日本語
クリーンテクノロジー（CT）導入を、異種行動（合理的、群集、慣性）の集団ゲームとしてモデル化。CT採用には価格優位性か、社会啓発による群集効果が必要で、環境被害認識だけでは不十分であることを示す。
English
This paper models clean technology adoption as a multi-type mean-field game with rational, herding, and lethargic agents. It finds that widespread adoption requires either a small price disadvantage or a large herding population influenced by social awareness, while environmental damages alone provide insufficient incentives.

📝 gxceed 編集解説 — Why this matters
日本のGX文脈において
日本のGX政策では、補助金や排出量取引などの価格メカニズムに加え、社会的な同調効果を活用した普及策（例：地域コミュニティでの導入促進）の重要性を示唆する。
In the global GX context
Globally, the paper challenges the assumption that highlighting environmental harm drives adoption, emphasizing the need for price incentives and social influence mechanisms—relevant for designing effective climate policies.
👥 読者別の含意
🔬研究者:Provides a novel game-theoretic framework for studying technology adoption with behavioral heterogeneity and identifies conditions for equilibrium.
🏢実務担当者:Suggests that corporate sustainability campaigns should leverage social norms and herding behavior rather than solely environmental messaging.
🏛政策担当者:Advises that carbon pricing or subsidies are more effective than awareness campaigns on environmental damage alone.
📄 Abstract（原文）
The adoption of clean technologies (CTs) plays an important role in reducing carbon dioxide (CO$_2$) emissions. We study CT adoption in a large population of consumers with heterogeneous behavioral tendencies. We model the interaction among the agents as a multi-type mean-field game in which the agents choose between clean and polluting technology based products and may either behave as rationals (trading off price and moral incentives), herding agents (just follow the majority), or lethargic agents exhibiting inertia toward adopting the new technologies. We characterize equilibrium CT adoption levels using the recently introduced notion of $\boldsymbol{\alpha}$-Rational Nash Equilibrium ($\boldsymbol{\alpha}$-RNE) and its multi-type extension. We then identify a stable subset using the limits of a stochastic turn-by-turn behavioral dynamics. Our results highlight the role of population composition in determining CT adoption. In particular, widespread adoption requires either a sufficiently small price disadvantage for CTs or the presence of a sufficiently large herding population that can be influenced through social awareness programs. Surprisingly, we could prove that environmental damages do not provide sufficient incentives to increase CT adoption.
