The Choice of Model in the Construction of Input-Output Coefficients Matrices
基于不变性和平衡性公理，从理论上解决了投入产出系数构建中多种模型的选择问题，并指出商品技术模型是唯一符合公理的方法。
The construction of input-output coefficients on the basis of flow data is complicated by the presence of secondary outputa.Seven methods to deal with this problea coexist.For example, the U.S. input-output requirementa tables are based on the so called industry technology model, Japan adopta the so called Stone method, while the tablea of the Federal Republic of German,y are based on the ao called commodity technology model.This paper aettlea the choice of model on the ground of theory.It postulatea invariance and balenCe axioms and proceeda to characterize one of the methoda to conatruct inputoutput ccefficients.The comaodity technology model i s aingled out.
