Abstract: Based on the national cucumber planting cost-benefit data from 2011 to 2020,a comparative analysis was conducted on the changes in cost-benefit, sensitivity of influencing factors, and contribution rates of outdoor cucumber and facility cucumber planting.The results showed that the net income changes of facility cucumber and open field cucumber were the most sensitive to yield and price,respectively.The order of arrangement in facility cucumber was labor cost,land cost,and material and service cost,while the order of arrangement in open field cucumber was labor cost,material and service cost,and land cost.By measuring the contribution rates of various influencing factors to facility cucumber and open field cucumber cultivation,it was found that labor cost and prices each had the greatest contribution rates to the changes in income from facility cucumber and open field cucumber cultivation in China,while material and service cost and land cost had relatively limited contributions to the changes in income from facility cucumber and open field cucumber cultivation in China.
