Interest in regional convergence in mean incomes has been rekindled by findings that suggest a shift from convergence to divergence. While the majority of existing research has explored convergence in mean incomes, this research focuses specifically on the convergence/divergence of interpersonal income distributions across regions, referred to throughout the study as comparative inter-regional inter-personal income distributions (CIRIPID). The findings suggest that CIRIPID, as measured by the Gini coefficient, converge across countries, but that heterogenous trends are visible within countries. The results highlight that in some countries regions are becoming equally more unequal, while others see regional Gini coefficients trend towards a lower level of inequality. The study also explores the impact of systems of government on CIRIPID. In addition, the study draws on the convergence club methodology to identify heterogeneous CIRIPID convergence paths within countries.

区域层面的收入不平等是否趋同？来自 LIS 数据的证据

研究结果表明，地区平均收入趋同已从趋同转向分化，这重新激起了人们对区域平均收入趋同的兴趣。虽然大多数现有研究都探讨了平均收入的趋同性，但本研究特别关注跨地区人际收入分布的趋同/发散，在整个研究中称为比较性地区间人际收入分布（CIRIPID）。研究结果表明，以基尼系数衡量的 CIRIPID 在各国之间趋同，但各国内部的异质趋势也很明显。结果强调，在一些国家，地区不平等同样变得更加不平等，而另一些国家则认为地区基尼系数的不平等程度趋于降低。该研究还探讨了政府系统对 CIRIPID 的影响。此外，该研究还利用趋同俱乐部方法来确定各国内部异构的 CIRIPID 趋同路径。
