基尼系数是国际上常用的一种收入差距的测量指标,其数值在0～1之间。数值越高,收入分配的不均等程度越高。按照国际通常标准,基尼系数在0.3以下为最佳的平均状态,在0.3～0.4之间为正常状态,超过0.4为警戒状态,达到0.6则属于危险状态。改革开放以来,我国在经济增长的同时,贫富差距逐步拉大,综合各类居民收入来看,基尼系数越过警戒线已是不争的 Gini coefficient is a commonly used international income gap measurement, the value of 0 to 1 between. The higher the value, the higher the inequality in income distribution. According to the international common standard, the Gini coefficient is the best average state below 0.3, between 0.3 and 0.4 for the normal state, more than 0.4 for the alert state, reaching 0.6 is a dangerous state. Since the reform and opening up, while economic growth in our country has widened gradually, the gap between rich and poor has widened. According to the income of all kinds of residents, it is an indisputable factor that the Gini coefficient crosses the warning line
