基于C－D函数的变系数动态投入产出模型

A Time-varying Coefficient Dynamic Input-output Model Based on Cobb-Douglas Function

将Ｃｏｂｂ－Ｄｏｕｇｌａｓ函数应用于投入产出模型中消耗系数ａ＿（ｉｊ）（ｔ）和资本系数ｂ＿（ｉｊ）（ｔ）的确定，提出了一种新的时变结构系数动态投入产出模型的建模方法。

Applying Cobb-Douglas function to determine the technical coefficient a_(ij)(t) and capital coefficient b_(ij)(t),the authors propose a new model-time-varying structure coefficient dynamic input-output model.
