economics

Economics is a theory that studies the law of production, circulation, distribution and consumption of value. The research object of economics is the same objective law as that of natural science and other social sciences.

Economy is the creation, transformation and realization of value; Human economic activities are activities that create, transform and realize value and meet the needs of human material and cultural life. Economics is a theory that studies the law of human economic activities, that is, the law of creation, transformation and realization of value-the law of economic development, which is divided into political economics and scientific economics. 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 of human economic activities as a whole with scientific methods. The new normal economics is scientific economics. The core of economics is economic law. In the view of new normal economics, the optimal allocation and regeneration of resources are only the development and concrete manifestation of economic laws. The research object of economics should be the economic law and essence behind the optimal allocation and regeneration of resources, 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. To study the law of economic development, we must study economic phenomena as a whole. Macroeconomics and microeconomics are two symmetrical aspects in a unified economy. Therefore, under the framework of the new normal economic paradigm, there are macroeconomics and microeconomics, but there is no difference between macroeconomics and microeconomics. Political economics always divides economics into macroeconomics and microeconomics.

microeconomics

Microeconomics ("Microeconomics" is a free translation of the Greek word "μ ι κ ρ ο", which means "small"), also known as individual economics, is a branch of modern economics, which mainly focuses on a single economic unit (single producer, single consumer, single market economic activity). Microeconomics is an economic theory that studies the economic behavior of a single economic unit in society and how to determine the individual value of the corresponding economic variables. Also known as market economics or price theory.

Microeconomics is an economic theory that studies the economic behavior of a single economic unit in society and how to determine the individual value of the corresponding economic variables. Analyze the economic behavior of individual economic units, on this basis, study the operation of market mechanism and its role in the allocation of economic resources in modern western economic society, and put forward microeconomic policies to correct market failure; Paying attention to the exchange process between individuals and organizations in society, its basic problem is the decision of resource allocation, and its basic theory is the theory of determining relative prices through supply and demand. Therefore, the main scope of microeconomics includes consumer choice, supplier supply and income distribution. Also known as market economics or price theory. The core theory of microeconomics is price theory. The central idea is that free exchange can often maximize the use of resources. In this case, the allocation of resources is considered as pareto efficient's.

Macroeconomics

Macroeconomics, taking the activities of the general process of the national economy as the research object, mainly examines the total economic output such as the total level of employment and gross national income. Therefore, macroeconomics is also called employment theory or income theory.

Macroeconomics studies the utilization of economic resources, including national income determination theory, employment theory, inflation theory, economic cycle theory, economic growth theory, fiscal and monetary policy.

Learn micro reasons first, then macro reasons;

Because there is a logical process.

Microeconomics, starting from the balance of supply and demand, talks about the behavior of consumers and producers, the two main bodies of the market; Starting from the relationship between consumers and producers, this paper introduces the product market and the factor market; Then find the general equilibrium through these two markets;

Due to information asymmetry and externalities, there will be market failure in the market; When the market fails, a government macro-control is needed, which leads to the relevant contents of macroeconomics at the moment.

The picture posted is my notes on macroeconomics, and you can refer to this logic. The blue box is macroeconomics and the purple box is microeconomics.
