The effects of socioeconomic factors on secular trends in suicide rates in Japan for the periods 1953-72 and 1973-86 were investigated using twelve socioeconomic indicators. Multiple regression analysis showed that the socioeconomic indicators affecting suicide rates were not identical in the two periods. The rates in both sexes in 1953-72 were closely related to unemployment rate and the labour force but between 1973 and 1986, divorce rate and the proportion in tertiary industry were most influential. The changes reflect the socioeconomic changes in industrial structure in Japan in transition from an industrial to a service economy.
利用12项社会经济指标，研究了1953 - 1972年和1973 - 1986年期间社会经济因素对日本自杀率长期趋势的影响。多元回归分析表明，两个时期影响自杀率的社会经济指标并不相同。1953 - 1972年男女自杀率均与失业率和劳动力密切相关，但在1973年至1986年期间，离婚率和第三产业占比的影响最大。这些变化反映了日本从工业经济向服务经济转型过程中产业结构的社会经济变化。
