Bargaining between supervising and subordinate agencies is a ubiquitous phenomenon in governmental processes，taking place in specific organizational context and structured by the rules of the game. Hence，bureaucratic bargaining provides a port of entry from which to observe government institutions and behaviors. In the proposed sequential game of bargaining between a principal（e.g. a provincial environmental protection agency）and an agent（e.g. a municipal environmental agency），we identify two strategies——“routine” vs. “mobilizational” mode——available to the principal. The agent can choose from three response strategies in its subsequent move：“formal bargaining”，“informal bargaining” or “quasi-exit”. When the mobilizational mode is adopted by the principal，quasi-exit is the best choice for the agent；if the routine mode is present，the agent has more flexibility in choosing among the three alternatives.
