Evolutionary game among local governments of extreme floods emergency management in Huaihe River Basin

摘要

This paper applies the evolutionary game (EG) theory to extreme floods emergency management in Huihe River Basin, and analyzes replicator dynamics and its evolutionary stable strategy (ESS) among local governmental agents, and solves the function of replicator dynamics and ESS, also does some stability analysis. This study suggests that: (1) the evolutionary game among local governmental agents has two evolutionary stable strategies, but only one optimal ESS; (2) Increasing penalties would decreases the proportion of PC strategy in a group of local governmental agents; (3) The minimum standards of penalty must exceed the extra cost paid by AC strategy.
