微观生产函数与总量生产函数的矛盾——技术再转换

根据“替代原理”和利润最大化的假定,新古典学派得出命题:利润率与人均资本量之间存在着反向单调关系。该命题在单一产品或同比例要素模型中无疑是正确的,然而一进入异质品模型就会面临“技术再转换”的悖论。一个重要的原因在于异质品模型中,在统一利润率的假设下,收入分配会影响相对价格,从而技术不能按人均资本量排序。“技术再转换”的悖论使新古典的总量生产函数受到质疑。

CONTRADICTION OF MICROECONOMIC AND AGGREGATE PRODUCTION FUNCTION

Based on the substitute principle and profit maximization,neo-classical economics get the proposition that the relationship between profit rate and capital stock per capita is negatively monotony.Though it is right when single product and same proportion of the factors,this proposition would face the paradox of "technological re-transform" when heterogeneity.One of the reasons is that with the heterogeneity and uniform profit rate,income distribution will affect the relative prices and so the technology can't be ordered by capital stock per capita."Technological re-transform" challenges the aggregate production function of neo-classical economics.
