Gini coefficient is a statistical index to measure the difference of income distribution put forward by Italian economist Gini at the beginning of the 20th century. Generally, 0.4 is regarded as the warning line of income gap in the world, and Gini coefficient above 0.4 indicates that the income gap is large and may cause many social problems; The Dankini coefficient reaches 0.5-0.6, indicating that the income distribution is highly disparity, and serious social unrest and social crisis are likely to occur.

China has been conducting income surveys for urban and rural residents respectively. Because the indicators and basic data are not unified, it is impossible to calculate the Gini coefficient which is unified throughout the country. In February of 20 12, according to the new standards, the National Bureau of Statistics rearranged the basic data of urban and rural households from 2003 to 20 1 12, especially the income data, and added the new statistical income data of residents in 20 12 to calculate the Gini coefficient of the national residents in the past decade.

Extended data

Although China's Gini coefficient is relatively high, it has not caused serious social problems or social unrest like some countries with high Gini coefficient, so "Gini coefficient index is not suitable for China" is a big misunderstanding.

China has maintained social stability with a high Gini coefficient, which is mainly due to the rapid economic growth and the improvement of the real life of low-income people. If some serious social problems are not effectively solved, once the economic growth slows down, various problems and contradictions may be highlighted, and social risks and crises may increase rapidly.
