The structure of the food market in recent decades has had a significant impact on the agricultural sector. Meanwhile, Traditional markets play an important action in the food distribution system in Indonesia, including in Malang Regency. This study aims to examine the influence of the vegetable market structure on agricultural sustainability and to analyze how changes in market structure affect the sustainability of agricultural practices. This research used a quantitative method. The quantitative data analysis in this study was conducted using multiple linear regression, supported by several statistical tests to ensure the robustness of the results. This research was conducted at Landungsari Market, Dau District, Malang Regency, during the period from January to March 2025. This research indicated that the vegetable market structure significantly influences agricultural sustainability in Dau District, Malang Regency. A calculated t-value exceeding the t-table value, combined with a probability of less than 0.05, indicates that changes in market structure, particularly those resulting from competition between local and incoming traders have a tangible impact on farmers' income. These changes affect not only the level of competition and industry efficiency but also the sustainability of farming practices, especially as vegetable production volumes rise. Thus, the study confirms that market structure dynamics are a dominant factor influencing the sustainability of the agricultural system in the region. Local governments need to pay attention to the competitive dynamics between local and migrant traders, as changes in market structure have been shown to affect farmers' incomes, and the sustainability of agricultural practices.
