从国内和国际背景来看，“占领华尔街”运动都有其发生的必然性，这场运动从“资本积累、政治合法性、资本主义文明和地缘文化”三个层面折射出资本主义世界体系的矛盾与危机：即资本主义体系陷入资本积累困境，资本主义积累方式的弊端日益显现；资本主义体系陷入政治合法性危机，资本主义自我调节的手段逐渐失效；资本主义体系陷入资本主义文明危机和地缘文化困境，资本主义精神的光环逐渐褪色。若资本主义体系依然按照当下的模式来运转，那么这些抗议运动的“蝴蝶效应”就将发展成为动摇其社会制度的大地震。
“Occupy Wall Street” movement has its inevitability as viewed from the domestic and international background. The movement reflects the contradictions and crisis of the capitalist world system from the three levels of capital accumulation，political legitimacy and capitalist civilization and geo-cultural. That is，the capitalist world system plunged into the plight of accumulation of capital，and the drawbacks of the way of capitalist accumulation became increasingly apparent；lapsed into the plight of political legitimacy，and capitalist means of self-regulation gradually failed；fell into a capitalist civilization crisis and the plight of the geo-cultural，so aura of the spirit of capitalism is gradually fading. If the capitalist system still works in accordance with the current mode，the “butterfly effect” of the protest movement will develop into a large earthquake to shake the social system.
