The administrative dispute resolution mechanism is composed of administrative reconsideration，administrative litigation and petition system. In recent years，the causes for administrative disputes tended to be more complicated，which not only intensified the difficulty of solving these disputes but also exposed disadvantages of the existing practice，in which priority was given first to petition，second to litigation and the least to reconsideration. The solution of the problem depends on the improvement of the orientation and functions of these three systems and the reinforcement of the dispute solution structure in which priority should be given to reconsideration，litigation should serve as decision and petition as supplement.
