Transaction cost, also known as transaction cost, was put forward by KOS (R.H., 1937), winner of the Nobel Prize in Economics. The fundamental argument of transaction cost theory is to explain the essence of enterprises. Due to the professional division of labor and the operation of market price function in the economic system, the phenomenon of professional division of labor has appeared; However, the cost of using the market price function is relatively high, forming an enterprise mechanism, which is an organization formed by human beings in pursuit of economic efficiency. Since transaction costs generally refer to all the expenses incurred in promoting transactions, it is difficult to clearly define and list them. Different transactions often involve different kinds of transaction costs.
