In order to further enhance the anti-risk ability of ginger industry and increase rural household income,on the basis of studying China's ginger planting input-output,this paper conducted comparative analysis on different scale of operation,different age of farmers,and planting cost and benefit.At the same time,the paper also analyzed the factors affecting the cost and income fluctuation of ginger planting.The results showed that the ginger price fluctuation was one of the most important factors causing the instability of income.Besides,the instability of ginger yield also had greater impact on profits.The scale efficiency of ginger was not significant.Labor cost rose sharply along with the increase in scale,leading to a drop in profits.Judging from the cost point of view,the older farmers adopted management strategy of reducing investment and mitigating risk,which had become an obstacle to the high-quality development of ginger.On account of these,the paper suggested to develop ginger featured insurance,reducing management risk of farmer household;developing futures market,stabilizing ginger price;increasing investment in research and development of small machinery for ginger;and to improve the scale efficiency of ginger industry through service scale.
