The failure to fully achieve the public policy goal is a phenomenon worthy of indepth discussion. Different from the incremental construction period, "negative effect" in the process of urban renewal due to complex property rights, less benefits, and imperfect institutions have not yet been valued and recognized, i.e., intrinsic conflicts or improper quantification of the target, failure in practice, repeated games in rule-making, or promulgation without deduction and pilot practice hence leading to the higher implementation cost and the greater execution resistance. Such phenomena are caused by cost and time constraints, the rationality of goals and rules, the promotion efforts of implementation, together with the restrained executable power and the insurmountable "uncertainty," resulting in the goal expectation to be disappointed formally or substantially. To eliminatethe "negative effect," it depends on the construction of an open governance system, explicit real cost, improved cognition, judgment, and action ability, as well as guiding all parties utility function consistent with the social utility function, and improving the error correction mechanism, thereby improve implementation performance.
