The purpose of this paper is to study regional characteristics of the land improvement project from the viewpoint of economics. I make econometric models of rice production in Yamagata and Ibaragi, and simulate with these models to judge how the land improvement projects affect the rice production when the projects are carried out. The reason why I select these prefectures is that Yamagata is blessed with the natural conditions, such as climates and soil, for rice production, while Ibaragi is abundant in opportunities of employment. The findings are as follows.The simulation shows that in Yamagata the land productivity has improved more noticeably than the labour productivity, whereas in Ibaragi there has been a more improvement in the labour productivity. These results suggest that the projects mainly affect the rice yield in the regions where natural conditions are favorable, and affect the labour force in the regions where opportunities of employment are abundant.Land improvement projects have been carried out according to almost the same standards all over Japan. But the effects vary from region to region, since different regions have different natural and social conditions.
