本論文は、中国の低炭素都市（LCC）政策を自然実験として、企業の排出削減対応の異質性を分析。産業部門（第二次産業）は選択的に電力消費（Scope 2）を削減する一方、石炭・石油（Scope 1）は維持し、総排出量は減少しない。サービス部門（第三次産業）は包括的に全エネルギー源を削減し、系統脱炭素と同期する。セクター固有の生産硬直性に応じた政策（サービス部門：系統同期、産業部門：移行金融）の必要性を示唆。
English
This study uses China's Low-Carbon City policy as a quasi-natural experiment to analyze firm-level emission reduction responses. Industrial firms selectively reduce electricity consumption (Scope 2) while maintaining Scope 1 fossil fuel use, resulting in no total emission reduction. Service firms achieve comprehensive reductions across all energy types and synchronize with grid decarbonization. Findings suggest differentiated policies: grid synchronicity for services, transition finance for industry.

📄 Abstract（原文）
China’s Low‐Carbon City (LCC) policy provides a quasi‐natural experiment to evaluate the micro‐level efficacy of macro‐level climate regulations. Using a dataset of 2.45 million firm‐year observations spanning 2007 to 2016, this study investigates the heterogeneous emission reduction responses of firms to city‐level environmental shocks. The empirical analysis reveals a structural divergence in corporate compliance strategies driven by differences in factor substitution elasticity. Industrial firms (secondary sector) exhibit a selective emission reduction pattern: they maintain production scale by reducing auxiliary electricity consumption (Scope 2), while their core reliance on coal and oil (Scope 1) remains heavily locked in. Consequently, their total emissions are largely unresponsive to external grid decarbonization, reflecting low grid coupling due to process inertia. Service-sector firms (tertiary sector), in contrast, adopt a comprehensive emission reduction approach. Leveraging higher operational flexibility, they achieve absolute reductions across all energy types through structural adjustments and scale contraction. Their emission performance is intimately synchronized with upstream grid decarbonization, demonstrating high supply-demand synchronicity. These findings suggest that sector-specific production rigidities necessitate differentiated regulatory approaches. For service-oriented economies, policies should prioritize supply-demand synchronicity between grid decarbonization and downstream electrification; for heavy-industrial sectors, targeted transition finance is needed to break entrenched fossil-fuel lock-in.
