What does economics mainly talk about?

Economics is a study of "need" and "satisfaction" of "human life and human social development". Where are the roots of all economic phenomena? Because, no matter the emergence, existence and extension of any economic phenomenon, there is a "need" reason behind it, so the fundamental reason of all economic phenomena is: need! That is, the "need" of social civilization and progress and the "need" of human life. Therefore, economic research should start with "needs", grasp the main line of "needs", and carry out economic theory innovation before economic development and social progress. The process of economic development is to meet the needs of social progress and personal life. In other words, social and economic development must meet the "needs" of social progress and personal life at the same time, and the two cannot be neglected. Because the "need" of personal life and the "need" of social development are two completely different forms, and the relationship between these two "needs" is interactive, interactive and complementary. To "meet" the "needs" of social civilization and progress by means of "overall planning and operation"; The "need" of personal life is accomplished through "transaction". "Transaction" can give people a fuller sense of satisfaction on the premise of "market prosperity"; Only by "overall planning and operation" can we "meet" the society's demand for highly civilized creation on the premise of "rich resources". Market prosperity is the reason for abundant resources, which is the basis of social material civilization construction, which is the premise of more profound changes in market prosperity. Therefore, the market economy cannot be developed in isolation, and the planned economy is not indispensable. We should operate the mechanism of "economic development" according to the transformation of conditions, that is, design an economic system that can fully release this "energy" in the process of social "civilization and progress" according to the energy state of "material foundation". Similarly, we can design an economic system that can be more fully satisfied according to the allowable state of "market space"
