本文建構了一個多階段的賽局模型，以刻畫工會與不確定型態產品創新，並且觀察了獨占廠商以及雙占廠商的情況，在這之間，也可以觀察到工會力量對於工資談判的影響。而由於是不確定型態，使得我們要以期望利潤去觀察，因此我們必須導入投資成功機率和投資失敗機率，為了簡化觀察，我們也假設了投資金額越高，投資成功機率就越高，再去觀察模型裡面分別帶來不同的效果，如工會力量，產品替代性若上升，都會使我們投資金額降低，造成我們投資成功機率變小。

This research constructs a model, to describe how unions and uncertain product innovation. Affect investment under situation of monopoly and duopoly. In addition, the union power on wage bargaining is allowed. Because the result of innovation is uncertain, we simply assume that higher investment a higher probability of success on innovation. The results show that if the wage bargaining power of a union increases and product substitution increases, the investment on innovation declines and so the probability of achieving successful innovation lowers.
