集装箱价格高达以前的几倍甚至十几倍,许多货主根本无力支撑如此高的运价,不得不放弃部分订单.在系统研究当前国际集装箱海运市场高运价形成原因的基础上,从公法和私法两个角度分别理性审视高运价的法律适用以及是否构成垄... 相似文献

我国远洋干散货船型经济论证 总被引:1,自引:0,他引:1
干散货运输市场是世界海运市场的3大市场之一,虽然运输市场机制趋于完善,但受运价、船价和油价的影响,市场波动较大。针对这一现实情况,文章以船型技术经济论证方法为基础,建立单船运输经济性测算模型,判定出最优船型,并对运价、船价和油价3个影响因子进行敏感性分析,为航运企业制定船队发展规划和港口企业制定到港船型规划提供参考。 相似文献

从去年开始到今年上半年,世界石油需求上升,油轮船队保有量出现下降,但是。运价却出人意料地仍维持在相当低的水平上。 1994.由于世界经济复苏,原油海运量增长了2.6%。另一方面,去年油轮拆解量达1600万载重吨,而新船交用量不到1000万载重吨,使世界油轮保有量降至3年前的水平。然而,油轮运价并无明显好转,特别是大型油轮运价。虽然去年下半年运价有所上升,但原因只是美国实行油轮油污责任证书(COFR)制度短时间内对市场造成影响,以及燃油价格大幅上涨,而不是因为油轮市场的供需平衡得以明显改善。 油轮运价低迷的主要原因,是原油海运结构的变化。据统计,1994年世界原油海运周转量仅增长0.5%,其中区域内短程原油 相似文献

In the short run, there can be substantial differences in spot freight earnings between geographical regions of the global freight market for bulk carriers. Such differences can be consistent with an efficient market if they are temporary and if they cannot be exploited financially by pursuing chartering strategies that are based on publicly available information. In this paper, we apply a simple optimal switching model to evaluate whether such chartering strategies exist. We model the spot freight rate differential between the Atlantic and Pacific basins as a mean-reverting Ornstein–Uhlenbeck process and the entry–exit decision using the discount factor approach, which results in optimal trigger values for the entry/exit from each basin. Our empirical results suggest that the market is spatially efficient during normal freight market conditions when there is a surplus of vessels. The tight market conditions during the 2003–2008 freight market boom caused a persistent upward bias in Atlantic freight rates, but also here we find little added value from pursuing an active switching strategy. 相似文献

Given that the freight rate is the price of a transportation service that cannot be traded or stored; the traditional form of the efficient market hypothesis (EMH) does not apply to the freight rate price process. However, the notion of market efficiency still applies in the freight market. In particular, under the hypothesis that the market is semi-strong-form efficient, it should not be possible to make excess profit by taking chartering positions in the freight market based on public information such as past levels of the spot freight rate or the shape of the term structure of freight rates. This paper contributes to the literature by proposing an alternative test of market efficiency in the bulk freight market. We utilize technical analysis based on the history of spot freight rates and investigate the profitability of such chartering strategies for a tanker operator. The chartering decisions are based on identification of the peaks and troughs in the freight market cycles using kernel smoothing of the spot freight rate history. The empirical results suggest that a large tanker operator (e.g. a pool) could have achieved significant profits without investing in ships by trading on such information, although this does not hold in the most recent subset of the sample. 相似文献

通过中日航线的集装箱运价指数与中韩航线对比,反映中日航线实际运价状况,以市场集中度测算反映市场结构特点。中日航线的市场结构呈现低集中度特点,这决定了在市场竞争程度较高,在服务产品同质性较高的条件下,价格成为主要的竞争手段,中日航线运价水平整体上处于正常状态。政府主管机关对运价的监管涉及运价水平、稳定性、运价的合理构成以及暗中回扣等问题,运价的合理构成和暗中回扣应是重点规范的领域,有必要考虑运价报备制度的价值。 相似文献

通过对试行的运价报备制度的作用与实质的分析提出了在目前国际集装箱运输市场以运价报备制度作为运价管理模式是合适的。运价报备制度比传统的各种运价管理模式刚性小、易于被业界各方接受,又可以作为国家宏观管理的一种政策手段,为长期稳定集装箱运价起到积极的作用,在目前运价全面放开的市场背景下还可以作为一种新运价管理模式。 相似文献

The main result of this article is that freight rates and second hand prices in the dry bulk market seem to be stationary. By unit-root tests, an established tool for testing for random walk in economic time series, the random walk hypothesis can be rejected in most cases for the freight rate samples. This result is in contrast to the findings of a number of papers during the 1990s. However, the results confirm classical shipping market models that indicate stationarity in freight rates, which is not the case if the freight rates follow a random walk. By transforming all observations from US$ to Japanese yen detrended freight rates and prices seem to become stationary and volatility is reduced. 相似文献

This paper tests two fundamental hypotheses concerning international maritime statistics. The first one deals with the question of stationary of the maritime market statistics. The second hypothesis tested is the assumption that the international maritime statistical time series are not distributed according to a normal of Guassian probability law, but rather belong to the same family of distributions with distinctly different critical parameters. Through well documented statistical methods, the paper concludes that the international freight rates observed on a day to day basis are generated by a random walk process. The paper finds that the shipping industry's conventioal wisdom is essentially correct. 'Last done' is as good a forecast of tomorrow's freight rate as any other generated by more sophisticated forecasting methods. Furthermore, freight rates and secondhand tonnage prices fluctuate closely together. The freight rates are generated by stochastic processes fully described by the Paretian family of distributions. The critical parameters of these distribution, the characteristic exponents, are such that the risk conscious ship operator can indeed reduce his exposure to risk by securing a correct set of freight rate contracts. 相似文献
