摘要：

收入极化通常是用家庭调查数据来衡量的，但这些数据往往缺失了高收入群体的数据。本文结合2002年、2013年和2018年中国家庭收入调查项目数据和中国高收入数据库的数据，研究2002年至2018年中国收入极化的趋势、原因和异质性。我们的主要发现如下：（1）当加入高收入群体数据后，三个调查年份中的收入极化程度显著增加，但收入极化趋势不会受到影响。（2）2002年至2013年间，收入极化现象显著增加，主要原因是贫困居民的收入极化加剧。2013年至2018年期间收入极化保持稳定，主要原因是中等收入群体的扩大，收入向中间分布的趋同主要归因于穷人，而非富人。（3）2018年，男性、受教育程度高和城市居民的收入极化程度分别高于女性、受教育程度低和农村居民。

Abstract

Income polarisation is normally measured using household survey data, but such data often provide insufficient coverage of top incomes. This paper combines data from the Chinese Household Income Project and Top Incomes in China databases for 2002, 2013, and 2018 to study the trends in, reasons for, and heterogeneity of income polarisation in China between 2002 and 2018. Our main findings are as follows. (1) Introducing external top-income data increases the estimated level of polarisation in each of the three surveyed years, but polarisation trends are not affected. (2) Polarisation increases significantly between 2002 and 2013, due to a rise in polarisation among poor residents. Polarisation remains stable between 2013 and 2018, due to the expansion of the middle-income group; the convergence to the middle of the distribution is attributable mainly to the poor, rather than the rich. (3) In 2018, levels of polarisation are higher among male, well educated, and urban residents than among female, less educated, and rural residents, respectively.
