This study focuses on the expected impact of Northern Sea Route (NSR) usage and the Panama Canal (PC) expansion on liquefied natural gas (LNG) imports of Asian countries, from not only the macroeconomic viewpoint but also diversification of the supplying countries. First, the amounts saved from shipping costs due to these events are estimated, based on scenarios on the navigable period of the NSR, transit fee of the NSR considering the exchange rate between the Russian ruble and US dollar, and bunker fuel price. Second, a spatial general equilibrium model based on macroeconomic theory is applied to predict changes in LNG trade patterns and measure economic impacts due to the reduction of shipping costs. Finally, the impacts of NSR usage as well as the PC expansion on LNG imports of Asian countries are discussed based on the calculations. The results show that diversification of supplying countries for LNG imports can be observed, especially in Japan, the largest LNG importer in the world, and other Asian countries are secondarily affected by changes in Japan’s import pattern, with limited impacts on these countries’ national economies.  相似文献

As market price, shipping freight rates should in theory be stationary, but most empirical tests have found them to be non-stationary. To examine the causes of this theoretical–empirical inconsistency, we investigate the sensitivities of the stationarity of shipping freight rates from two perspectives: sample length and sample window. Longer samples are found not sufficient to make them stationary. Instead, sample windows separated by structural breaks are tested as stationary. Moreover, freight rates are found to have entered into a new phase since the 2008 financial crisis. This study contributes to the literature on the stationarity of shipping freight rates by providing an explanation for the theoretical–empirical inconsistency.  相似文献

The paper investigates collaborative and semantic patterns that emerged between 1967 and 2013 about the theme of container shipping based on a corpus of 294 articles published in scholarly journals within the fields of transportation, supply chain, economics, geography, regional planning and development, and operations research. An analysis based on the co-occurrence of title words allows identifying dominant sub-themes and their evolution. Main results point to the gradual diversification of container shipping research, from the dominance of economics towards a more trans-disciplinary set of approaches which integrate port-related activities and multimodal networks. Yet, disciplinary specialization remains strong up to nowadays so that container shipping research remains rather fragmented. While co-authorships have increased over time, they remain polarized by few, weakly connected research battalions. Our study suggests that research on container shipping would benefit from more frequent contacts between such communities to foster in-depth cross-disciplinary studies and fundamental cooperation.  相似文献

The continuous ice retreat in the Arctic has fueled speculations of new transarctic shipping routes to be operational soon. While the media vigorously propagates the great potentials of these routes, researchers have accessed the feasibility of opening of transarctic shipping routes from various perspectives; diverse and some polarized conclusions have emerged. This paper aims to critically review the studies that examine the necessary conditions and requirements that make transarctic shipping routes sufficiently viable. We mainly focus on two aspects: navigation conditions and commercial features. Selected studies are analyzed and compared in depth. Finally, possible future research directions are put forward.This article is a revised and expanded version of a paper entitled Viability of Transarctic Shipping Routes: An Overview, presented at the International Conference on ‘Global Integration of Economies and Connectivity Development’ in Taiwan on 31 August 2015.  相似文献
