本論文は、グリーン経済への移行を技術や政策だけでなく、個人の行動と社会規範に基づく変革として捉える統合的分析枠組みを提示する。「十分性エージェント」モデルを提案し、低炭素素材、行動インセンティブ、十分性教育の3つの柱からなる完全解決チェーンを構築。エージェントベースの拡散モデルを用いたモンテカルロシミュレーションにより、経済的インセンティブだけでは大量普及は限定的だが、社会規範とアクセシビリティを統合したポリシーミックスが高い導入率と炭素削減をもたらすことを示した。

English

This paper presents an integrative framework for green economy transition focusing on individual behavior and social norms, not just technology and policy. It proposes a 'Sufficient Agent' model and a three-pillar solution chain: low-carbon materials, economic incentives, and sufficiency education. Using an agent-based diffusion model with Monte Carlo simulations, it shows that combining economic incentives with social norms and accessibility yields higher adoption and carbon reduction than incentives alone.

📝 gxceed 編集解説 — Why this matters

日本のGX文脈において

日本ではGX実現に向けた行動変容政策(ナッジ等)が注目されている。本論文の「十分性エージェント」モデルは、経済的インセンティブに加えて社会規範と教育の重要性を定量的に示しており、日本の建設部門の脱炭素や国民運動に示唆を与える。

In the global GX context

This paper contributes to the behavioral economics of sustainability transitions, offering a micro-founded model applicable globally. It aligns with the growing emphasis on demand-side solutions in climate policy, as seen in IPCC reports and ISSB's consideration of social factors.

👥 読者別の含意

🔬研究者:Provides a quantitative framework for modeling behavior-driven diffusion of green technologies and practices, useful for further empirical or simulation studies.

🏢実務担当者:Offers insights for designing corporate sustainability programs that combine financial incentives with social norm building and education to boost adoption.

🏛政策担当者:Demonstrates the need for policy mixes that integrate economic instruments with social and educational measures to achieve mass diffusion and carbon reduction.

📄 Abstract(原文)

This article presents an integrative analytical framework that interprets the transition to a green economy not merely as a matter of technological modernization and macro-policy, but as a behaviororiented transformation shaped by social norms and individual decision-making mechanisms.The aim of the study is to theoretically and quantitatively substantiate how the individual decision-maker, the "Sufficient Agent" (Homo Sufficiens), rationalizes resource use based on the logic of sufficiency.The paper proposes a three-pillar "complete solution chain": 1) low embodied carbon and circular construction materials (earth/straw blocks, clay plasters, low-processing-energy coatings) supported by performance-based carbon standards (EC_building limit and differential sub-limit for non-structural elements in high-rise buildings), 2) behavior-oriented economic incentive mechanisms (bonuses, tariff signals) and 3) norm formation through "Sufficiency Education".To evaluate the systemic impact of this framework, a simplified agent-based diffusion model with a logit decision function was constructed, combining economic attractiveness (NPV), social impact (SI) and technological accessibility (TA).Monte Carlo simulations over a 10-year horizon yielded interval results.Findings show that while economic incentives alone accelerate early adoption, mass diffusion remains limited without integration of social norms and accessibility; in "policy mix" scenarios, however, adoption rates and carbon reduction systematically follow a higher trajectory.The article demonstrates that the main driver of the green transition is not technology alone, but the transformation of the social system, thereby providing micro-macro justification for behavior-oriented policy design.
