Agricultural Structural Changes and Differences in Production Structure by Farmland Size in Citrus Farms: Analysis of Citrus Farms from the 2020 Agricultural Census

Abstract

I analyzed the changes in agricultural structure and differences in productivity by farmland size in citrus producing areas by using the agricultural census. In recent years, agriculture in citrus production areas has been declining severely. In particular, the situation in islands in the Seto Inland Sea is so serious that it can be described as the collapse of local agriculture. It is suggested that the current productivity gap by farmland size is shifting from the medium-size advantage structure, which was pointed out before, to the large-scale advantage structure. But, in production areas such as the islands in the Seto Inland Sea, where the labor force has been declining precipitously, the large-scale advantage structure is weak.
