2. Finance is the study of economic activities in the financial currency circulation market, such as futures, stocks, bonds, insurance, banking, venture capital, etc.
3. The major of general economics seen in universities mainly focuses on academic research and covers a wide range, so it is generally not aimed at specific and practical economic disciplines.
4. Finance originated from economics, and now it has been relatively independent from economics, with 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 construct a market equilibrium system from the rational behavior of micro-subjects (irrational behavior, such as anchoring effect, is also taken into account in behavioral financial testing). Explore the mechanism and function of financial system in intertemporal resource allocation. Finance has created a unique research method in economics, such as arbitrage-free analysis, which is commonly used in the pricing of financial assets. This method is actually more specific than supply and demand analysis in economics and easier to realize in the market. In addition, it is very important that the concept of expectation of neoclassical economics development has been well applied in finance. Finance considers random factors in the market, so the expectations of market participants play an important role in it and depend on mathematics.
