Abstract: Foster believes that the development of contemporary capitalism is experiencing a severe "epoch-making crisis",which is embodied in the following three aspects. In the economic direction,he has insight into the economic monopoly,stagnation and financialization at the global level. Moreover,he finds that these are associated with global labor arbitrage. From the aspect of social direction,he perceives the instability of the working class's work and life has become a global problem,and the instability is even more dangerous than the era in which Marx and Engels were. In terms of ecological direction,he points out that the infinite expansion of capitalist production breaks through the bearing limits of the natural environment.,and the degradation of the ecological environment,ecological imbalances and the resulting global ecological inequalities are increasing.Foster's research and interpretation of the crisis of contemporary capitalism has a clear sense of problems,which has a critical reference value for China's current economic and social development and ecological civilization construction.
