The Regional Input Output Link Model of China
中国大区域间投入产出连接模型

The trade of goods and services among regions is described by the regional input output link model, which should be comprehensive balance for each sectors. Due to the natural resources, the production level of regions in China are very different, the research of regional input output models is an important topic. Generally, the regional input output link model is established based on the input output tables of all relative regions. But there are the import and export data of each sector in the regional tables only, the trade data for each sector among different regions can not be obtained. In this paper, some methods of establishing the regional input output link models are discussed. These methods can be used to analyze the trade among different countries.
