We use relevant economic and labor force data from 1990 to 2009 of Henan Province to analyze the dynamic relation between stock of rural human capital and farmers’ income.Results indicate that a certain causal relationship and long-run equilibrium relation exist between rural human capital and farmers’ income,but their interaction shows some lagging characteristic.Increase of farmers’ income in Henan Province increases the stock of rural human capital in this province for a short term.However,in the long run,this accumulation effect will decline along with renewal and aging of knowledge.The positive promotion action of rural human capital on farmers’ income will appear after a long lag time.Therefore,the policy of strengthening rural human capital input should be long-term and continuous.
