Abstract

The purpose of this paper is to measure the land capital stock of the paddy field and analyze its effects on the rice yield in Hokkaido after 1963. The total amount of land capital stock of paddy fields in Hokkaido became the highest in 1993, 1.6 times that of 1963. After that, the amount of land capital has decreased, and it is 1.5 times as much as in 2001 compared to the level of 1963. The land capital stock per unit of land has increased as much as 1.8 times as that of 1963. We compared the rice yield in years of cold weather damage with normal years to investigate the effects of land capital stock. It has become clear that land capital stock has a positive effect on rice yield in recent years.
