A Study on the Trade Effect of the Implementation of CEPA

2004年1月1日，CEPA正式生效，标志着内地和香港两地的贸易发展进入了一个新阶段。作为中国入世后签署的第一份自由贸易法案，CEPA旨在减少或取消内地与香港间所有货物的关税和非关税壁垒，实现服务贸易自由化，促进投资便利化。CEPA的签署，标志着内地与香港的合作开始从以往的由民间推动，企业主导的松散型模式逐步向着由政府推动，双方协调发展的制度化建设模式转变，必然会对两地经济产生深远的影响。本文基于区域经济一体化理论，分析了香港和内地经贸现状，研究内地和香港两地的货物贸易和服务贸易的总体规模、贸易比重、贸易结构和贸易方式。本文从实证角度出发，运用巴拉萨模型，贸易开放度等工具，分析了CEPA自签署...On January 1, 2004, CEPA came into effect, marking the trade relationship between the Mainland and Hong Kong has entered a new stage. As China's first free trade bill after accession to the WTO, CEPA aims to reduce or cancel all the goods tariff and non-tariff barriers between the Mainland and Hong Kong, achieves liberalization of trade in services and promotes investment facilitation.

Zooplanktonic diversity in the western Pacific

西太平洋区是全球海洋生物种源中心,许多类群的最高物种多样性都出现于该区域,因此,在该区开展种类多样性的研究不仅重要和必要,而且具有在跨国尺度上进行综合管理和相互合作的迫切性。本文在西太平洋的浮游动物样品鉴定分类、编目、文献资料整理和分析的基础上,记录和编入西太平洋10个浮游动物类群2,658种(含亚种),隶属于206科675属,其中水螅水母类99科251属697种,栉水母类12科22属59种,浮游软体动物14科35属86种,介形类8科89属416种,桡足类51科156属908种,糠虾类4科58属202种,磷虾类2科8属56种,十足类8科22属105种,毛颚类5科8属48种,被囊类5科26属81种。The western Pacific region has been operating as a centre for the origin of marine biodiversity: the richest diversity of many marine taxa was found in these waters.Therefore,biodiversity research and con-servation efforts in this area are necessary in order to promote the integrative and international management of this resource.The present work is a compilation of numbers of all the families,genera and species of ma-jor taxa of zooplankton known in the western Pacific Ocean(106°–150°E,0°–44°N).In all,2,658 zooplank-tonic species(including subspecies) belonging to 206 families and 675 genera have been recorded from taxonomic identifications and literature,99 families,251 genera and 697 species belong to the Medusozoa,12 families,22 genera and 59 species to the Ctenophora,14 families,35 genera and 86 species to the pelagic Molluscs(Pteropoda and Heteropoda),8 families,89 genera and 416 species to the Ostracoda,51 families,156 genera and 908 species to the Copepoda,4 families,58 genera and 202 species to the Mysidcea,2 fami-lies,8 genera and 56 species to the Euphausiacea,8 families,22 genera and 105 species to the Decapoda,5 families,8 genera and 48 species to the Chaetognatha,5 families,26 genera and 81 species to the Tunicata.908专项“中国海洋生物种类名录和图谱”(908-ZC-II-02)和908专项海洋生物样品库;科技部基础工作专项“我国和邻近西北太平洋海洋生物物种编目和分布图集编制”(2006FY220700
