This study will identify the problems in Gastrodia cultivation in Korea and China by taking the farmers in the main production area of Muju, Korea, and farmers in Yichang, China, where the conditions are similar to those in Muju, as the objects of the research, and then propose effective improvement strategies accordingly. In this process, a survey was conducted to analyze the income and costs of farmers, and the DEA analysis was applied to make a comparative analysis of the operational efficiency. The results of the analysis showed that, firstly, the average efficiency of all survey respondents was 94.1%, and the ineffectiveness was 5.9%. And eleven efficient farms in Korea and nine in China were derived by the BCC model. Secondly, the results of the comparative analysis of Korean and Chinese farmers' operations per 10a showed that the average input costs of Korean farmers accounted for 41.2% of the gross margin, while the average input costs of Chinese farmers accounted for 29.1% of the gross margin, indicating that Korean farmers’ operations are much less efficient than those in China. Thirdly, it can be seen that there is a clear difference in the cultivation technology between Korea and China, with Korea producing 12.1 kg per ping compared to 58.8 kg in China, and Grastrodia production in China is 4.9 times higher than that of Korea. In the future, it will be necessary for Korea to switch cultivation methods, as China has done, and steadily raise productivity by adjusting the input factors of Grastrodia seed and seed culture that directly affect the yield of Grastrodia.
