项目摘要

The aims of this project are (1) to investigate the general relationship between the city size and the annual expenditure/revenue in the basis of data of all municipalities in Japan, througla this, (2) to show the evidence of agglomeration economies and the optimum size of a city in view of local public finance, and (3) to estimate quantitatively the effects of merger of municipalities on the local public finance.Trough this study for three years, I could achieve aims mentioned just above and publish many papers and a book, which were quoted at the discussion in academic associations and local governments.The main results are follows.(1) The per capita annual expenditures (logarithmic transformation) can be expressed at the quadratic, concave function of the population size (logarithmic transformation).(2) The per capita revenue (logarithmic transformation) which is independent from the national government can be expressed at the cubic, increasing function of the population size (logarithmic transformation). The per capita revenue (logarithmic transformation) which is dependent of the national government can be expressed at the quadratic, concave function.(3) We can find the economies of scale in cities which have less than 300 thousand of population, diseconomies of scale in lager cities. In towns and villages, we can find always the economies of scale.(4) The optimum size of a city in view of local public finance is about 20O〜300 thousand of population.(5) Through these results, the mergers of the Larger Areas for Municipal Cooperation which amount to 341 areas will reduce annual expenditures by 3700 bilion yen (about 13%) that is equal to the construction cost of high way from Tokyo to Okayama prefecture.

该项目的目的是（1）在日本所有文化实体的数据基础上研究城市规模和年度支出/收入之间的一般关系，通过此信息，（2）展示了促进集聚经济的证据，以及鉴于当地公共财政的最佳规模，以及（3），（3）估算了本地公共限制的效果。并发表许多论文和一本书，在学术协会和地方政府的讨论中引用。（1）人均年度支出（对数转换）可以在人口规模的二次，凹入功能（对数转换）中表达出来的二次凹入功能（对数转换）。人口大小的功能增加（对数转化）。依赖国政府的人均收入（对数转型）可以通过二次，凹面的功能来表达。（3）我们可以在少于30万人口的城市中找到规模经济，在落后城市的规模平整。在城镇和村庄中，我们可以总是找到规模的经济。（4）鉴于当地的公共财政的最佳规模，大约约30万人口。（5）通过这些结果，较大的市政合作领域的合并是341个领域的合并，相当于3700 Bilion YEN（约13％）的成本与最高量相比，这将减少341个地区的支出。
