<p>To address the aging of public facilities, the Ministry of Internal Affairs and Communications requested municipalities to formulate a “Comprehensive Management Plan for Public Facilities and Infrastructure” in 2014. 9 years have passed since then, but only a few municipalities have analyzed and understood the progress of public facilities development from its formulation to the present. Additionally, the fixed asset ledger, which contains accounting information from construction to disposal of public facilities, is expected to be utilized for facility management. Therefore, this report proposes a method to grasp the progress of public facilities development using the fixed asset ledger.</p>

<p>1.Introduction</p><p>Aging of public facilities, declining population and increasing local government finance have been questioned conventionally. From such as situation, In April 2014, the Ministry of Internal Affairs and Communications requested municipalities to formulate a "Comprehensive Management Plan of Public Facilities and Infrastructures". In the plan, the facility reduction target and basic policy are described using uniform calculation of renewal and renovation expenses. However, the construction transition of public facilities differs from municipality to municipality, and the uniform calculation does not provide an appropriate analysis.</p><p> </p><p>2.Purpose of This Study</p><p>The purpose of this study is to consider public facilities improvement policies according to the differences of construction transition.</p><p> </p><p>3.Research Method</p><p>The method is classifying in the transition patterns of target municipalities by cluster analysis. Then, we estimate renewal and renovation expenses and reveal features and problems by each cluster.</p><p> </p><p>4.Research Result</p><p>The results of this study are summarised below.</p><p>1) By constructing the database of public facilities, it becomes possible to compare between municipalities.</p><p>2) The construction transitions of public facilities are classified into 4 types. These types are Economic growth period peak type, Early peak type, Two peaks type and Continuous construction type.</p><p>3) The transitions of renewal and renovation expenses are different for each type, and improvement policies such as reduction and leveling are also differ from type to type.</p><p>・ Municipalities that constructed public facilities in particular from 1950 to 1970 need to reduce public facilities quickly because it is difficult to level out renewal and renovation expenses due to early renewal period and many facilities that have not been renovated.</p><p>・ Municipalities that built intensively public facilities around 1980 have to level out expenses by renovating the facilities that have not been renovated and accelerating renewal time during the period up to about 2060. It is effective in reducing school facilities, government office, parenting support facilities and public housing built around 1980.</p><p>・ For municipalities that have continued to construct public facilities since 1990, it is desirable to consider renewal and renovation together and level out the expenses including the next about 40 years. They need to investigate surplus public facilities except school facilities and plan for reduction in those facilities.</p>
