論文概要:Urban development plays a pivotal role in shaping economic growth, societal structures, and environmental sustainability. This study conducts a comprehensive assessment of urban development and its environmental implications by comparing cities in China and Japan, which are at different stages of urbanization and face distinct challenges. While China grapples with rapid urbanization and its associated environmental pressures, Japan contends with urban shrinkage due to demographic shifts and economic restructuring.

The research adopts a spatial analysis approach, integrating Geographic Information Systems (GIS) and remote sensing (RS) technologies, alongside spatial econometric models such as the Semiparametric Geographically Weighted Regression (SGWR). These methods reveal spatial dependencies and heterogeneities in urbanization and environmental impacts, offering deeper insights into the driving factors of urban growth and shrinkage. Case studies on China’s Beijing city cluster and Japan’s Kitakyushu provide granular analyses of urbanization trends, environmental challenges, and mitigation strategies, including the effects of compact city planning and urban heat island (UHI) phenomena.

The findings highlight that while urbanization drives economic and infrastructural growth, it often exacerbates environmental issues such as heat islands, resource consumption, and pollution. Conversely, urban shrinkage, characterized by population decline and inefficient land use, demands innovative urban regeneration strategies. This study underscores the need for tailored policy responses to address the specific challenges of urbanization and shrinkage, leveraging spatial tools to inform sustainable urban planning and environmental management.

By bridging urban development and environmental considerations across varying contexts, this research contributes to the discourse on achieving sustainable and resilient cities. It provides valuable insights for policymakers and urban planners to balance economic, social, and environmental goals in shaping the future of urban landscapes.
