Liu Yu and Zhu Chengquan wrote in the Economist, No. 3, 2022, that western ecological economics was established under the vision of building the social and economic system into the biophysical world. This ontological basis is strongly opposite to the growth paradigm of standard economics. However, the interpretation of economic processes in ecological economics is still quite close to the neoclassical mechanism. By accepting the allocation efficiency of markets, the core of neoclassical economics has been brought into the framework of ecological economics, leading to a fundamental divergence between "old" economic methods and "new" ecological economic ideas. The critical thought of Marx's political economics reveals how ecological crisis relates to the main driving force of economic growth and to the tendency of equating growth with development. Only by returning to the original context of "capital critique" can we correctly understand the essence of ecological crisis. Systemic changes are necessary to create a socio-economic order that meets human needs rather than capital needs and protect the natural ecological conditions that sustain life.
