Disaggregating Input-Output Models
给出一个通用解法，利用已有模型构建时被合并的部分活动信息，以少量计算构建更细分的投入产出模型，解精确且显式，并详细讨论了最常出现的将一个部门分解为两个的问题。
A general solution is given to the problem: with little computation, construct a more disaggregated input-output model from an available model, using information about some activities that were aggregated when the available model was built. The solution is exact and explicit. When only partial information is available, the exact solution guides its user to inexpensive and precise sensitivity analysis. Detailed consideration is accorded to the solution of the most frequently occurring problem: the disaggregation of one sector into two. 14 references.
