基于協(xié)調(diào)度模型的收入差距合理區(qū)間控制研究
[Abstract]:Since the reform and opening up, China's social and economic development has made great achievements, and the people's living standards have been significantly improved. But at the same time, the income gap of residents in our country is also widening, which has aroused the widespread concern of the public. A certain income gap in the course of economic development is a relatively common phenomenon. However, if this trend of expansion is allowed to continue to develop and reach the point of disparity between the rich and the poor, it will seriously hinder the coordinated development of the social economy. Then affect our country socialism modernization progress steady advance. This paper will explore the moderation of income gap as the focus of the full text. Considering the three aspects of economic growth, resource allocation efficiency and social equity and stability, this paper evaluates the moderation of income gap over the years in China. The specific research methods are as follows: first of all, in the process of measuring the income gap in China, the Gini coefficient, the Thiel index and the coefficient of variation are taken into account to measure the respective advantages of the income gap. Take the three as sub-indicators to build the income gap measurement index system, so as to make an accurate measurement of the income gap over the years in China; Secondly, from three aspects of economic growth, resource allocation efficiency and social equity and stability, this paper constructs an index system for evaluating the moderation of income gap, which covers 34 sub-indicators, namely, social and economic coordinated development index system. Thirdly, by constructing the coordination degree model between the income gap index and the socio-economic coordinated development index (economic growth evaluation index, resource allocation efficiency evaluation index and social equity and stability evaluation index). From 1993 to 2011, the author calculates the evaluation index of various kinds of static (dynamic) state moderation of China's income gap, and according to the results of the calculation, it concludes that the current income gap and various aspects of social and economic development in our country are still in a relatively coordinated state. Finally, according to the international classification standards on the degree of coordination, taking 0.95 (the lower limit of the "moderate" range) as the threshold, the results of the evaluation index of the moderation of income gap in China are screened. Taking the Gini coefficient value of the corresponding year in a moderate range as the sample object, the reasonable range of the final Gini coefficient is calculated based on the relevant statistical method [0.35% 0.40]. Based on the above empirical analysis, it is concluded that the income gap and various aspects of social economy in China are in a relatively coordinated and relatively adaptable state at present. However, after entering the 21st century, most of the Gini coefficients of our country fall to the right side of the reasonable range [0.35 / 0.40], which indicates that the income gap of the residents in our country is already on the large side, if we do not control it and let it develop, It will inevitably lead to disharmony and incompatibility with social and economic development. So at the end of this paper, aiming at the reality of our country, the author puts forward the combination policy of "one main and two wings" to control and narrow the income gap and bring it back to a reasonable range.
