Orchestrating transnational environmental governance in maritime shipping     

《Global Environmental Change》2015

Maritime shipping is the transmission belt of the global economy. It is also a major contributor to global environmental change through its under-regulated air, water and land impacts. It is puzzling that shipping is a lagging sector as it has a well-established global regulatory body—the International Maritime Organization. Drawing on original empirical evidence and archival data, we introduce a four-factor framework to investigate two main questions: why is shipping lagging in its environmental governance; and what is the potential for the International Maritime Organization to orchestrate emerging private ‘green shipping’ initiatives to achieve better ecological outcomes? Contributing to transnational governance theory, we find that conditions stalling regulatory progress include low environmental issue visibility, poor interest alignment, a broadening scope of environmental issues, and growing regulatory fragmentation and uncertainty. The paper concludes with pragmatic recommendations for the International Maritime Organization to acknowledge the regulatory difficulties and seize the opportunity to orchestrate environmental progress.  相似文献

王伟  金凤君 《地理研究》2020,39(5):1088-1103

采用船期表数据,以全球前20位航运企业中的18家为研究对象,剖析各企业航线网络的异同点,并探讨企业航线配置的影响因素。研究表明：各企业航线网络均具有小世界和无标度特征,东亚是航班的首要集聚区,并且均为轴辐连接与点对点连接并存的混合式网络;各企业航线网络的市场广度和深度各异,根据航班的空间分布特征可将企业划分为4种类型,其中高丽海运、汉堡南美、阿拉伯轮船和万海航运专注于特定区域的细分市场,且拥有不同于全球枢纽港的企业枢纽港;港口腹地货源、港口自然条件及作业效率、海运保护政策、企业自身能力等是影响企业航线布局的重要因素。本研究有助于揭示航运企业的航线组织模式,为港口管理者决策提供参考。  相似文献

北极航线战略利益争夺的博弈态势与中国对策     

章成  杨嘉琪 《世界地理研究》2022,31(5):919-928

北极航线包括东北航线、西北航线与北冰洋中央的穿极航线。作为联结亚欧最短的航运线路,北极航线独有的战略地位与潜在开发价值已吸引北极域内外国家的关注并对北极区域作出战略倾斜,北极航线由此成为各国战略利益争夺的前线阵地。虽然北极航线由于其自身地缘特征实际为北极航线沿线国家所掌控,但航线自身的公共属性决定了其战略价值的“外溢”,北极域外国家在北极航线同样具有重要的国家利益。北极航线目前存在国际规则不成体系、国内法与国际规则相冲突等矛盾,俄罗斯与加拿大将东北航线与西北航线“内水化”是造成国内外规则冲突的根本因素。中国作为北半球航运大国,北极航线的开通将进一步推动我国进出口贸易以及保障我国石油能源安全储备,对我国具有重大战略意义。由此,提升北极航运的参与度,以“负责任大国”形象与北极国家合作的方式参与北极事务以维护本国航运利益,进而推动北极航运治理规则体系的完善,是适合现实参与北极航线实践的中国对策。  相似文献   

Service contracts—An instrument of international logistics supply chain: Under United States and European Union regulatory frameworks     

Peter Marlow  Rawindaran Nair 《Marine Policy》2008

Service contracts have emerged as an important instrument to secure a long-term relationship between carriers in the container shipping industry and shippers requiring scheduled services covering a global market. This contract, entered into largely on an individual and confidential basis, continues to enjoy anti-trust immunity under current United States and European Union regulations. It will continue to be in place even after the EC Council Regulation 4056/86 is repealed in October 2008 although it may operate in a modified way because of the absence of the common external conference tariff. This article examines the implications of this instrument on the international supply chain and explores its future role in defining efficiencies in international trade flows.  相似文献   

我国极地航运能力建设和高冰级船队发展对策分析          下载免费PDF全文

寿建敏 《极地研究》2018,30(4):419-428

我国在南极和北极的活动日益增多,参与南北极事务和争取极地资源的利用已经成为国家未来向外扩展的重要举措之一。随着气候变暖,极地冰融速度加快,尤其是北极航运窗口期越来越长,两极资源利用和科考活动的需求量越来越大。而目前我国用于航行两极,尤其是北极的高冰级商业化船队十分缺乏,航运的陆基支持保障能力缺少,这将严重影响我国极地事业和商业航运运营的发展。本文通过对不同冰级船舶的保有量、建造技术能力、船舶运营和极地港口设施等各环节的分析,得出我国缺乏带较高等级冰级符号且可抗浮冰厚度1m及以上的极地航行船舶、相应极地航运能力不足的结论,并提出了我国建设极地航运能力的对策建议,为我国建设一支能在极地航行且带较高等级冰级符号船舶的船队、破冰船队以及建设极地陆基航运支持保障能力等提供决策参考。  相似文献   

The identification of global strategic shipping pivots and their spatial patterns     

Chengjin Wang  Peiran Chen  Yunhao Chen 《地理学报(英文版)》2018,28(9):1215-1232

In concert with developments in global trade and energy resource transportation, there has been a marked increase in reliance on overseas shipping. Unimpeded marine transportation has therefore become a key issue which influences national maritime interests including the security of trade and energy resources. A strategic shipping pivot thus performs a vital controlling function for global shipping networks. In this study strategic shipping pivots are defined and subdivided into sea hubs, channels and areas. We then develop a model to identify strategic shipping pivots on a global scale. The results show that, depending on differences in location, function, and type, the concept of strategic shipping pivot permits the identification of both spatial and structural differentiation with respect to strategic hubs, corridors, and seas. Now 44 strategic hubs have formed across the globe. These hubs have become the control centers of local shipping network organization. At the same time, seven strategic corridors containing most shipping routes and transportation capacity connect important sea areas, and permit a high-degree of control over the transport of strategic materials. The strategic seas, the Caribbean, the Mediterranean, Southeast Asia, and the Pacific provide vital import and export pathways, so that the formation of strategic shipping pivots is mainly influenced by factors such as physical geographical conditions, the spatial distribution of socio-economic activities, business organization, technical progress, geopolitical patterns and geopolitical disputes. Physical geographical conditions provide the potential foundations for strategic shipping pivots, while the spatial distribution of socio-economic activities and communications determine the strategic value of these points. Finally, business organization, technical progress, and geopolitical disputes all function to strengthen the strategic mechanisms and the mutagenicity of strategic shipping pivots.  相似文献   

长三角地区港口腹地范围演化及其影响机制     

康译之  何丹  高鹏  孙志晶 《地理研究》2021,40(1):138-151

本文尝试将海港和内河港的腹地范围演化纳入统一的研究框架。运用场强模型划分2001年、2008年和2016年长三角主要海港和内河港口的直接腹地范围,分析其演化特征,总结演化最显著的两大龙头港口——上海港和宁波港的腹地演化影响机制。结果表明：① 港口场强分布特征是以三大海港为龙头形成三大高场强集聚区。② 港口直接腹地演化最明显的特征是宁波港扩张的腹地范围基本来自上海港收缩的腹地范围。③ 上海港的直接腹地范围不断被宁波港袭夺是因为上海港通过市场主导和行政协调的机制,扩展了沿着长江布局的内河港口群水水中转的间接腹地,而非直接陆地腹地;相反,宁波港主要依靠行政机制和逐渐强化的市场力量,使直接陆地腹地范围逐渐延展到浙江全省。  相似文献   

Effect of shipping activity on warming trends in the Canadian Arctic     

Hussain  Mian Sabir  Heo  Inhye  Im  Sujeong  Lee  Seungho 《地理学报(英文版)》2021,31(3):369-388

This paper presents a detailed account of the effect of shipping activity on the increasing trends of air temperatures in the Canadian Arctic region for the period of 1980–2018. Increasing trend of temperature has gained significant attention with respect to shipping activities and sea ice area in the Canadian Arctic. Temperature, sea ice area and shipping traffic datasets were investigated, and simple linear regression analyses were conducted to predict the rate of change(per decade) of the average temperature, considering winter(January) and summer(July) seasons. The results indicate that temperature generally increased over the studied region. Significant warming trend was observed during July, with an increase of up to 1℃, for the Canadian Arctic region. Such increasing trend of temperature was observed during July from the lower to higher latitudes. The increase in temperature during July is speculated to increase the melting of ice. Results also show a decline in sea ice area has a significant positive effect on the shipping traffic, and the numbers of marine vessel continue to increase in the region. The increase in temperature causes the breaking of sea ice due to shipping activities over northern Arctic Canada.  相似文献   

STUDY ON DEVELOPMENT STRATEGY OF SHIPPING CENTERS AND TRANSPORTATION NETWORKS IN THE YELLOW SEA RIM IN THE YELLOW SEA RIM     

JINFeng-jun 《中国地理科学(英文版)》2003,13(2):97-103

It is very important to establish cooperative mechanism to guarantee all members to develop their e-conomies in the Yellow Sea Rim. In this paper, the development strategies ofshipplng centers and transportation networkare discussed based on economic giobalization tendency. The results argue that a united transportation network should bebuilt in order to promote the economic competition of Northeast Asia in the world. As a key component of the economiccooperation, a hierarchical shipping centers network should be established with Hong Kong, Shanghai, Pusan, Koho,and Tokyo as cores. The authorities of China, Japan, R. O. Korea and D. P. B. Korea should make more efforts tobuild a set of cooperation institutions based on raising the transportation efficiency.  相似文献
