摘要

This paper introduces a new approach to the studies of complex systems, which is based on. conceptual entanglement of science and philosophy. On the basis of 'two umbrellas' by Checkland, we raise a 'third umbrella', namely, self-organization and evolution, which extends systems thinking to complex system thinking. This paper also talks about the mechanisms of the operation and evolution of complex systems, puts forth an interactive model of three mechanisms and two feedback loops and finally presents its implication to the management of social organizations.
