The Quota Employment system in China has played a positive role in promoting employment of persons with disabilities and the realization of individual value since its establishment. However，relevant data show that the employment rate of out of the quota system is not high and this system has failed to solve the problem effectively at present. This situation is mainly due to some problems with the quota system，for example，law is too general and not operable，and there are no effective punishment/incentive mechanisms. Given this，it is necessary to raise awareness among persons with disabilities as well as the society in regard to right to employment based on the “human rights model of disability”；at the same time，the design and implementation of the quota system and related legal mechanisms need to be strengthened so as to ensure effective implementation of the quota system.
