GTAP Data Base全球贸易分析数据库
GTAP Data Base是什么？
GTAP Data Base是全球贸易分析项目的核心，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。首先，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。
