The invention discloses a regional private shared parking place utilization rate evaluation method comprising the following steps that all the operation records of different parking places in the same region in a statistical period are acquired; whether every natural day has an open record is judged; the total number of working days and the total number of holidays having the operation records of each parking place are calculated; a state average time distribution table is acquired; the effective time utilization rate, the shared time utilization rate and the ideal time utilization rate of the working days and the holidays of the single parking place are calculated; a calculation model of the regional shared parking utilization rate is established by combining the regional parking place space area occupation, the preset proportionality coefficient of the working days and the proportionality coefficient of the holidays; and the calculation result is calculated by using each established calculation model, and the evaluation result is acquired through contrast to the established regional private shared parking place utilization rate evaluation criterion. The regional private shared parking place utilization rate can be improved so that the evaluation method is a regional parking time and space resource utilization rate evaluation means suitable for the new mode of private shared parking resource.
