中国の村落合併・再定住（VMR）政策が炭素排出と炭素吸収に与えた影響を、準自然実験として差分の差法で分析。VMRは人口集中やインフラ共同化により排出を削減し、土地集約化や植生改善で吸収源を強化することを実証。地域特性に応じた効果の差異も示した。
English
Using a difference-in-differences approach, this study evaluates the impact of China's Village Merger and Resettlement (VMR) policy on carbon emissions and carbon sinks. It finds that VMR reduces emissions through population concentration and centralized infrastructure, while enhancing sinks via land intensification and improved vegetation cover. Heterogeneity analysis shows stronger effects in areas with higher income gaps and urbanization rates for emissions, and in rugged terrains for sinks.

📄 Abstract（原文）
Land-use change is a major driver of climate change and carbon-cycle imbalance, yet its dual effects on carbon emissions and carbon sinks remain insufficiently examined in the context of rural spatial restructuring. As a key form of county-level rural land-use transformation in China, the Village Merger and Resettlement (VMR) policy reshapes the spatial distribution of rural population and land by concentrating residents, vacating idle homesteads, and optimizing land allocation. Treating VMR as a quasi-natural experiment, this study uses county-level panel data and a difference-in-differences approach to evaluate its impacts on regional carbon emissions and carbon-sink capacity. The findings indicate that VMR significantly reduces regional carbon emissions while enhancing carbon-sink capacity. Mechanism analysis shows that the emission-reduction effect operates mainly through population concentration, centralized infrastructure provision, and reduced household energy consumption, whereas the carbon-sink effect is driven by land intensification, agricultural mechanization, cultivated land-use adjustment, and improved vegetation cover. Heterogeneity analysis further reveals stronger emission-reduction effects in areas with a larger pre-policy urban–rural income gap and higher urbanization rates, and stronger carbon-sink effects in areas with greater terrain fragmentation and higher elevations. These findings suggest that rural spatial restructuring can contribute to regional carbon governance.
