The purpose of this paper is to clarify the relationship of cyclical fluctuation between cocoon prices and cocoon production from 1982 to 1994. Both the former and the latter were treated by statistical analysis. At first, the use of coefficient of correlation was used. Next in use of ALMON'S LAG was used to calculate the result. As result, the influence of cocoon production against cocoon price appeared one year after most strongly and next, two years after. Namely, in comparing from 1955 to 1981 and from 1982 to 1994, it appears that the correspondense of price in the latter is stronger than in the former. Finally, it is induced that sericultural farm households have given consideration to four facters for cocoon production, namely : 1) fluctuation of cocoon prices, 2) more opportunity of getting cash income from non agricultural works, 3) sericultural income in comparison with other field products and 4) improvement of productivity in cocoon production.
