Abstract: This paper provides regional level estimates of total factor productivity (TFP) growth and its components in Turkish agriculture. Using a translog stochastic frontier model with monotonicity constraints, we decompose TFP growth into technical change and efficiency change across 26 NUTS-2 regions over 2013–2020. We also examine the relationship between technical efficiency and trade openness by integrating regional agricultural trade openness into the model as an (in)efficiency driver. These contributions address gaps in the existing literature by revealing regional TFP disparities in Türkiye and investigating the previously understudied link between technical efficiency and trade openness. Additionally, we explicitly control for climatic effects, including average temperature and precipitation in the frontier, to isolate weather-driven fluctuations from inefficiency. Our results highlight pronounced regional disparities, with export-oriented regions exhibiting higher efficiency. Moreover, trade openness is significantly and positively associated with technical efficiency, suggesting that greater integration with external markets may foster TFP growth in the Turkish agricultural sector. Climate variables show nuanced impacts, with moderate temperature and rainfall positively affecting agricultural output, while extreme conditions negatively impact yields. TFP growth is predominantly driven by technical change, while efficiency change slightly detracts from overall productivity gains.
