经济增长模型中Solow余值的研究

通过对生产函数的前提条件的理论分析,证明了在完全竞争条件下,“余值”不存在,Solow的假设性前提错误,但“余值”存在于现实之中的非完全竞争条件下。“余值”是内生的,不是外生的,其取值范围为[0,1/(α+β)],随价格偏离边际成本的程度δ增大而增大。狭义A的确切涵义既不是“知识进步”,也不是“智能进步”,更不是“全要素生产率”,而是与k,L密切关联,由市场的不完全竞争程度通过价格偏离边际成本,影响k,L的投入,进而影响α,β,最后影响经济增长,具有动态和影响“全方位”特征的变量。

A Research on the Residual Value of Solow in the Model of Economy Growth

By the analysis of premise of production function, this article proves the residual value, namely the error of assumption premise of Solow, doesn't exist under the condition of perfect competition market. However, the residual value does exist in the imperfect competition market of real world. The residual value is inherent, and its value range is [0,1/(α+β)].It increases with the difference between the marginal cost (δ) and the price. In a narrow sense, variable A is not defined as advance of knowledge, advancement of intelligence, or productivity of all elements, but kept close relations with k and L. The input of Randare influenced by the difference between marginal cost and price resulting from imperfect competition, and therefore the difference will affect, α,β and economy growth after all. To summarize, A is a dynamic variable which affects all orientation.
