This article analyzed the different trends of production indices of eight m
anufacturing subsectors during the economic crisis period (July 1997-Decemb
er 1998). All the indices declined until May 1998, but their recovery patte
rns markedly differed. The index of the agriculture-related subgroup (food
and beverage, fertilizer: petroleum refinery) recovered quickly and reached
a historically highest level in December 1998, while those of the other gr
oups continuously declined. Therefore, the production index of the agricult
ure-related group was 82% higher than the pre-crisis level, while that of t
he light-industry group (textile, furniture, miscellaneous) was 10% lower a
nd that of the heavy-industry group (cement, iron and steer, machinery) bec
ame less than half. The paper estimated equations for subsectors, conducted
simulation experiments, and determined how different causes (noneconomic i
mpact, rapid depreciation and shrinkage of imports, general economic tl-end
, strong export activity, and others) affected the trends of subsectoral pr
oduction and employment.
