Dr. XU Jianming started with introducing the concept of exploitation in the economic theories. He thought this concept was heavily ridden by ideologies, and it had disappeared from the contemporary standardized economic textbooks. Dave Friedman even thought it was not worth discussing. Dr. XU claimed that what he tried to do was to prove in competitive equilibrium, exploitation and morality coexisted and constituted the starting point in terms of logical reasoning.

Dr. XU discovered that when marginal productivity was high enough, and then there was no limits to the utilities of workers or farmers, there was no exploitation, or moral economy.

Professor CAI Jiming thought the issue of exploitation was certainly important. One of the reasons that we are eradicating private ownership today is the connection between exploitation and private ownership. He objected this connection and the labour value theory based on it.

Professor MO Zhihong thought the proposal of a concept was supposed to deal with specific problems. She thought the concept was insufficient to explain the reality and therefore, should be either abandoned or reexamined.
