This paper analyses the operations of the Japanese multinational corporatio
ns in the world economy by constructing and estimating a Japanese foreign d
irect investment system. This system models the determinants of manufacturi
ng foreign direct investment (FDI), the trade between Japan and her oversea
s affiliates as well as the sales of the manufacturing subsidiaries and tho
se of the trading subsidiaries. The error-correction modelling techniques a
re adopted for estimation in order to capture both the short- and long-run
adjustment processes. Finally, simulations are conducted on the model to an
alyse the effects of changes in the world economy. (C) 2000 Elsevier Scienc
