通过理论分析,合理界定了“大部制”这一全新概念的内涵与范畴,并提出“大部制”改革的现实背景与理论渊源。此次改革是在我国改革开放以来实行的五次政府机构改革及电子政务建设卓有成效的背景下进行的,在信息化时代探索新一轮改革的路径模式,要充分发挥电子政务在“大部制”改革中的工具媒介和推动作用。 Through theoretical analysis, the connotation and scope of the new concept of “majority system” are rationally defined and the realistic background and theoretical origin of the “majority system” reform are proposed. This reform is carried out under the background of the five government agencies reform and the e-government construction effective since the reform and opening up in our country. In the information age, we should explore the path model of a new round of reform. We should give full play to the e- System of “medium” and the promotion of the role of the media.
