The overall quality of WPVPCPs is high, but there is still room for improvement. Specifically, the overall score of primary variables such as policy perspective and policy level is low, and the score of secondary variables of policy nature, policy object, policy tool and policy prescription is unbalanced. These aspects may be the entry point for effective improvement of WPV, so they should be taken seriously in the development and optimization of relevant policies in the future.
