改革开放以来居民收入差距的实证分析——以江苏省为例

Empirical Analysis on Residents' Income Difference since the Reform and Opening-up——Taking Jiangsu Province as an Example

改革开放近40年来,江苏省城镇居民家庭人均可支配收入从1978年的288元增加到2017年的43622元,增长了150.47倍,年均增长13.74%;与此同时,农村居民家庭人均纯收入由155元增加到19158元,增长了122.60倍,年均增长13.15%。通过逐一实证分析可以发现,从基尼系数、城乡划分、区域划分、行业划分、收入阶层、不同经济性质单位来看,江苏省全省居民收入差距日渐扩大,接下来应完善收入分配制度,防止收入差距的进一步扩大。

In the past 40 years of reform and opening up,the per capita disposable income of urban residents in Jiangsu province has increased from 288 yuan in 1978 to 43,622 yuan in 2017,as an increase of 150. 47 times,and an average annual increase of 13. 74 percent. Meanwhile,the per capita household income of rural households＇ net income increased from155 yuan to 19,158 yuan,as an increase of 122. 60 times,and an average annual increase of 13. 15%. Through empirical analysis,we can see that from the perspective of Gini coefficient,urban-rural division,regional division,industry division,income class,and different economic nature units,the income gap between residents of Jiangsu province is gradually expanding. Next,the income distribution system must be perfected to prevent further widening of the income gap.
