This paper analyzed the structure of public conflicts formed in Pyeongchang's bid process to host the 2018 Winter Olympics by exploring mechanism of public conflicts caused among a wide-range of policy participants. Particular attention was paid to behaviors and belief systems of policy participants and groups who caused policy conflicts in the process. To do so, this study's analysis was based upon a series of three stages of conflict development identified by Park, Jaehwan(1992). Policy implications derived from the study are as follows: first, conflicts were originated in a goal-oriented contradiction among policy groups seeking their interests; second, conflict groups tried to secure superior positions through the formation of complementary relationship with government, strengthen their solidarity on the basis of their shared belief systems and form public opinion regarding their position through strategic means such as a rally and announcement of statements; and third, activities of policy competition among interest groups made an attempt at change in their recognition and goal of policy orientation.
