タイのコメ生産費調査と生産費およびコメ生産費のタイ・日比較

Abstract

One of the most important causes of international rice trade conflicts is the difference in the efficiency of rice production among countries. This efficency reflects the average rice production cost. In this paper the rice production cost and its survey in Thailand, where rice can be produced at the lowest cost in the world, are explained based on the related Thai government publications in Thai language and the results of author's past interview surveys of the Thai government officials in charge of the rice production cost survey. Then, Thai rice production cost items are adjusted and modified in order to compare them with Japanese rice production cost items. Comparing the costs, the reasons why the differences between the costs arise are sought, and possiblities by which high Japanese rice production costs can be reduced are investigated.
