本研究はEU諸国の建設部門における廃棄物発生のマクロ経済的要因を分析した。生産性向上、グリーン投資、循環型材料活用は廃棄物削減に寄与する一方、都市化と人口密度は廃棄物を増加させることを発見。環境税や気候変動対策投資も効果的だが、両者が高い場合は相乗効果が減少する。
English
This study examines macro-level drivers of construction waste generation using panel econometric models for EU countries. It finds that higher productivity, green investment, and circular material use reduce waste, while urbanization and population density increase waste. Environmental taxes and climate mitigation investments also reduce waste, but their combined effect diminishes when both are high.

📝 gxceed 編集解説 — Why this matters
日本のGX文脈において
日本でも建設廃棄物は重要な環境課題であり、本研究成果（生産性向上やグリーン投資による削減効果）は日本の建設業界の廃棄物対策に示唆を与える。ただし、日本の規制や社会的背景を考慮した追加分析が必要。
In the global GX context
This paper adds to the global literature on sustainable construction by empirically identifying key drivers of waste generation across EU countries. Its findings on the roles of productivity, green investment, and environmental taxes are relevant for policymakers designing circular economy strategies and waste reduction targets.
👥 読者別の含意
🔬研究者:Useful for scholars studying waste management drivers and applying panel econometric methods to environmental sustainability.
🏢実務担当者:Construction firms can leverage the insight that green investments and productivity improvements reduce waste generation.
🏛政策担当者:Highlights that environmental taxes and climate mitigation investments can be effective, but coordination is needed to avoid diminishing returns.
📄 Abstract（原文）
Purpose This study examines macro-level factors influencing construction waste generation, focusing on economic, regulatory, social, and environmental aspects. This research aims to identify and analyse the macroeconomic factors that influence waste generation in the construction sector. Design/methodology/approach Panel econometric models are applied to explore (nonlinear) relationships between waste generation intensity and explanatory variables in the construction sector of the European Union countries. Total waste-to-value-added and total waste per capita are used as the dependent variables. The factors selected for the research as independent variables include productivity in the construction sector, investments in climate change mitigation within the construction sector, environmental taxes paid by construction sector companies, circularity, and contextual indicators that describe socioeconomic development at the country level. Findings Using four variations of econometric specification, it is found that higher productivity, green investment, and circular use of materials reduce waste, while urbanisation and population density increase waste. Investment in climate change mitigation and environmental taxes also contributes to waste reduction, but their combined effect is reduced when both are high. Wealthier countries tend to produce more waste; however, the more complex relationship, exhibiting U- and N-shaped patterns at different stages of development, was not robustly detected. Originality/value The relevance of this topic is underscored by the growing global emphasis on sustainable development, as the construction industry is a major contributor to environmental degradation. Understanding the key drivers of construction waste generation is critical for developing effective policies to reduce waste and improve resource efficiency. The findings highlight the importance of productivity, green investment, and circular materials in reducing waste, while urbanisation and population density pose challenges. This study informs policy strategies for sustainable construction and waste management, particularly in countries with fast-developing construction sectors.
