英文摘要：

Employing the content analysis and taking Fortune 500 firms in China as our research sample we examine the influence of vision and mission on firm value under different circumstances, especially the financial crisis. We find that the existence of vision and mission increases the firm value under relative stable circumstance. Meanwhile, we introduce the concept of consistence of vision and mission, and investigate its effect on the firm value. We find that the consistence of vision and mission decreases firm value under the condition of higher level uncertainty, but the effect is not significant when the circumstance is relatively stable.
