Outline of Final Research Achievements

The park management (PM) that evolved from the park-renewal project based on Installation-Management Permission (IMP) in Tennoji Park, a major urban park in Osaka City, Japan is evaluated herein. The PM results and financial effects of the introduction of IMP in "TEN-SHIBA", entrance area of Tennoji Park are evaluated based on both the characteristics of park users obtained by a questionnaire as well as an observation survey of the park users, and a data analysis of the track record. Based on a comparison with Sumiyoshi Park, an urban park similar to "TEN-SHIBA" but without the introduction of IMP, it was found that young females were the predominant users of "TEN-SHIBA", and the average staying time on the lawn plaza was 2 minutes longer than that in Sumiyoshi park. These results suggest that IMP might be an effective method for the revitalization of existing urban park.

Academic Significance and Societal Importance of the Research Achievements

本研究は、近年の少子高齢化、地方財政の困難に直面する中、新たな都市公園の在り方を模索するために、民間活力を取り入れた新たな設置管理許可制度に基づいて天王寺公園の中央に新たに整備された芝生広場である天王寺公園エントランスエリア「てんしば」に着目し、その評価を主軸に置きつつ、既存の指定管理制度のもとで運営されている都市公園である住吉公園との比較を行うことにより、民間活力に基づいた都市公園再生手法による都市公園への回遊性向上や、財政的な持続性に対する効果を確認することができた。以上の結果から、新たな公園再生手法としての設置管理許可制度の有効性が確認されたといえる。
