中文摘要：
本文采用多部门模型分析改良陆稻技术采用对收入在技术采用户和非采用户间分配的影响，并利用滇西南山区农户调查数据对分析的推论进行了验证。结果表明，当农户的生产组合整体从陆稻生产向非陆稻生产方向调整时，采用了改良陆稻技术的农户生产组合调整的幅度小于非采用农户调整的幅度，来自陆稻的收入进一步集中于技术采用户；由于技术的“溢出效应”，来自非陆稻的收入也向技术采用户集中；新技术的采用促进了技术采用户收入水平的整体提高。
英文摘要：
The paper applies a multi -sector model to analyze the impact of improved upland rice technology on income distribution between technology adopting farmers and non - adopting farmers and uses household survey data from southwestern Yunnan to test the inference drawn from the model. The result shows, when farmers adjust their production from upland rice production to non - upland rice production, the adopting farmers make less extent adjustment than non - a- dopting farmers. The income from upland rice becomes increasingly concentrated in the adopting farmers. At the same time, income from non - upland rice is also concentrated in the adopting farmers for the technology＇ s spillover effect. The technology increases the income of adopting farmers.
