In recent years, many advanced countries promote performance-oriented management system as the core mission for government reforms. But the implementation experience of these countries revealed that there still exists a weakness in the integration of performance measurement and budget. One of the major reasons is the failure to establish a relationship between ”performance” and ”accountability.” Our country has introduced the performance management system following that of the United States government for six years, and we have encountered similar problems. Furthermore, there is a management system that parallels projects and budgets in our government organization, which makes it even more difficult to integrate performance management information and feedback performance management information into our decision-making process. This article first discusses the necessity of integrating government projects and budgets according to experiences of other countries and laws of our country. The article further lists several core issues and suggestions on information integration to serve as references for future studies.
