Outline of Final Research Achievements	The purpose of this study is to clarify structural changes in Japanese agriculture, including regional differences, by statistical analysis and field survey. It is another important issue to clarify the changes of group farming systems based on rural community that have been established throughout Japan as a result of the structural policy. An analysis of the 2020 Agriculture and Forestry Census revealed that Japanese agriculture has been shrinking and is on the verge of collapse, and that regional differences in structural change are widening. The field survey revealed the following facts. In flat paddy fields, large-scale operations are expanding their scale further by renting farmland. On the other hand, group farming systems in hilly and mountainous areas were facing difficulties as they were unable to secure successors. Collaboration among community farms and mergers of them has occurred, which local agricultural policy supported this phenomenon.

Academic Significance and Societal Importance of the Research Achievements	危機的状況にある日本農業の正確な姿を地域差を含めて把握するとともに、農業構造変動が現地で具体的にどのような形で生じているかを観察することで、構造変動のプロセスを明らかにするという点に本研究の学術的な意義がある。また、政策の影響を受けて設立された集落営農がどのような道筋を辿っているのかを明らかにすることは政策評価という点でも貢献するところがある。この研究に基づいて農業政策、特に構造政策の方向性について提言を行うことができる点にも社会的な意義があると考えている。
