摘　　要：基于1624份实地调研微观样本数据,系统地检验并分析了农地确权对农村家庭收入的影响及其作用机制。通过工具变量估计结果显示:实施土地确权并没有提高农村居民家庭总收入水平,反而在一定程度上具有显著的抑制作用。这表明“农地确权—农户增收”悖论现象的存在,具体作用机制为农地确权作为产权禀赋可显著提高农村家庭农业收入,但作为制度约束,农地确权却形成了农户的机会成本,显著降低了其非农收入。前者增加无法弥补后者损失,因此总收入下降。进行适度规模经营,并提高农民非农收入才是实现其增收的有效保障。Based on 1624 micro sample data of field investigation,this paper examines the impact of praedial right confirming on rural household income and its mechanism of action.Through instrumental variable estimation,the results show that praedial right confirming does not improve the total income of the rural households in the short term,but has a certain inhibitory effect on it.This suggests the existence of paradox phenomenon about praedial right confirming and farmers'income increasing.The mechanism of the paradox is that praedial right confirming,as property rights endowment,can distinctly improve rural household agricultural income,but as system restraint,significantly decrease non-farm income because of opportunity costs.The former increase can not make up for the latter loss,so the total income decline.Carrying out moderate scale management and raising farmers'non-agricultural income is an effective guarantee to realize their income increase.
