The findings indicate that both the public investment quality and efficiency of Vietnam reveal certain limitations, and no evidence can be found for the effectiveness of investment expenditures in short terms, although a long-term relation exists between the public investment and economic growth. A few comprehensive solutions to investment enhancement until 2020 are as follows: (i) Rationally adjusting investment structures and portfolios, (ii) Improving institutional environment; (iii) Controlling investment efficiency; and (iv) Modernizing the monitoring system for the public investment.
