Factors Affecting Technical Efficiency of Rice Farmers in Village Reservoir Irrigation Systems of Sri Lanka
研究了斯里兰卡村庄水库灌溉系统中稻农技术效率的影响因素，发现农民组织成员身份和集体行动参与率是提高效率的关键。
Abstract Given the importance of water for rice production, this study examines the factors affecting the technical efficiency (TE) of irrigated rice farmers in village irrigation systems (VIS) in Sri Lanka. Primary data were collected from 460 rice farmers in the Kurunagala District, Sri Lanka, to estimate a stochastic translog production frontier for rice production. The mean TE of rice farming in village irrigation was found to be 0.72, although 63% of rice farmers exceeded this average. The most influential factors of TE are membership of Farmer Organisations (FOs) and the participatory rate in collective actions organised by FOs. The results suggest that enhancement of co‐operative arrangements of farmers by strengthening the membership of FOs is considered important for increasing TE in rice farming in VIS.
