To finance investment in economic infrastructure, the government extensively utilized a fiscal investment and loan programme (FILP). The FILP was a budgetary system prepared in addition to the central government’s general budget, and was financed mainly by postal savings until fiscal year 2000. Figure 6 shows the proportion of FILP according to usage during the years 1955-84. Spending for social infrastructure was maintained at a low level, at around 30 per cent, while substantial amounts were allocated to economic infrastructure.
