摘　　要：本文基于2000～2014年中国31个省域面板数据,综合运用固定效应模型与门限回归模型,检验农业科研投资的减贫效应。实证结果表明：区域市场化水平直接影响科研减贫效果并存在两个明显的门限值。市场化水平较低时,农业科研投资的减贫效应微弱;当市场化水平跨越一定门限,农业科研减贫的作用显著提高;但处于最高市场化水平的省份,其科研减贫效应却反常地低于中等市场化水平的省份。因此,建议政府根据市场化水平的不同采取差异化政策,促进科研减贫效应的充分发挥。Based on China＇s 31 provincial panel data from 2000 to 2014, this paper uses the fixed effects model and the threshold regression model, to examine the effects of agricultural research investment to reduce rural poverty. The empirical results show that regional marketization level directly influences the poverty reduction effect and there are two obvious threshold value. In the low level of marketization of the provinces, poverty reduction effect of agricultural research investment is not enough; as the marketization level across a certain threshold, the effect of poverty reduction increased significantly; but in the highest marketization level of province, it is abnormal under moderate marketization level province. Therefore, the government should adopt the policy of differentiation of marketization level, promote the poverty reduction effect into full play.
