The productivity change in rice production and cost-benefit analysis after the execution of the farm land consolidation project: statistical analysis about effectiveness of farm land consolidation project part 2

摘要

This paper aims at analyzing the effect of the farm land consolidation project by using the statistical method. The findings are as follows. Firstly, the land productivity hardly changes, but the labor productivity improves drastically due to the project. As for the capital productivity, the conditions of the productivity change vary in the management scale. Secondly, by the cost-benefit analysis in the project complete area, it is found out that average annual internal rate of return is higher than 4 percent, in spite of being left many small scale farmers in the project area. However, this rate does not reach the rate that presumed at the time of the plan. Thirdly, the important points to improve the cost reduction effect of the project are to accumulate the land on farmers who hope for the scale expansion, to prevent the excessive investment of the agricultural machine, to give priority to the wet or less inclined area, and to construct the waterway with pipeline system.
