다국어 초록 (Multilingual Abstract)

Since Japanese government took reformative measures of public investment in the period of 2000s, this paper investigates how the economic effects of public investments has improved in the period of 2000s. The empirical findings do not show that the output elasticity with respect to public capital has been higher in the 2000s than that of 1990s. Rather, some output elasticity estimates for 2000s has lowered after the advent of year 2000. In addition, the impact of public capital on the productivity of private capital has not improved in the 2000s compared with that of 1990s in Japan. Another major finding shows that the crowding-out effect of public investment has been stronger in the 2000s than before. Those findings imply that the reforms done by Japanese government in the 2000s regarding public investment do not spread out into the private aggregate production and investment.
