本文的中心内容是,运用因素递进构造公有经济发展中的收入差别理论模型,并提出理论假设。限于篇幅,对该模型和假说的验证留待以后讨论。分析的顺序是,通过逐一考察公有经济中与经济发展有关且影响收入差别的各主要因素的变动及其同收入差别的关系,最后导出总的理论模型和倒U假说。这里,首先分析劳动差别一生计剩余模型。 The main content of this paper is to construct a theoretical model of income inequality in the development of public economy by using factors and put forward theoretical hypotheses. Due to space limitations, validation of the model and hypothesis remains to be discussed later. The order of analysis is that by examining the changes of the main factors in the public economy that affect the economic development and affect the income disparity and their relationship with the income disparity, we finally derive the total theoretical model and the inverted U hypothesis. Here, we first analyze the remaining models of labor-livelihood.
