This study focuses on financial characteristics and giving back to region at each business development stage in rural community businesses (CBs) in hilly and mountainous areas. We analyze the sweet potato community business in Iinan-cho, Shimane Prefecture, as a case study. Our key results are as follows: (1) The CB main company had increased its superiority in sales to the market, along with the gradual expansion of sales through the development of the CB. (2) Along with the development of CB, the CB main company had expanded ordinary income by securing profits and subsidies and had increased returns to each stake holder (SH) participating in the CB. (3) These results suggest that changes in giving back to the region are based on multiple factors such as unique characteristics of each SH, conditions under which SHs participate in CB, and changes in business environment.
