There are economic regions at various areal levels, including sectional and comprehensive ones,and other types of economic regions formed spontaneously or by means of policy decision-making. The economic regions discussed in the literatures of economic geography and regional eco-nomics in China are usually refering to comprehensive ones as the territorial units of national eco-nomic activities. According to the function , objective and principles of economic regionalization, four types of economic regions are grouped based on homogenous economic regions,economic co-operation regions,urban economic regions and administrative-economic regions. However the ideal comprehensive economic region should be the integration of the above mentioned four types of economic regions. As the division of different types of economic regions has only a meaning for research ,some kinds of organization forms of economic activity regions should be establised to bring the role of the economic regions into practice. The basic forms are as follows:(1)The economic activities are under the macroscopic guidance and regulation by the central and local governments,according to the administrative regions.(2) To establish multi-heads' organization for economic coordination by planning on the basis of areal reorganization which break the administrative regions.(3)To or-ganize economic cooperation and alliance beween cross-jurisdictional regions on a basis of volun- tart' and mutual benefit.
