摘要|Abstract

Expanding electricity access has profound effects on economic behavior in developing countries. Small hydropower (SHP), as a clean, decentralized, and flexible energy source, played a crucial role in the early stages of China's rural electrification. This paper evaluates the impacts of rural electrification policies on SHP development and subsequent changes in household consumption and agricultural production, leveraging data from over 1,500 counties across China. Using a difference-in-differences (DID) framework, we examine the effects of three waves of the Rural Primary Electrification Program implemented between 1980 and 2000. We find that counties subject to electrification reforms experienced a 25% increase in total installed SHP capacity compared to non-reform counties. Using these policy-induced variations as an instrumental variable for SHP expansion, we further explore its consequent effects. On the consumption side, increased SHP capacity significantly boosted household ownership of electric appliances, such as washing machines, refrigerator, and televisions, with heterogeneous effects across income groups. On the production side, enhanced electricity access increased the total power of agricultural machinery, expanded grain acreage, and raised crop output. Heterogeneity analysis further reveals that improved electricity access particularly promoted the cultivation of high-water-demand crops, such as rice, by facilitating greater agricultural labor input and mechanization. Overall, the findings highlight the broader economic transformations induced by rural electrification beyond mere access to electricity, underscoring the importance of clean decentralized energy in promoting rural development.
