Therefore, to advance the study on innovation of urban planning institution, the emphases should be in-depth analysis on the existent specific institutional arrangements, and reflection on theoretical methodology, nuclear concepts and logistic series of the institution system. The starting point of urban planning institutional innovation could base on the existent planning operational system, such as development planning, distribution planning and specific construction planning etc., or relate to urban construction and other relevant institutional arrangements. However, the emphasis should be establishing the mechanism of distributing, harmonizing and balancing different interests, rights.
