报告内容
This paper investigates the effect of agricultural technology on rural welfare by analyzing China’s first adoption of electric irrigation. In 1924, rural areas of Wujin county in Jiangsu province unexpectedly gained access to electric irrigation from a nearby urban power plant. Based on county-level panel data from 1912 to 1933, difference-in-differences analysis and the synthetic control method show positive effects on farmland values but not on farm wages. Further analysis using newly published household-by-crop-level data illustrates that access to electric irrigation increased crop yields and the irrigated area for rice, the most water-sensitive crop, and reduced agricultural labor inputs. Heterogeneous analysis on farm size shows that, while electric irrigation increased farmland values for all farms, it led to divergent changes in labor input for small and big farms.
