The Impact of Park Green Space Areas on Urban Vitality: A Case Study of 35 Large and Medium-Sized Cities in China

Urban park green spaces not only significantly enhance urban environmental quality, but also increase social interactions, making them a crucial factor in urban vitality, particularly in densely populated and ecologically stressed metropolitan areas. This study utilizes panel data from 35 major cities in China from 2012 to 2022 to analyze the impact of per capita urban park green space areas on urban vitality. The results confirm the significant effect of per capita park green space areas on urban vitality. However, this impact diminishes under the single-threshold conditions of GDP and total park green space areas, as well as the double-threshold condition of total population. Based on these findings, the study proposes policy recommendations emphasizing the importance of park green space construction to promote sustainable urban development and improve residents’ quality of life.
