EFFECT AND MECHANISM OF CONSERVATION TILLAGE TECHNOLOGY ON INCREASING FARMERS'INCOME
It is of great theoretical value and practical significance for promoting the high-quality development of conservation tillage and transformation of agricultural development mode in China to explore the influencing mechanism of conservation tillage technology on farmers'income.Based on the survey data of grain growers,the effects of conservation tillage on farmers'income and their differences were investigated with the variable method,quantile regression,and endogenous treatment effect model,and the mechanism of income increase effect was further explained.This study showed that conservation tillage technology had a great effect on increasing farmers'income,but this effect was different among different income groups.The low-and middle-income farmers had benefited more from the adoption of conservation tillage technology than the middle-and high-income farmers,which was characterized by benefiting the poor.In addition,the adoption of conservation tillage technology mainly promoted farmers'income by increasing grain output,and there was no mechanism to improve farmers'income by promoting non-agricultural employment.These findings suggest improving the agricultural machinery operation service of conservation tillage to support low-income farmers,as well as aiming at the subsidies and investment of conservation tillage technology and improving the conservation tillage technology route applicable to local agricultural production.
