摘要
基尼系数反映的是一个国家居民收入分配合理与居民收入平等程度的重要指标之一。近年,我国居民的基尼系数持续攀升,居民收入分配差距日益扩大,尤其是城乡之间、地区之间尤为明显。为此,笔者首先以动态的方式,利用线性拟合方程,拟合并预测了我国居民的基尼系数,说明其变动的趋势;其次,从历史的、政策的角度,分析我国基尼系数过高的原因,认为基尼系数过高与我国垄断有关,但与我国经济快速发展、经济社会体制快速转型的经济背景有根本性的关系。当今,我国居民的基尼系数已达到并超过国际警戒线,结合我国的国情,充分利用政策优势,改善城乡收入分配格局,缩小城乡间的收入差距,使我国居民收入差距处于合理的范围,处在库兹涅茨的倒U型的左半部分。
Gini coefficient is one of the important criteria to judge whether the national income distribution is under the reasonable condition, and measure the degree of equality in resident income. In recent years, Chinese resident Gini coefficient has kept rising with the gap of resident income increasingly widening, especially between urban and rural areas and between regions. Firstly, using linear regression equation, this article dynamically fits and forecasts the Gini coefficient of Chinese residents, and presents the trend of Gini coefficient. Secondly, from the historical and policy perspectives, this article discusses the causes of too high Gini coefficient, and concludes that it is related with the corruption and monopoly, but it has the fundamental relationship with China＇ s rapid economic growth and fast-going transformation of economic and social system. Nowadays, Chinese resident Gini coefficient has been on or above the international warning line. Considering China＇ s national situation, we should make full use of policy advantage to improve the income distribution pattern between urban and rural areas, narrow the income gap between urban and rural areas, so that Chinese resident income gap can be well within the reasonable range in the left of Kuznets inverted-U curve.
