收入分配对资本积累及投资结构的影响——我国二元结构下的三部门均衡模型

The Influence of Income Distribution on Capital Accumulation and Macroinvestment Structure: a Threesector Equilibrium Model Based on China's Dual Economic Structure

本文以我国二元结构为背景,从收入分配的角度,建立了资本积累、投资结构决定的数理模型,并以此分析资本积累、投资结构的影响因素。模型参数分析的主要结论是:①任何导致总消费需求上升的变化都会通过提高轻工业的供给能力而提高其资本存量的相对比重,以及资本积累的相对比重(即抑制投资重化);②任何提高消费品供给能力的技术进步通常都将降低稳定状态下轻工业资本存量,以及资本积累的相对比重(即促进投资重化)。

A mathematical model is built for the decision of capital accumulation and macro - investment structure in China from the angle of income distribution based on its dual economic structure. The relevant factors are analyzed according to the model. It is argued that：① any change that may cause the increase of consumption will certainly enhance the supply capacity of light industry and curb the investment unfavoring heavy industry; ②on the other hand, any innovation that may enhance the supply capacity of consumption goods will certainly promote the investment favoring heavy industry.
