Decomposing the Induced Income Changes in Input‐Output Models
证明投入产出模型中第一类和第二类收入乘数在各行业间成比例，并分解了其差异的来源，对理解区域经济乘数效应有参考价值。
Abstract This paper demonstrates formally that type I and type II income multipliers are proportional across all sectors and that in any input‐output model, the difference between the multipliers can range from zero to a maximum of the reciprocal of one less the propensity to consume locally. The conditions which lead to these two extreme values are discussed. For intermediate situations, the difference is decomposed into proportions attributable to final payments and imports.
