| Outline of Final Research Achievements |
Agricultural public infrastructure (API), such as irrigation and drainage facility, farm road, and consolidated farmland, is aging and deteriorating due to a lack of investment budget for renewal projects. This study aims to evaluate future influences of deteriorated API by using the dynamic-spatial computable-general-equilibrium (CGE) model. In order to introduce an influence of API change, the prediction model of capital stocks was developed and the functions showing relation between agricultural productivity and API were empirically estimated.
The simulation results demonstrate that the asset management measures which try to prolong the lifetime of facilities are effective, but these policy measures are not enough to renovate all aging facilities. Furthermore, there are discord between famer's and national benefit caused by renovation of API. Based on above prediction on future situations, policy implications on public investment are discussed.
