The Research of the Alliance Portfolio Chaos Evolution Model

Alliance portfolio is an effective organizational form for enterprise in technical innovation,and this paper elaborates the complexity characters of the alliance portfolio,and the structure fractal,process fractal and function fractal which exist in alliance portfolio system are revealed based on chaos theory,and it reflects the characteristics of instability,bifurcation,transition in the evolution process.As the external environment ability and internal power change from weak to strong,the alliance portfolio will gradually enter chaos,and different changes of the factors result in different evolving of the alliance portfolio.Through controlling effectively the factors of the alliance portfolio,the evolution direction can be grasped.
