Abstract

The static status and dynamic trend of the market structure in the international wheat trade market are empirically analyzed. The export inequality level empirically proved to be high compared to import inequality level. And such states have been maintained since 2001 until 2014. Although the concentration level of export side seems to be easing, the international wheat market remains imperfect competitive market. Moreover, overall imperfect competitive status over 2002-2014 has been worsened compared to 2001 level. The main reasons are that the overall trends of the imports concentration is reduced more than those of the export concentration level.
