Abstract
In recent years, the formation of large-scale rice-vegetable paddy farming complexes has become an issue in Hokkaido. In this context, the Southern Hokkaido Area, where this complex management is being developed, has attracted attention. In this paper, we examine the agricultural structure of the Southern Hokkaido Area and clarify the conditions for the existence of large-scale paddy farming complexes. The results are summarized as follows.
First, in the Southern Hokkaido Area, （1） the liquidation of leased land is progressing and the scale of management is expanding, and （2） the weight of vegetable cultivation is high. （3） The Iburi region area is a representative area for the development of combined rice and vegetable farming.
Second, the conditions for the existence of large-scale paddy farming complexes in X town in the Iburi region area: （1） Employed several permanent workers for open field vegetable crops., and （2） large-area farmland were formed for each paddy rice and open-air vegetable crop under employment-type corporate management.
