Location advantages of ports refer to the current developments of ports based on their conditions,such as geographic location,traffic accessibility and hinterland economy,etc.,and the spatial pattern of ports'location advantages reflects the spatial distributions,the regularities and the correlations among their conditions for development.A good under-standing of the spatial patterns of ports'location advantages can help to better identify the relative advantages of ports,position ports'functions and make strategic plans for develop-ment.This paper selected 1259 ports from 63 countries along the Maritime Silk Road as re-search objects and builds an accessing model to analyze their location advantages on the bases of six factors:the influence of strategic shipping pivot,the competitiveness of port lo-cation potential,port network status,the influence of city,the influence of traffic trunk,and road network density in hinterland.The study has the following three findings.Firstly,the location advantages of ports show a"high-low-high"distribution pattern from the west to the east,displaying an obvious"core-periphery"regionalized distribution.Secondly,most ports have high location advantages,mainly located in Strait of Malacca,the United Arab Emirates,northern Mediterranean coastal region and China-Japan region,the top 10 ports are mainly located in Singapore,China,Malaysia and Japan,indicating that the shipping industry in Asia-Pacific region has stepped to the far front of the global competition;slow economic growths,wars,far away from the Belt and Road countries or bad climate have low location advantages,mainly located in African coastal areas,Oceania,Northeast Europe and Russia.Thirdly,compared with the landward location advantages,the seaward location advantages have a higher influence,and different indicators of location advantages have different influ-ences on the evaluation results,the competitiveness of port location potential being the core indicator. 相似文献

利用1997-2006年我国分省区分年度数据,实证分析劳动力质量对外商直接投资区位选择的影响。采用广义最小二乘法拟合混合数据模型的结果表明,在控制了劳动力成本、市场规模、基础设施和开放度等变量后,劳动力质量与外商直接投资总额存在显著的正相关,这说明劳动力质量已成为决定外商直接投资区位选择的重要因素。20世纪90年代中期以来,在外商直接投资技能升级的背景下,区域比较优势已由低成本劳动力转变为高质量劳动力,大力提高劳动力质量是吸引新一轮外商直接投资的重要战略措施。 相似文献

在城市化进程中,城市测量是城市建设的基础和重要环节。随着全球定位系统(GPS)技术的快速发展,CPS RTK(Real Time Kinematic)测量技术也日益成熟,RTK测量技术逐步在测绘中得到应用。GPS RTK测量技术因其精度高、实时性和高效性,使得其在城市测绘中的应用越来越广。本文结合作者多年的相关工作经验总结了RTK测量在城市测量中的应用,并对RTK测量与传统测量作一个综合的比较分析。 相似文献

在经济全球化的新形势下,台湾海峡两岸经济发展的差距正在缩小,科技合作的空间正在扩大.海峡两岸,唇齿相依,在台风预警、应急救援、地震灾害预报、海底资源勘探开发、通信光缆安全保障等诸多领域,可以优势互补,互利双赢.在客家、玛祖和疍民等面向海洋的蓝色文明的文化交流方面,底蕴深厚、源远流长.当海岛经济发展到比较成熟的阶段时,趋向回归大陆,乃是历史的必然规律. 相似文献
