中文摘要：

企业选择竞争行为应对潜在竞争威胁是确保企业盈利的要素之一。针对此问题，利用博弈论展开定量研究。首先通过引入两阶段博弈形式化企业竞争战略选择过程，并用二层规划刻画该博弈过程，通过求解该二层二次规划获得两期博弈的均衡解；据此对处于价格竞争市场中的两个企业竞争行为选择过程进行仿真，验证了根据两期博弈进行的企业竞争行为的分类和选择的正确性。

英文摘要：

The enterprises choose the competition action in face of the threat from the potential counterpart. The research on this problem in China is mainly qualitative analysis. Firstly the model for strategic choice is built based on the two-stage game. Secondly, the process of the game is described based on convex quadratic hilevel programming problem and the equilibrium of the game found out by solving the convex quadratic bilevel programming problem. Finally, the whole process of the game is simulated by an example of price competition to prove the correctness of the classification of the strategic choice.
