“Steedman's Critique” refers to a challenge to Marx's theory of value, proposed by British economist Ian Steedman, based on the “negative value” that could arise in the case of joint production. International academia has engaged in heated discussions on this critique, which has been criticized from different perspectives. However, these efforts have not fundamentally solved the problem. In our opinion, there is no valid contribution in the logic of Steedman's “negative value” theory, but the concept of “negative value” itself is of great significance from the perspective of theoretical economics, and it also provides an important theoretical support for the development of resource and environmental economics.
Another solution is neglected for it signifies negative price, which is not in accordance with reality.
