A Game-Theory Approach to the Taiwan Strait Issue:
Nuclear Threat and Limited War

Abstract: The paper extends the basic framework of the Taiwan Strait game among Taiwan
authority, mainland China and the U.S. to explore Sino-U.S. conflict-level issues. By incorporating
nuclear war option in the game, we derive the subgame perfect Nash equilibrium and prove that
mainland China possesses a credible nuclear threat so that if it declares war against Taiwan, America
will not intervene by force. Further incorporation of the PRC’s limited war choice manifests that a
full-fledged war maintains the credibility of Beijing’s nuclear war threat, while limited war action of
Beijing loses the credibility. Conclusions are also drawn on the chance of a large-scale Sino-U.S.
military conflict and the PRC’s choice of conflict level in face of external shocks.
Key words: Taiwan Strait Issue, Game, Nuclear Threat, Limited War

台海问题的博弈分析:核威慑与有限战争
内容简介:本文扩展了台海问题博弈分析的的基本模型,以考虑中美冲突的不同规模以
及核威胁的可置信性问题。通过在博弈方的策略集中引入核战争选择,我们证明:以边缘台
独政策为特征的子博弈精练均衡仍然存在并唯一;祖国大陆存在一个可置信的核威慑,使得
大陆在出兵台湾之时,美国一定不会出兵干涉。之后我们进一步扩展了大陆的策略集以考虑
有限战争的可能,我们证明:若大陆选择全面战争,其核威慑仍是可置信的;但若选择有限
战争,则其核威慑的可置信性将会丧失。文章其它结论包括:中美大规模冲突不可能出现;
存在特定的机制,使得完全战争和有限战争分别成为大陆的最优选择。
