Eco-capitalism is an important theoretical school in the western academic circles. Some of its theoretical viewpoints are of great significance for us to promote the construction of ecological civilization. However, it is not suitable to propose a solution to the current ecological crisis from the Market-and Technology-oriented thinking or to propose the view of seeing capital and ecology as being consistent based on the current ecological situation in the capitalist world, which ignores the history of the capital exploitation on the global ecological resources and the reality of capitalist countries transferring ecological crisis elsewhere, and fails to discover the anti-ecological essence of the capital and capitalism. The capital logic of the capitalist private ownership and the mode of production exploit the nature in a costless way. It is only possible to realize the unity of the capital and ecology when the capital is controlled and activated ecologically under the socialist system.
