Abstract：

As the impact of population decline and urban shrinkage becomes increasingly evident, there is a growing concern about achieving smart and sustainable development for expanding urban structures. This paper focuses on the urban facility location plan as a nationwide institutional framework for compact city structures in Japan. The paper selects and analyzes 21 representative model cities to identify the essential elements for the formation of urban structures for compact cities, and practical solutions for concentrated areas. The findings are as follows. Firstly, when establishing an urban function promotion area with hierarchical significance within a city, the relationship with the urban master plan is the most important factor, while the access to public transportation is a frequently used criterion. Rather than being separate, it is valid to be considered to base on relationship with the transportation hubs within the urban master plan. Secondly, in setting up a residential promotion area, access from the urban function promotion area and public transportation axis, as well as maintaining an appropriate population density, are usually considered to provide objective explanations. Additionally, specific unique situations in the city are also considered. Based on these findings, some insights into optimizing urban spatial structures and formulating territorial spatial planning for shrinking cities in China are proposed.
