Improving the farmer'agricultural income is a systematic project.Tthis paper establishes a theoretical analysis model and applies the VAR to analyse the response of farmer'agricultural income to rural investment and agricultural land use efficiency.The results show: the influence factors including CRSTE,VRSTE,SCALE of agricultural land,the rural investmen level have a long stable and positive impact on farmer'agricultural income.The contribution to the growth of farmers' income of agricultural land use efficiency' CRSTE is much higher than the rural investment.Consequently,in the long term,although improving the level of rural investment and CRSTE,VRSTE,SCALE have a positive impact on the the growth of farmer'agricultural income,the growth of farmers' income is much depending on the agricultural land SCALE.In the short term,increaseing the level of rual investment will be helpful to improve farmer'agricultural income,and improving the VRSTE can make farmer'agricultural income reduce after the first growth.In the range of decreasing SCALE' returns,the impoving of SCALE can also increase farmer'agricultural income.
