Green revolution and labour demand in rice farming: The case of central Luzon, 1966–90
利用1966-1990年中吕宋农户调查数据，研究现代水稻品种对劳动力需求的影响，发现其显著增加劳动力需求，并未引发广泛采用节省劳动力的技术。
While the adoption of modern rice varieties (MVs) increased labour requirements for crop care and other activities, it might have induced the adoption of labour‐saving technologies. Thus, whether the net impact of MV adoption on labour demand is significantly positive is still debated in the green revolution literature. Using farm‐level survey data collected in Central Luzon from 1966 to 1990, this study estimated simultaneously the labour‐saving technology adoption and the labour demand functions. We found, among other things, that MVs increased labour demand significantly without inducing the widespread adoption of labour‐saving technologies.
