Main obstacles are manifested as follows:lack of effective policy to accelerate economic zone development, failure to carry out some good macro policy, having no excellent policy evaluation system, and without correcting mistakes of policy circulation, etc. The reasons for these obstacles can be summed up as subjective aspects, objective aspects, and institutional aspects. Under the guidance of scientific development concepts, if we want to overcome these obstacles, we shall choose feasible approaches to optimize public policy.
