本研究は中国の低炭素都市パイロット政策が家計の炭素排出に与える因果効果を、差分の差分法を用いて推定した。その結果、政策は家計消費水準の低下を通じて排出を有意に削減し、高所得・既婚・非高齢世帯で効果が大きいことが分かった。間接排出や住宅関連排出は減少する一方、電力消費に伴う排出は増加した。
English
This study uses a staggered difference-in-differences model with Chinese household panel data to estimate the causal effect of low-carbon city pilot policy on household carbon emissions. It finds a significant reduction driven by decreased consumption levels rather than emission intensity improvements, with heterogeneous effects across income, marital status, and age. The policy reduces indirect, housing-related, and home maintenance emissions but increases electricity-related emissions.

日本のGX文脈において
日本でも地域脱炭素やゼロカーボンシティの取り組みが進む中、中国の低炭素都市パイロットの家計排出削減効果を実証した本知見は、日本の自治体政策の設計や評価に示唆を与える。特に、消費抑制を介した排出削減メカニズムは、日本の消費行動の違いを考慮した政策転用の参考となる。
In the global GX context
As cities worldwide launch climate action plans, this study provides causal evidence from China that low-carbon city pilots effectively reduce household carbon emissions through consumption reduction. It adds to the global literature on demand-side climate policy, offering insights for policymakers designing urban decarbonization strategies and highlighting potential trade-offs such as increased electricity emissions.
👥 読者別の含意
🔬研究者:Provides a rigorous causal identification of household-level emission reductions from a demand-side policy, useful for researchers studying urban climate policy evaluation and consumption-based emissions.
🏢実務担当者:Local government officials and urban planners can learn from China's low-carbon city pilot design and its heterogeneous effects to tailor similar programs in their own cities.
🏛政策担当者:Offers evidence that demand-side policies can reduce household emissions, suggesting that combining consumption-oriented measures with supply-side decarbonization may accelerate climate goals.
📄 Abstract（原文）
As a major source of carbon emissions， household consumption is a key domain for demand-side carbon mitigation. Using data from four waves of the China Family Panel Studies， this study employs a staggered difference-in-differences model to identify the causal effect of the low-carbon city pilot on household carbon emissions. It further explores the underlying mechanisms and conducts heterogeneity analyses based on household characteristics. In addition， it comprehensively assesses the impact of the low-carbon city pilot on household carbon emissions across different consumption categories and specific items. The results indicate that the low-carbon city pilot significantly reduced household carbon emissions， and this conclusion remained robust to a series of checks， including sample selection， alternative measurements of key variables， and placebo tests. The reduction in household carbon emissions was driven primarily by a decline in household consumption levels rather than by improvements in carbon emission intensity. The negative effect was more pronounced among high-income households， married households， and non-elderly households， while the difference between urban and rural households was insignificant. Moreover， the low-carbon city pilot reduced indirect emissions， housing-related emissions， and emissions from home maintenance but increased emissions from electricity use. These findings provide household-level policy implications for achieving the dual-carbon goals， addressing climate challenges， and promoting a comprehensive green transition in socio-economic development.
