基于层次分析法和信息熵的多准则指标选取

通过对经常项目的跨时最优现值模型进行扩展，将居民的消费习惯变量包含进了扩展模型并进行了实证检验.结果表明，模型的功效得到了显著改善，居民的消费习惯在中国经常项目的差额波动路径中起了重要作用.由于消费习惯的形成，居民更加关心消费的变化而不是消费水平，其跨时消费决策的结果则是储蓄大于投资.因此，缩小居民的收入差距、降低对未来的支出预期，逐步转变居民的消费习惯是调整中国经常项目差额波动的有效途径.

Multi-criterioned Index Selecting Method Based on AHP and Entropy Theory

Index selecting of a new equipment is often cumbered by the lack of testing samples and resources. A multi-criterioned index selecting method based on AHP and entropy theory is put forward after contrast Analytic Hierarchy Process (AHP), Dijkstra and rough set. In this method, indexes are compared by each other according to several basic criterions to build up judging matrix, which will be analyzed under Entrop theory to decide the power of each criterion. Subjective attitude of experts is also collected to be analyzed under G1 method to decide the power of criterions. Then original data will be summed by power of criterions. A example is given in the end of the paper. This method simplifies the index selecting by its objective comparison and none-sample-demand attribute.
