英文摘要：

Public policy performance loss is a problem needing prompt solutions. Through case study and with Shifang Decision-making Dilemma as research object, this paper answers the theoretical questions of the process, reasons and internal mechanism of the Shifang Mo-Cu Project decision making performance loss. Firstly, it combs the process consisting of cognitive divergence, benefit divergence, street protest and performance loss. On this basis, it reviews the theory of public decision making performance loss. It defines the connotations of public policy performance loss and its research value, finding that insufficient public val- ue construction is the fundamental reason for policy performance loss; cognitive divergence, shared reality and other social-psychological factors are the internal mechanical factors for the loss; and insufficient perfor- mance leadership and cooperated production concepts are the main reasons for the loss. It advocates that gov- ernment must address and cope with the profound changes in social cognitive fields.
