Currently，China’s legislation is at an inflection point from “quantitative legislation” to “qualitative legislation”，and the concrete practice of local rule of law has become a key part of the basic strategy of national rule of law. Chongqing Rail Transit Regulations were promulgated in 2011，aiming to provide good legal guidance for the construction and management of chongqing rail transit. However，with the improvement of chongqing rail transit management level，“chongqing rail transit regulations” are also faced with new system requirements. The results of post-legislation evaluation show that this regulation not only has the shortcomings of rationality，operability，effectiveness，technicality and local characteristics，but also needs to be improved in the specific construction system and operation management system. In order to better provide rail transit services，it is necessary to make appropriate adjustments with The Times to ensure its better performance. Is therefore，in the comparison reference，suzhou，Beijing，shenzhen，chengdu and other cities after the latest practice，Suggestions to revise and supplement The Regulations Of Chongqing Rail Transit，refine the construction fund，obligatory responsibility and operation period，etc in order to perfect the orbit transportation construction terms，adjust the professional qualifications，pollution prevention and control and relief program to improve the management of rail transit clause，and suggestion of organization management，competition mechanism and terms shall be modified. Hope to use scientific post-legislation evaluation system to insight into the implementation of regulations and put forward Suggestions to improve the level of local legislation by improving the rule of law index.
