Abstract
In this paper, we analyzed the demand for dry shiitake mushrooms on the basis of their usage. Following the analysis, we can state the following.
1. The Japanese dry shiitake mushroom and Chinese dry shiitake mushroom are found to be neither substitutional nor complementary, probably because their usage patterns are different.
2. Japanese dry shiitake mushrooms meant for domestic consumption and those meant for export are sometimes used substitutionally and sometimes complementarily. When the mushrooms had similar forms, colors, and gloss were harvested around the same time and in particular, were more or less similarly priced, they were used substitutionally. Further, when both the sizes and the prices of the mushrooms were similar, they were used complementarily.
