This study aimed to analyze the status of the economic linkage between farm households and Orion Vina Food Co., Ltd. enterprise in potato production and selling in Dong Trieu town, Quang Ninh province. The study was conducted through in-depth interviews with 136 farm households (62 linked and 74 unlinked) with the direct interview survey method, and collected data were processed using SPSS. The binary logit model was used to analyze the factors affecting the decision of farm households to join the linkage. The research results showed that the linkage brought benefits to both the farm households and the enterprise, but there are still some limitations. The decision of households to join the linkage was influenced by factors such as production area, production experience, agricultural extension training, and membership in a cooperative. In order to promote economic linkages between farm households and the enterprise, the solutions that need to be implemented include: i) Raising farmers' awareness about the role of linkages in potato production and selling; ii) Strengthening support for farmers in terms of the enterprise providing technology and inputs for production and purchasing potatoes; and iii) Encouraging the local government to support the establishment of cooperatives, strengthen agricultural extension training to attract households to join the linkage, and increase the efficiency of potato production in the town.
