Using a gravity equation, this study examines the Linder hypothesis in agricultural trade. Rather than utilizing per capita income similarity generally used in this area, we used the climatic similarity as a proxy variable of the similarity of demand structure between countries. To examine the issue, imports data from 39 countries regarding fruits and 36 countries regarding vegetables from 1999 to 2008 to Korean market was used. This study finds that strong statistical evidence of the climatic similarity increases the agricultural trade between countries, which could be considered as evidence of the Linder hypothesis explaining agricultural trade.
