GTAP Data Base是全球贸易分析项目的**,它是一个完整的、公开的全球数据库,包含完整的双边贸易信息、运输和保护联系。GTAP Data Base代表世界经济并被世界各地数以千计的人作为当代应用一般均衡对全球经济问题分析的关键来使用。

近的一个版本主要是以2004年、2007年和2011年为参考年份,以及140个地区的所有57个项目的商品。GTAP Data Base常用的是和GTAP模型和RunGTAP软件一起使用。**,用户必须使用Data Base提供的GTAPAgg(或FlexAgg)程序,汇集数据(区域、商品和捐赠)到所需的水平,然后使用GTAP或GTAPinGams模型来分析全球政策的影响(贸易、环境、**政策通常被检查)。
或者,用户可能想从GTAP Data Base中提取国家SAMs或I-O表,用于单个国家模型。如果您感兴趣的是GTAP Data Base的其他用途,我们建议您阅读GTAP Data Base is not页面的详细信息。 GTAP Data Base不是经济变量的关系数据库。只有对经济数据感兴趣的用户才能较好地服务于诸如世界银行发展指标、**货币基金组织的金融统计数据或粮农组织的农业统计数据等。GTAP Data Base上的数据准确地描述经济变量的大小,但它们是以服务于CGE建模集合表示的。
系统要求硬盘至少有256 Mb的内存,操作系统Windows 98, 2000, XP, Vista, 7 or 8或以上。The GTAP Data Base is NOTa repository of Input-Output tables. The GTAP Data Base is a consistent representation of the world economy in the year base of the current version. Underlying the data base there are national input-output tables, trade, macroeconomic, and protection data from several sources. The underlying input-output tables are heterogeneous in sources, base years, and sectoral detail, thus for achieving consistency, substantial efforts are made to make the disparate sources comparable. For these reasons, the objective of the GTAP Data Base is not to provide IO tables, but to facilitate the operation of economic simulation models ensuring users a consistent set of economic facts. Some users interested in particular SAM use utilities written by researchers in the network to extract them. Users building IO tables based on this information do that under their own risk, and are assumed to understand the limitations imposed by the process of data base construction.
