中国农户农业投资的低水平饱和现象及其成因

基于农户农业投资与农民收入呈“倒U型”关系、与农业经营效益呈负相关关系这两个反常现象，认为我国农户农业投资存在低水平饱和的问题。收入水平较高时农业投资的下降趋势，是由非农收入的负贡献引起的；农户农业投资水平与农业经营效益呈现负相关，则是由非农经营效益较高、农业生产中资本的低水平过密化及各地区间条件存在差异等因素导致。

The Low-level Saturation Phenomenon in Chinese Peasant Household's Agricultural Investment and Its Causes

Based on two abnormal phenomena which are the peasant household＇ s agricultural investment＇ s ＂upset U shape＂ relationship with the income level of peasants and negative correlativity with the profit margin of agricultural management, this paper holds that there is low - level saturation problem in Chinese peasant household＇ s agricultural investment. The declining trend of the agricultural investment in high-income period is thought to be caused by the negative contribution of non-agricultural income. And the negative correlativity between the peasant household＇ s agricultural investment and profit margin of agricultural management is thought to be caused by the higher profit margin of non-agriculture manage- ment, the ＂involution＂ of capital in agricultural production and the different conditions in every region. Finally, some policy advices are put forward accordingly.
