The NIMBY conflicts caused by the construction of garbage incineration plants frequently occur. This paper proposes that the main reason is the dual-game structure. In the dual games, the administrative departments form a strong incentive for chief officials, while the public and the enterprises winning the bidding of NIMBY projects in the jurisdiction form a weak incentive for the officials, which thus affect the behaviors of local officials. Consequently, the governance over NIMBY conflicts falls into a weird cycle characterized by "closed decision-making" and"call-off remediation". To optimize the governance of such conflicts, this paper puts forward three paths: reforming the decision-making mechanism of the government, promoting the government’s ability in information disposal, and improving the public interest litigation system concerning environmental issues.
