Interregional Income Inequality in the Pre- and Post Economic Crisis periods in Indonesia

这项研究以部门间/区域间结构和区域间要素流动为基础，探讨了印度尼西亚和日本区域间收入不平等的因素。研究发现，生产率差异部分是该区域具体部门间生产率差异的结果，它在很大程度上决定了整个观察年份的区域间收入不平等，无论是在1988年经济危机之前和之后，还是在战后日本经济。此外，调查还发现，资源丰富的爪哇以外省份生产率较高，但资本积累较低，因此区域间资本流动效率低下，有助于国家增长。东爪哇和雅加达的情况正好相反，这两个省份都是爪哇岛的高度工业化省份。

This research explored the factors contributing to the interregional income inequality in Indonesia and Japan, based on the intersectoral/interregional structure and interregional factor mobility. It found that the productivity differential component, which is a result of the region's specific sector-by-sector productivity differentials, largely determines interregional income inequality throughout the entire observed years, both before and after the economic crisis of 1988 and postwar Japanese economy. Further, it found inefficient interregional capital mobility contributing to national growth, based on the factual finding that the resource-rich off-Java provinces had higher productivity but lower capital accumulation. The reverse is true of East Java and Jakarta, which are highly industrialized provinces in Java Island.
