Abstract: In this study, the export quantities of 54 plant-based agricultural products produced in Türkiye during the period 2007–2019 were analyzed using panel data methods. The effects of production, imports, the degree of self-sufficiency, and human consumption per capita on exports were investigated. Prior to model estimation, multicollinearity, slope homogeneity, cross-sectional dependence, and panel unit root assumptions were examined. Three alternative panel data models: fixed-effects, random-effects and pooled ordinary least squares models were estimated. Among the models, random-effects model was selected based on the model selection test procedure. The results indicated that imports, the degree of self-sufficiency, and human consumption per capita had significant positive effects on exports, whereas the effect of production was not statistically significant. The panel causality analysis revealed a unidirectional causal relationship from production to exports and from exports to imports, while bidirectional causality was identified between exports and the degree of self-sufficiency, between exports and human consumption per capita, and between exports and the imports.
