Abstract: By totally examining the principles of the stock models and all of the rows, this paper gets the following outcomes: the stock models are essentially equal-dimensions and partial closed; the models shows crowding-out effects on final goods and spill-over effects on added values.

Key words: inputs and outputs, occupation model, economic stock

摘要： 在全面考察模型构造原理的基础上,通过分别对模型进行列向、行向的深入分析表明,投入产出模型的实质是等维局部闭模型,模型对最终产品具有挤出效应,对增加值具有溢出效应。
