摘要：

投入产出分析是分析产业间关联、制定经济发展计划和进行政策分析时一个非常有用的工具。但是,传统的投入产出分析往往存在以下假设:(1)固定的投入产出系数;(2)规模报酬不变;(3)对所有商品都存在需求;(4)配套给定的基础设施;(5)部门同质性假定。然而,投入产出系数会时不时地更新,某个计划期内投入产出系数的内生变化可以也应该被考虑进去。本文将从这些标准的假定出发,对投入产出技术进行一些衍生性讨论和拓展性分析。

Abstract:

Input-output analysis is a valuable and useful tool for understanding the interdependence within an economy, and for economic planning and policy analysis. However, conventional input-output analysis typically assumes:(1) fixed input-output coefficients; (2) constant returns to scale; (3) the desirability of all goods; (4) given fixed infrastructure, and (5) the homogeneity of goods. While it is true that input-output coefficients are updated from time to time, endogenous changes in the input-output coefficients within a planning period can and should be taken into account. Possible extensions of input-output analysis that allow these deviations from the standard as-sumptions are proposed.
