使用为本研究构建的新数据集，分析了2010-2017年期间印度尼西亚34个省和514个地区的人均收入时空动态。首先，探索性空间分析表明，空间自相关仅在地区一级显着，并且从2013年到2017年似乎是稳健的。因此，在这一级，空间过滤模型用于将收入分解为空间独立的组成部分和空间残差。其次，通过分布收敛框架的透镜，发现空间独立的组成部分比原来的收入变量表现出更少的内部流动性。当分析Beta和Sigma收敛时，发现过滤变量的收敛模式较强，过滤数据的收敛速度也较高。因此，有人认为，邻居效应发挥了重要作用，在地区一级的收入收敛的速度放缓。就各省而言，报告了贝塔趋同，分布趋同框架表明，分布高端至少形成了三个分布内流动性高的俱乐部。文章最后将这些发现与一些合理的政策干预措施联系起来。
Using a novel dataset constructed for this study, the spatio-temporal dynamics of income per capita across 34 provinces and 514 districts in Indonesia over the 2010–2017 period are analyzed. First, an exploratory spatial analysis suggests that spatial autocorrelation is only significant at the district level, and it appears to be robust from 2013 to 2017. Consequently, at this level, a spatial filtering model is used for decomposing income into a spatially independent component and a spatial residual. Next, through the lens of a distributional convergence framework, it was found that the spatially independent component shows less intra-mobility than the original income variable. When analyzing beta and sigma convergence, strong converging patterns are found for filtered variables and the speed is higher for the filtered data. Thus, it is argued that neighbour effects have played a significant role in slowing the pace of income convergence at the district level. In terms of provinces, beta convergence is reported and the distributional convergence framework suggests the formation of at least three clubs with high intra-distribution mobility for the upper end of the distribution. The article is concluded by relating these findings to some plausible policy interventions.
