连环替代法的修正及数学推导

The modification and mathematics deduction of interlocking substitution

连环替代法在经济分析中运用非常广泛,但它的一个明显缺陷是各因素的排列顺序事先设定,倘若改 变一下顺序,各因素对指标的影响就会发生显著变化.在引进微分分析之后,就可以消除由于因素排列的不同所造 成对指标的不同影响,使连环替代法在经济分析中更科学、更客观.

The usage of the Interlocking Substitution is very widely in econcmic analysis. But one of its striking theorical faules is the preestablished arrangement of all factors. Suppose to change the order of the arrangement, the notable change would be happened by the influence of all factors to the index. After introducing the infinitesimal calculus analysis, the influence of the arrangement which is caused by the factors can be eliminated, so that the interlocking substitution can be more scientific and objective in the economic analysis.
