To solve the problem that the present non-linear input-output models are unfit for calculation and application, based on the year-of-1973-1999 Chinese input-occupancy-output tables at constant price, this paper chooses 47 important coefficients with an influence method.
为了解决目前非线性投入产出模型可计算性与可应用性较差的问题,该文在1973-1999年中国不变价投入占用产出表的基础上,采用影响域法选取了47个主系数,然后应用回归分析的方法,得到了各主系数的非线性函数表达式,建立了主系数非线性的投入占用产出模型。
This paper brings forward losing information method to identify important coefficients of national economic sub-system,which is different from major four methods that are all aimed at national economic main system.
目前在投入产出模型中四种常用辨识主系数的方法都是针对国民经济主系统而言,而随着我国经济的发展,一些具有相同经济特征的部门组成的国民经济子系统正在国民经济中的地位日趋显著,辨识国民经济子系统的主系数也就显得尤为重要。
