本文从人口和城市产业结构两个方面考察了1980 - 2010年日本经济的演变。随着20世纪70年代农村向城市转型的结束，日本通过周边城市的整合经历了第二阶段的城市化。这导致在审查期间，一组核心城市的人口平均增长率高达24%。与此同时，城市的产业构成也发生了重大变化：平均而言，一个城市在1980年有35%的制造业（三位数水平）到2010年已经离开，而一个城市在2010年有30%的制造业在1980年不在同一个城市。值得注意的是，人口和产业在城市间的大量迁移发生的同时，城市的规模和工业构成之间保持了一种简单而刚性的关系，其特点是存在工业的城市的数量和平均规模之间大致具有恒定的弹性。本文讨论了这种持续规律的政策含义和可能的潜在机制。
This paper investigates the evolution of the Japanese economy between 1980 and 2010 with regard to the population and industrial structure of cities. With the rural-to-urban transformation settling by the 1970s, Japan experienced the second stage of urbanization through the integration of nearby cities. This led, on average, to a disproportionately high population growth rate of 24% for a set of core cities during the review period. At the same time, cities experienced substantial changes to their industrial composition: on average, 35% of the manufacturing industries (at the 3-digit level) present in a city in 1980 had left by 2010, while 30% of manufacturing industries located in a city in 2010 had not been present in the same city in 1980. Remarkably, this substantial relocation of populations and industries among cities took place while a simple yet rigid relationship between the size and industrial composition of cities was preserved, characterized by the roughly constant elasticity between the number and average size of cities in which an industry was present. This paper discusses the policy implications of this persistent regularity and the possible underlying mechanisms.
