电子政务是管理创新和技术创新的结合,管理创新先于技术创新。提出了以政务目标为主导的电子政务多级目标体系结构和具有顺序特性的电子政务建设模式;在引入行政系统状态转移模型基础上,定义电子政务成熟度指标、成熟度空间、效益向量,在成熟度空间建立度量电子政务效益的数学模型;分析了提高电子政务实际效益的途径。 E-government is a combination of management innovation and technological innovation. Management innovation precedes technological innovation. This paper proposes a multi-level target architecture of e-government and a e-government construction mode with sequential features, which is dominated by government goals. Based on the introduction of the state transition model of administrative systems, we define e-government maturity indicators, maturity space and benefit vectors. Maturity space to establish a mathematical model to measure the effectiveness of e-government; analysis of ways to improve the actual effectiveness of e-government.
