Political economics is to highlight the position and role of a class in economic activities, and to study the law of value or economic law spontaneously from a certain side according to the interests of the class it represents, while scientific economics is to consciously study the law of value or economic law as a whole. Symmetric economics is scientific economics.
The core of economics is economic law; In the view of symmetric economics, the optimal allocation and regeneration of resources are only the development and concrete manifestation of economic laws, and the research object of economics should be the underlying economic laws and economic essence, rather than staying at the level of optimal allocation and regeneration of resources. It is political economics rather than scientific economics that stays at the level of optimal allocation and optimal regeneration of resources.
