投入产出系数修正方法

Revision Method for Input-Output Technical Coefficients

在Ｒ．Ａ．Ｓ以及文刊［１］修正投入产出系数方法的基础上，进一步摆出３个修正公式，其中第２、第３修正公式能一次性得到最优替代乘数和制造乘数的积的解析表达式，无须进行迭代修正，具有工作量少，操作方便等特点．

Based on the R.A.S method and improvements given by paper[1], this paper proposes three revision formula of input-output technical coeffcients,which have many advantages such as less computation convenience to application and no iterations. Besides, the most important contribution of the new methods rest with getting the analytical substitution and manufactruing multiplers.
