According to the present development of new energy vehicles, the risk of the new energy vehicles project is analyzed, the risk evaluation index system is established and the rough sets theory is used to reduce the index system in this paper; and exponential whitenization weight function under grey uncertain character of the assessment information is constructed; then the improved grey hierarchy evaluation method is used to appraise the implementation of the risk of new energy vehicles project in Henan province; finally, based on the comprehensive value the risk of implementing new energy vehicles project is advanced. The risk is relatively large at present. And there are some proposals for further development.
