GTAP Data Base不支持的功能
GTAP Data Base不是输入-输出表的存储库。GTAP Data Base是世界经济在当前版本年数据库的一致表现。数据库包含了多个数据来源的国家投入产出表、贸易、宏观经济和保护数据。潜在的输入-输出表在数据源、年份库和部门具体细节上是多种多样的,因此,为了实现一致性,我们作出了大量努力,使不同的来源具有可比性。由于这些原因,GTAP Data Base的目标不是提供IO表,而是为经济模拟模型的运行提供便利,以确保用户能够得到一致的经济事实。一些对特定SAM感兴趣的用户使用网络中的研究人员编写的实用工具来提取它们。基于这些信息用户根据自身的风险构建IO表,并假定理解数据库构建过程所带来的局限性。
GTAP Data Base不是经济数据的时间序列存储库。除了贸易数据之外,GTAP Data Base是关于消费、生产和贸易的一致数据的截面。一些用户认为将不同版本的数据绑定在一起会给他们带来时间序列的变化。我们强烈建议用户熟悉GTAP Data Base的构建过程,考虑到对于许多国家来说,基础的IO表不会从版本到版本的变化,大部分的变化来自于基于宏观经济或贸易变化的调整过程。
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、**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建模表示的。

What is the GTAP 9 Data Base?
The centerpiece of the Global Trade Analysis Project is the GTAP Data Base, a fully documented, publicly available global data base which contains complete bilateral trade information, transport and protection linkages. The GTAP Data Base represents the world economy and is utilized by thousands worldwide as a key input into contemporary applied general equilibrium (AGE) analysis of global economic issues. The current release, the GTAP 9 Data Base, features 2004, 2007 and 2011 reference years as well as 140 regions for all 57 GTAP commodities.
The GTAP Data Base is most commonly used with the GTAP Model and RunGTAP software. First, the user must aggregate the data (regions, commodities and endowments) using the GTAPAgg (or FlexAgg) program provided with the data base to the desired level and then use with the GTAP or GTAPinGams model/s to analyze the impact of global policies (trade, environmental, migration policies are commonly examined). Alternatively a user may be interested in extracting country SAMs or I-O tables from the GTAP Data Base for single country models. If you are interested in these alternative uses of the GTAP Data Base, we suggest you read through the points detailed on this page about what GTAP Data Base is not.

GTAP Summary in Excel Programs - The 'GTAP Summary in Excel Programs' are a suite of programs designed to improve access to the GTAP Data Base for non-GEMPACK users. It has been developed by the Productivity Commission, building on previous work by GTAP and enables the generation of Excel workbooks containing a summary of each country's economic statistics in individual worksheets. Registered members of the GTAP website may access the GTAP 7 Data Base Summary Matrices as well as the GTAP 6 Data Base Summary Matrices.
GView - This free utility may be used to look at aggregations of the GTAP 6 Data Base.
GTAP 10 Data Base Documentation chapters 1 and 2 are particularly useful for new users to see how what is included in the GTAP Data Base and how it was structured. The GTAP Data Base is designed to be used with the GTAP Model and is typically run through the RunGTAP software. Before running the model, the user should aggregate the data (regions, commodities and endowments) using the GTAPAgg2 (or FlexAgg) program provided with the data base to the desired level and then use with the economic model (e.g., GTAP or GTAPinGAMS) to analyze the impact of global policies (trade, environmental, migration policies are commonly examined). Alternatively a user may be interested in extracting country SAMs or I-O tables from the GTAP Data Base for single country models.
