Based on a questionnaire of among over 3，000 applicants who were drawing lots for buying cars，the survey was aimed to investigate the opinion on the policy of limiting car-purchasing. The result shows that the policy plays a positive role in easing traffic congestion，but at the same time，the public needs of car-purchasing cannot be satisfied promptly，and it is not a rare phenomenon that some people draw the lots for a quite long time but in vain. Because the applicants feel but vague and distant hope and ever increasing uncertainty in buying car，they have a relatively low opinion of the current policy. On the basis of the survey，the report suggests that the purpose and means of limitation on car-purchasing be clarified，the fairness of the policy be redefined，and the breakthrough point of the gross adjustment and controlling be identified. So far as a soon improvement of the policy is concerned，the report suggests advancing the possible creation of suburban license-plate，and to allocate car quota by taking family as a unit.
