建设中老缅泰国际合作开发区营造景洪市立体开放口岸系统 总被引:1,自引:0,他引:1
本文论述了中老缅泰国际合作开发区建设是澜沧江—湄公河流域开发的优先启动区,是南南合作的新模式,对推动中南半岛次区域合作发挥着先导功能。景洪作为中国西南边境城市,在未来次区域合作中将升格为枢纽城市之一,因此,其开放度要不断扩大,在已具有的国家一类水运口岸基础上,要继续营造国家一类航空口岸、公路口岸,并在跨世纪建造昆明—曼谷铁路时,设置国家一类铁路口岸,同时在中缅240界桩两侧开辟新型的边境贸易旅游区,构筑景洪市全方位立体型开放系统。 相似文献

Since the Tumen River Area Development Project(TRADP) was launched in 1991, Hunchun city located between North Korea and Russia
along the river corridor, has become an important and unique border city. Hunchun, formerly a strategic military city, is
emerging as an international trade linkage center through Satouz and Quanhe on the North Korea side and through Changlinzi
on the Russian side. Furthermore, the establishment and operation of the Hunchun Border Economic Cooperation Zone (HBECZ)
in the city is becoming the main source of the growth, providing a new role for the border city. Its underlying economic momentum
comes from the combination of the Chinese-Korean labor force and foreign investment and technology transferred from Korea,
Japan, and others.
The most important expected new role for Hunchun is as a new 21st century entrepot connection between the Pacific rim and
Eurasia by rail and trunk lines, and as a new regional center of the border region based on both a newly generated urban subsystem
and the increasing informal sector of cross border business. However, there are many obstacles to overcome in the near future,
such as the possible military tensions among the three border nations, the guarantee of free entries and sailing on the Tumen
river, and agreements concerning environmental conservation.

In 2001, the National Oceanic and Atmospheric Administration (NOAA) and the Ministry of Maritime Affairs and Fisheries Integrated Coastal and Ocean Resources Scientific and Technical Arrangement was signed to pursue scientific and technical cooperation in integrated coastal and ocean resources management in the mutual interest of the participants. Over the last 6 years, the cooperation has been very beneficial, particularly for advancing marine science and management programs in Korea, such as Deep Sea Aquaculture, Sea Grant College Program, Marine Protected Areas, and Ocean Observations. The benefits to NOAA from the cooperation include Deep-ocean Assessment and Reporting of Tsunamis (DART) buoys, ocean and coastal observations, GEOSS program, and Global Program of Action. Also the cooperation has spillover effects on other ocean science and technological arrangement between US and Korea. This article reviews purpose, obstacles, and achievement of the cooperation and suggests recommendations for the future steps. 相似文献

Stakeholder participation is vital when introducing and implementing ecosystem-based management (EBM) at any scale. This paper presents the results of a survey covering four European Regional Seas (Baltic Sea, Black Sea, Mediterranean Sea and North-East Atlantic Ocean) aimed to collect stakeholders׳ perspectives on their Regional Sea governance to implement the European Union (EU) Marine Strategy Framework Directive (MSFD). In this survey, drivers of good governance including stakeholder involvement, willingness and capacity to cooperate, efficiency, institutional ambiguity and decision-making were explored. The results indicate a clear gap in perception between the current, the ideal and the foreseen situation regarding the implementation of the MSFD. The preferences for the future governance structures vary between stakeholders and across seas although some similarities can be found. Based on the results of the survey, this paper concludes that tailor-made rather than off-the-shelf solutions will be needed to accommodate regional cooperation in the European marine environment for implementing ecosystem-based management under the MSFD. 相似文献

中国境外经贸合作区的建设是国内特殊经济区发展经验在空间上的延展。基于东道国独特的发展条件,需要将国内园区的建设经验进行调整,再运用到中国境外经贸合作区以适应东道国本地化发展。构建政策移动的理论框架,采用案例分析和比较研究法,以天津经济技术开发区与中埃·泰达苏伊士经贸合作区为例,将国内园区与境外经贸合作区的相关政策进行对比分析,验证政策在不同国家“土壤环境”中的适应性。研究发现:① 根据政策施行的影响因素和不同作用,政策移动可以分为政策移植、政策调试和政策创新;② 规划建设经验、运营管理经验、环保政策、人才政策等可直接进行政策移植;发展模式和文化政策要进行政策调试;法规政策、晋升政策和优惠政策需要进行政策创新;③ 园区的共性体现在国内园区成熟经验的借鉴、人才的培育与储备、园区生态环境的保护以及基础设施和配套设施的完善;④ 园区的个性体现在文化的求同尊异、园区品牌的打造、晋升制度的创新和协调机制的建立等。创新性地运用政策移动性理论将国内和国外园区进行关联研究,揭示了境外经贸合作区的移植、调试和创新国内园区政策的过程,深化了政策移动理论的内涵,丰富了境外经贸合作区的理论研究成果。 相似文献

地理国情监测是新时期测绘地理信息部门对基础测绘工作的拓展和延伸,其跨行业、跨部门、跨学科、跨区域等特性,要求测绘地理信息部门必须完善各项工作机制,强化部门间横向合作、系统内纵向协作等机制建设,同时调动行业力量,全面配合地理国情监测的顺利开展。本文将在以往地理国情监测理论研究和实践的基础上,重点对监测、监督和监管3个阶段测绘地理信息部门及相关部门的任务分工和合作机制建设,各级测绘地理信息部门的职责分配和统筹规划、成果汇交与发布等协作机制建设,以及如何发挥企业在科技创新和地理国情监测任务实施方面的作用等开展一些初步分析和探索。 相似文献
