Abstract: Discrepancy and balance are two developmental goals which must be taken into account.The discrepancy is the inner motive force of economic growth, and also is the way to balanced development.By analysing the alteration of provincial discrepancy combined with the increasing speed, this paper indicates that there is a relation between them.During the earlier stage of provincial discrepant process.the total economic amount is limited.Only the superior area can be invested concentratively so that the speed increases quickly, which enlarges the provincial discrepancy.During the later stage, discrepancy surpasses the provincial bearable capability and turns to be an obstacle.The speed drops down and discrepant controlling becomes the most important task.so only proper discrepancy can coordinate the contradiction between them.After establishing a functional relation, the interaction and the dynamic changing trends were revealed through an approachable model, directed by the appropriate discrepancy, a warning level can be set up to make a policy for discrepant adjustment.An example proved the method.When shandong'S maximal discrepancy of GDP per capita arrived at $ 7028.6.it got into the warning state and gained the maximal speed of 19.05% per year.If discrepancy is small.the concentrative developmental policy should be adopted to pick up the speed.When it is getting large and approaching the warning level, discrepant controlling should be adopted to rationalize it.
