本研究は青島市の172の地下鉄駅周辺を対象に、公共サービス施設の配置タイプを4つに分類し、住民の移動による炭素排出量との関連を分析した。バランス型配置が最も排出量が低く、施設密度・アクセシビリティの向上が排出削減に寄与することを示した。さらに、3つの低炭素更新戦略を提案し、施設増加による排出削減効果をシミュレーションで検証した。
English
This study classifies public service facility layouts in TOD blocks around 172 metro stations in Qingdao into four types and analyzes their association with residents' travel carbon emissions. The balanced type shows the lowest emissions, and higher facility density and accessibility are linked to lower emissions. Three low-carbon renewal strategies are proposed, with simulations showing that a 20% increase in facilities could reduce weekly carbon emissions by 28-33% in selected areas.

📝 gxceed 編集解説 — Why this matters
日本のGX文脈において
日本のコンパクトシティ政策や立地適正化計画において、公共交通沿線の施設配置と低炭素化の関連を示す実証データとして参考になる。特に、SSBJ開示や自治体の温暖化対策計画策定において、都市構造と排出量の関係を定量化する手法が有用。
In the global GX context
This study provides empirical evidence on how urban form and facility layout affect travel emissions, relevant to global efforts on sustainable urban development and climate mitigation. It offers a methodology for assessing the carbon impact of land-use planning, which can inform urban policies aligned with climate goals such as the Paris Agreement.

📄 Abstract（原文）
The spatial organization of public service facilities within transit-oriented development TOD blocks is closely related to residents’ daily travel conditions and travel-related carbon emissions. This study examined all 172 operating metro station areas in Qingdao using public service facility POIs, buildings, pedestrian road network and population data, field observations, and a resident travel survey. K-means clustering, spatial syntax analysis, Global Moran’s I, spatial regression, FDR-adjusted Pearson correlation analysis, and scenario simulation were jointly applied. Four facility layout types were identified: Spatially Balanced Type, Main-Road-Concentrated Type, Point-Concentrated Type, and Scattered-and-Disordered Type. The survey included 240 valid respondents distributed across all 41 station areas along Qingdao Metro Line 1. The Spatially Balanced Type had the lowest mean weekly per capita travel carbon emissions, followed by the Main-Road-Concentrated Type, whereas the Point-Concentrated and Scattered-and-Disordered types had similarly higher emission levels. The density and accessibility of Commercial and Entertainment facilities, Medical and Health facilities, and total facilities remained negatively associated with travel carbon emissions after FDR correction. Spatial syntax analysis showed that higher road network integration and connectivity were associated with stronger facility agglomeration. Facility density, road density, and population density exhibited significant positive network-based spatial autocorrelation, and the spatial error model provided the best fit, identifying positive associations of facility density with road density and population density. Based on these findings and field observations, three differentiated renewal pathways—node embedding, proximity coordination, and intensive integration—were proposed. Under the specified scenario, a 20% increase in facilities was associated with modeled reductions in aggregate weekly carbon emissions of 32.3% in Li Village, 28.1% in the University of Petroleum station area, and 33.0% in Jinggangshan Road. These results suggest that improving overall facility coverage may support lower-carbon travel across different facility layout contexts. This study connects facility layout typology, spatial structure, travel carbon emission associations, and differentiated renewal strategies at the TOD-block scale.
