Roads and Cropland: Infrastructure Expansion and Cropland Conversion in Rural China 1: Renmin University of China, China, People's Republic of; 2: University of Maryland Infrastructure-led development and agricultural land preservation represent competing priorities in rapidly developing countries. This study examines the causal impact of rural road construction on land use changes in China from 1995 to 2020, using a comprehensive village-level panel dataset covering 381,153 villages. Employing a matching-based instrumental variable strategy that exploits hierarchical transportation planning, we find that each kilometer of road expansion causes a loss of 4.14 hectares of cropland and a gain of 4.33 hectares of construction land. Structural decomposition reveals that 91.2% of cropland outflow converts to construction land, while compensatory inflows remain limited, creating a six-fold imbalance between outflow and inflow. Policy intensification in 2010 reduced road-induced conversion by 40%, demonstrating that regulations can dampen land use pressures. However, the dominant conversion pathway persists, and compensatory mechanisms face implementation challenges. The findings highlight the need for complementary policy instruments that align economic incentives with preservation goals. | |
