Location choices of households and industries and the location inequilibrium in an economy with aging population and declining birthrate

我分析了在人口老龄化和出生率下降的经济中家庭和产业的区位选择。首先，我分析代际生活安排（父母和孩子是否共同居住）。在一个人口老龄化和出生率下降的经济体中，同样的代际生活安排往往会代代重复。这使得区域间移徙停滞不前。其次，将人力资本密集型产业纳入模型，分析了人力资本积累与产业区位选择的关系。该结果与日本各地区大学入学率的实际差距相吻合。产业集聚格局更可能呈现多极化。

I analyze the location choices of households and industries in an economy with agingpopulation and declining birthrate. First, I analyze intergenerational living arrangements(whether or not a parent and child co-reside). In an economy with aging population anddeclining birthrate, the same intergenerational living arrangement tends to be repeatedfrom generation to generation. This makes interregional migration stagnant. Next, Iincorporate industries which intensively employ human capital in this model, and analyzethe human capital accumulation and the location choice of the industries. The results fitthe actual gap in university entrant rate among regions in Japan. The agglomerationpattern of the industries is more likely exhibit multi-polarization.
