The theory of“state-society”relationship of Marx is a hot topic in China’s academic circles. Scholars believe that this theory has three main stages of development which are the country originates from the society, the country separates from and overtakes the society, the society gradually returns to the society. However, on specific issues, this theory has different aspects for research. The theory of“state?society”relationship of Marx has important enlightening significance to the goal of building and better governing“a strong country and a strong society”in China. It is noticed that there are some defects in research, such as studying in isolation rather than as a whole, consciously or unconsciously put Engels’relevant theories aside, using the concept of“civil society”to explain the realistic problems in contemporary China and lacking discussion about the important role played by the Chinese Communist Party.
