摘要
本文在Ｒ·Ａ·Ｓ以及文献［１］修正投入产出系数方法的基础上，进一步提出一种对数最小二乘修正方法。该方法能一次性得到最优替代乘数和制造乘数的解析表达式，无须进行迭代修正，具有工作量小、操作方便等优点。
Based on R·A·S method and its improvements given by paper[1],this paper proposes a new logarithmicleast square revision method of input-output technical coefficients. Compared with the present revision meth-ods,the new method has many advantages such as less computation,convenience to application and no itera-tions,etc. Besides,the most important contribution of the new method rests with getting the analytical substi-tution and manufacturing multipliers.
