Abstract: With the target of maximizing time efficiency and minimizing disaster loss, emergency supplies focus on the cooperation of emergency capacity reserve between government and enterprise. Under three different conditions (without any measures, punishment, punishment and subsidies in parallel), an evolutionary game analysis is conducted in terms of emergency productivity reserve between the government and the enterprises. Analysis shows that under certain conditions, the government′s inspection cost, regular or irregular, government′s subsidies and punishment, are the key factors that influence the cooperation of both sides. And through a numerical example to validate the conclusion, the emergency productivity reserve strategy is analyzed.
