Decomposition of Brazil’s per capita income growth: a regional-sectoral approach

Abstract The article measures the determinants of the Brazil's per capita income growth in the 2004-15 period, based on the role of productivity and variables related to the labor market and the demography. The investigation is carried out jointly in a regional (by Major Regions) and sectoral approach (contribution of each activity of the productive structure to the growth of each geographical unit). The role of productive efficiency and structural changes in the composition of employment and relative prices in this growth is highlighted. The article brings some contributions to the literature, mainly due to the empirical approach not yet explored within the regional and sectoral context. The results indicate important differences in the contributions of each component of the decomposition depending on the geographical unit analyzed, as well as relevant sectoral heterogeneities within and between such units.

摘要 本文基于生产率、劳动力市场与人口统计学相关变量的作用，探析2004至2015年巴西人均收入增长的影响动因。本研究同时采用区域层面（按巴西主要大区划分）与行业层面的分析范式，即探究生产结构中的各经济活动对各地理单元增长的贡献程度。本研究着重阐释了生产效率、就业结构变迁与相对价格在此次增长过程中的作用。本文为相关学术领域的文献作出了一定贡献，这主要得益于其采用了此前在区域与行业结合的分析框架中未曾被使用过的实证研究方法。研究结果表明，分解得到的各组成部分的贡献度因所分析的地理单元不同而存在显著差异，同时在各地理单元内部及单元之间均存在显著的行业异质性。
