"Two dimension and four modes" construction of government credit

Expounding the dual main boundary of central-local with its outside form and practical functions,the paper provided the necessity and possibility to take government credit body as an example to analyze the four kinds of relationship construction and modes of central and local credit produced by the interaction process of governments combining with periodicity of credit under this deconstruction.The practical strategy of credit construction was provided as well.These modes generally correspond with time,and they are linear.Their evolvement has incrementality and sluggishness,and the boundary is obscure.
