In a broader sense, finance belongs to the field of economic research, and finance is the study of economic activities in the financial currency circulation market (such as futures, stocks, bonds, insurance banks, venture capital, etc.).

The major of general economics seen in universities mainly focuses on academic research, which covers a wide range of topics, so it is generally not aimed at specific and practical economic disciplines. However, many new branches of economics have been derived from the basic theoretical research of economics, such as information economics, environmental economics (non-market methods analysis method is a very important extension) and so on.

From another perspective, finance originated from economics, but now it has been relatively independent from economics and has a relatively systematic research method.

At the same time, Modern finance still stays in the framework of neoclassical analysis of modern economics. Its characteristic is to start with the rational behavior of micro-subjects (irrational behavior, such as anchoring effect, is also taken into account in behavioral finance examination), to build a market equilibrium system considering time and uncertain factors, and to investigate the mechanism and role of financial system in the intertemporal allocation of resources.

Finance has created a unique research method in economics. For example, the no-arbitrage analysis commonly used in the pricing of financial assets is actually more specific than the analysis of supply and demand in economics and easier to realize in the market.

Extended information:

Finance and finance are products of modern economy. In ancient times, it was mainly farming and agricultural economy, mainly barter and simple currency circulation, and there was no finance and finance at all. For example, in China, some financial theories are scattered in various ancient books on the issue of "financial goods". As an independent discipline, it was first formed in the west and called "Money Banking". The finance in modern China was introduced from the west, and there were various money bank theories from classical economics to modern economics.

the content of financial research is extremely rich. It is not limited to the study of financial theory, but also includes the history of finance, the history of financial theory, the contemporary financial theories of the East and the West, and the separate and comparative study of financial systems and financial policies in various countries. The theories of securities, trust and insurance are also within the scope of financial research.

The main research topics in financial theory are: the essence and function of money and its position and role in economy; The forms of credit, the functions of banks and their position and role in the economy; The nature and function of interest; Characteristics and laws of currency circulation organized on the basis of modern bank credit; The theory of macro-control of economic life through money and so on.

economics is a theory that studies the law of human economic activities, that is, the law of value creation, transformation and realization-the law of economic development, which is divided into two types: political economics and scientific economics.

in the view of symmetric economics, the optimal allocation and optimal regeneration of resources are only the development and concrete manifestation of economic laws, and the object of economics should be the economic laws and economic essence behind the optimal allocation and optimal regeneration of resources, rather than staying at the level of optimal allocation and optimal 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 the economic phenomenon as a whole. Macroeconomics and microeconomics are two symmetrical aspects in a unified economy, so in the framework of scientific symmetrical economics paradigm, there are macroeconomics and microeconomics, but there is no difference between macroeconomics and microeconomics. Political economics always divides economics into macroeconomics and microeconomics.

1. Economy is economy and frugality in production or life. The former includes saving funds, material materials and labor, etc. In the final analysis, it is saving labor time, that is, using as little labor as possible to produce as many achievements as possible that society needs.
