Abstract

In depopulating cities, vacant houses and lots are common throughout the urban area, creating low-density urban areas that can lead to inefficiencies in public services and financial deterioration for municipalities. However, despite some studies demonstrating the relationship between population density and public expenditure, no generalized conclusion regarding the essential effect of reducing public expenditure has been reached. Consequently, no method for rationally setting a population density as a performance target for municipalities when developing compact city planning has been established. Thus, this study used the cross-sectional data from Japanese municipalities and the exponentiation regression equation, to determine the strong relationship between population density and per-person public expenditure (PPPE). The findings are particularly noteworthy for municipalities that grew under a nationwide uniform city planning and accounting system, as they provide valuable insights into the generalization of the public expenditure reduction effect. Furthermore, this study developed a method using the exponentiation regression equation, which demonstrated an L-shaped trajectory indicating that PPPE increases at an accelerating rate when population density falls below a certain threshold. Municipalities can evaluate the efficiency of public expenditure simply by applying their population density to the regression equation. They can also verify population density as a performance target. Furthermore, this study revealed the turning point of population density at which the acceleration in the increase in PPPE begins, implying that municipalities can expect a grace period until the turning point.

低城市密度会增加市政支出吗?人口密度作为日本紧凑型城市规划的绩效指标
在人口减少的城市,空置房屋和地块在整个城市地区都很常见,造成了低密度的城市地区,这可能导致公共服务效率低下和市政当局的财政恶化。然而,尽管有一些研究证明了人口密度与公共支出之间的关系,但没有得出关于减少公共支出的本质效果的一般性结论。因此,在制定紧凑型城市规划时,没有办法合理地设定人口密度作为市政当局的绩效目标。因此,本研究使用来自日本各市的横断面数据和指数回归方程来确定人口密度与人均公共支出(PPPE)之间的密切关系。对于在全国统一的城市规划和会计制度下发展起来的城市来说,这些发现尤其值得注意,因为它们为公共支出削减效应的普遍化提供了有价值的见解。在此基础上,利用指数回归方程推导出了PPPE在人口密度低于一定阈值时加速增长的l型轨迹。市政当局可以简单地通过将其人口密度应用于回归方程来评估公共支出的效率。他们还可以验证人口密度作为绩效目标。此外,本研究揭示了人口密度的拐点,在拐点处PPPE的增长开始加速,这意味着在拐点到来之前,市政当局可以期待一个宽限期。

期刊介绍: Journal of Urban Management (JUM) is the Official Journal of Zhejiang University and the Chinese Association of Urban Management, an international, peer-reviewed open access journal covering planning, administering, regulating, and governing urban complexity. JUM has its two-fold aims set to integrate the studies across fields in urban planning and management, as well as to provide a more holistic perspective on problem solving. 1) Explore innovative management skills for taming thorny problems that arise with global urbanization 2) Provide a platform to deal with urban affairs whose solutions must be looked at from an interdisciplinary perspective.
