Given the criticism on the function and existence of the local councils, this study mainly tries to analyze Adaption Possibility and Adaption Time for the municipal ordinance. The data collected for the 18 sessions from the 282nd session in 2018 to the 299th session for three years are empirically tested(n =1,482). The study result indicates that almost all variables among ten variables in each category for the bill turn-in subjective, committee, bill turn-in characteristic, session-related opportunity are statistically significant. While the unrevised passage of the submitted ordinance is likely to have less time than submitted non-ordinance, ordinance adaption time is different in each session. The comparison with data analysis outcomes between all sessions and individual sessions shows that ordinance adoption capacity for the council is better than ordinance non-adoption capacity. In the bill adoption capacity, the unrevised passage of the ordinance is likely to improve as a session goes by. In the bill non-adoption capacity, the submitted ordinance is more likely to pass in a shorter time for all sessions. The submitted ordinance is more likely to have much lagged time.
