CEVAP:

Neo-Marxism is not actually a theory on its own. Neo-Marxists consider themselves working within the Marxist intellectual tradition, but seek to broaden or revise Marxist thought to address topics not specifically addressed by Marx. For instance, neo-Marxists may offer an analysis of the state, economy, or politics that move beyond the simple infrastructure/superstructure interaction. They may combine classical Marxist analysis with forms of sociology, social-psychology, or even feminism.

Also, neo-Marxism tends to take a less rigid and more modern approach to analyzing a situation, focusing especially on the issues of underdeveloped and core-developed country relations.
