国际货物运输中的隐名代理问题

随着我国对外贸易事业的深入开展,国际贸易中的隐名代理问题亟须规范化。起源于英国的隐名代理制度,在英美法系由来已久日趋完善。世界上大多数国家都参照英国的隐名代理制度,制定了有关隐名代理的法律规范。我国目前虽然规定了一些有关隐名代理问题的实务操作办法,但缺少对隐名代理相关法律问题的明确规范,建议通过立法的形式对隐名代理制度予以完善。

Comparing carbon dioxide emissions of trucking and intermodal container transport in Taiwan

This paper examines carbon dioxide emissions of truck-only transportation using activity-based emission modelling and compares those with intermodal coastal shipping and truck movements. The results reveal that replacing long-haul truck transport with the intermodal can significantly reduce carbon dioxide emission significantly because of the efficiency of maritime fuel.     

The effectiveness and costs of speed reductions on emissions from international shipping

Greenhouse gas emissions from international shipping are an increasing concern. The paper evaluates whether vessel speed reduction can be a potentially cost-effective CO₂ mitigation option for ships calling on US ports. By applying a profit-maximizing equation to estimate route-specific, economically-efficient speeds, we explore policy impacts of a fuel tax and a speed reduction mandate on CO₂ emissions. The profit-maximizing function incorporates opportunity costs associated with speed reduction that go unobserved in more traditional marginal abatement cost analyses. We find that a fuel tax of about $150/ton fuel will lead to average speed-related CO₂ reductions of about 20–30%. Moreover, a speed reduction mandate targeted to achieve 20% CO₂ reduction in the container fleet costs between $30 and $200 per ton CO₂ abated, depending on how the fleet responds to a speed reduction mandate.     

Seasonality patterns in the container shipping freight rate market

Shipping indexes have attracted many researchers because they reflect the overall trend of corresponding seaborne markets and can provide implications for the future. Apart from the Baltic Dry Bulk Index (BDI) and correlated indices, the China Containerized Freight Index (CCFI) has been gaining more attention. As a country with large-scale manufacturing, China is an important exporting country and the CCFI was chosen to reflect the container shipping market because the data are more convincing and representative. There have been no systematic attempts to understand the seasonality patterns of container freights. Seasonality patterns reveal the regular fluctuation patterns within a 1-year period. They exist in time series, which are observed more than once a year, like the CCFI. To investigate the nature of seasonality (stochastic and/or deterministic) in container freight rates across different line services, we analyze the CCFI. This paper uses the HEGY method and Monte Carlo method comprehensively to figure out the small sample problem. In addition, seasonal dummy variables are used to test deterministic seasonality. Except for the Japan service series, which contains a half-year unit root, the other container freight rates seem to only involve a non-seasonal unit root at the zero frequency. Deterministic seasonality exists in all the line service series. Furthermore, the seasonality depends on the balance between supply and demand. Under this premise, the seasonal law of freight rates is much obvious.     

Governance of Shipping Emission of SOx in China's Coastal Waters: The SECA Policy,Challenges, and Directions

Emission governance of air pollutants from ships is a common challenge for the world's shipping industry. Under the framework of the International Maritime Organization (IMO), Europe, North America, and other developed regions and countries have established strict ship Emission Control Areas (ECAs). With some of the largest ports in the world, China suffers severe air pollution from ships, posing a threat to the air quality and public health of the coastal cities. To strengthen the control and supervision over air pollutants, such as ship-emitted sulfur oxides (SO_x) in coastal areas, China issued a Sulfur Emission Control Area (SECA) policy for ships in January 2016. However, the new SECA policy lags far behind IMO's existing ECA policies, and continues to face many challenges during implementation. This paper outlines the main framework of China's ship SECA policy, analyzes the legal governance basis, discusses major potential challenges for implementing the policy, and puts forward suggestions for future governance. This research aims to promote the effectiveness of China's sulfur emission-reducing SECA policy by putting forth novel ideas for policymakers and stakeholders.     

Evolution of green shipping research: themes and methods

Over the past 30 years, there have been growing concerns on the environmental impacts of maritime transportation, which have attracted great attention from both academia and practitioners. Understanding developments in this area can help guide future research. We conducted a comprehensive review of green shipping research, comprising 213 papers published in transportation journals in SSCI of 2017 over the period 1988–2017. We find that research on green shipping has increased greatly since 2012, accounting for 77.5% of the reviewed papers. The main focus today on green shipping was on air pollution, and the classification of green shipping practice, such as technical measures, operational options, market-based measures, and recycling and reusing, is becoming clear. According to the existing studies, future research on green shipping must strengthen technology research to not only solve practical problems, but also to establish a theoretical green shipping system. Moreover, researchers from different countries could cooperate with each other to give effective suggestions on setting standards and laws of green shipping. Finally, we identify the future research themes will focus on setting up green shipping system and legislation and policy.     

Risk influencing factors analysis of Arctic maritime transportation systems: a Chinese perspective

Recently, the melting of Arctic sea ice and development of maritime technology are enabling the regular voyages in Arctic waters. However, the Arctic maritime transportation system (AMTS) is a complex and dynamic system with respect to human, technical, environmental and organizational issues. For example, ships operating in Arctic waters suffer severe weather conditions, fully and partially ice-covered waters, and are also difficult to search and rescue in ice-covered Arctic waters due to remoteness from lands. These risk factors will influence the safety and security of ships operating in Arctic waters. For this, this paper identifies potential risk influencing factors (RIFs) for the AMTS from human, technical (ship), environmental and organizational aspects. An analytical hierarchy process (AHP) method is used to analyze the hierarchical relationships and calculate the relative importance of the selected RIFs. Due to the complexity and uncertainty involved in the comprehensive analysis of RIFs for the AMTS, fuzzy sets are incorporated into AHP analysis to represent and treat the epistemic uncertainty. The identified critical RIFs in this study can be used to propose specific guidance for the operations of crews on board, ship owners, and ship managers.
