Government downsizing is not only a part of reorganizing initiative of government levels and structure, but also is a step of recreating the ability system of government. The primary problem is how to reinvent the structure and ability of government in order to implement the functionalism and fragmentation of the reorganizing initiative. We should recreate the develop framework of political, economy and human relationship in the local-government by redistributing administration region. On the other hand, referring to the theories of inter government relationships, regional government theory as well as the practice of system construction in the France, Germany, Japan and US, we can integrate the local branches of different central government units. By doing that, the Province, region or intermediary organization can act as the central government, to unify and supervise the affairs which involve several local governments. Furthermore, applying the limited purpose government theory, special purpose government theory, regional government theory and intermediate institution theory, we can merge the multi-area affairs of city-region. By encouraging local governments to perform further integrating and cooperating, the mechanism of operationalism government can be built and the effect of growth coalition will emerge. It will favor the establishment of a multifunctional government cooperation system and with this; we will step into a new age of local government operation and development.
