Difference Between Exchange and Transaction

It's a matter of definition. The two terms are confusingly defined, or there is no strictly accepted definition.

For example, there are two definitions of a transaction:

1.A transaction is an exchange of value between two parties in the medium of money and clothing.

2.Transaction, also known as ** and exchange, is the act of mutual exchange between buyers and sellers of valuable goods and services. It can be a process in which money is used as a medium of exchange, or it can be bartered, such as a scalper for three pigs.

Definition 2 says Transaction = Exchange = **, which can be either currency or not.

Obviously, you teachers are another way of defining it. But it's rare.

Transactions have a commercial dimension, and in most cases there is a generally accepted system of valuation.

In the process of exchange, the value of the exchanged material is mostly determined by the two parties to the exchange. I don't think it's necessary to qualify like that. Because when exchanging, we will also consider the value of the object itself, of course, there is an equivalent exchange and an unequal exchange in practice.

Because value is difficult to determine, value is related to human needs and the scarcity of goods, the value of water in the desert is obviously higher than that of diamonds.

The transaction is the unit of measurement of the exchange, the exchange is a process, the transaction is a result, and the content of the transaction must include the transaction time, place, transaction conditions, the maintenance of the relevant legal system, and two valuable items;

This definition is again an attack that emerged from **

In short, the definition is conventional, recognized, and the definition in the dictionary is more recognized. Of course, as the times change, the connotation (definition) and extension of words change.

Of course, I tend to think of transactions and exchanges as the same thing, which saves me a lot of trouble because I can remember one less word. Thus, exchange = trade = ** = buy and sell = each gives the other what he has and what the other needs (goods or actions).

The transaction is the unit of measurement of the exchange, the exchange is a process, the transaction is a result, and the content of the transaction must include the transaction time, place, transaction conditions, the maintenance of the relevant legal system, and two valuable items;

The essence of exchange is to bury Shuhe to exchange useless things for useful things, and to fulfill others and strengthen themselves; In other words, to replace useful things with more useful things, to achieve others and satisfy yourself.

In general, exchanges can be divided into 4 categories:

The various activities generated in the production process and the exchange of various capacities. For example, in the production process, the exchange of activities and abilities between workers in the process of division of labor and cooperation.

Product exchange in the curve of the production process. For example, the exchange of raw materials or semi-finished products between processes in the production process within the same production unit.

Before the product finally enters the consumer field, the exchange of products in the process of production, transportation, packaging, storage and other processes between different production units.

The exchange that takes place directly for consumption, that is, the exchange in which the product enters the final consumption sphere. The first type of exchange belongs to the direct production process; The latter three types of exchange are the intermediate links that link production, distribution, and consumption.

Exchange is an indispensable link in the process of social reproduction, a bridge linking production and the distribution and consumption determined by production. In the process of social reproduction, the nature, depth, breadth and mode of exchange are determined by the nature, level of development and structure of production.

During the past "May Day" holiday, the hotel costs skyrocketed several times, which made many people sigh. In this case, a form of "zero-cost" accommodation has quietly spread on the Internet - exchange tourism, in which two strangers travel to each other's cities and stay in each other's homes for free, saving the cost of accommodation.

The reporter checked the relevant social platforms and found that since the end of April, many netizens have posted looking for "exchange tourism objects", and many have been "exchanged" successfully. However, compared to the interest shown by some people in exchange tourism, more netizens have a wait-and-see or skeptical attitude, believing that exchanging with strangers is "too unsafe".

Judging from the survey, there are two main ways to exchange tourism before the eye-cavity faction, one is to exchange at the same time on the agreed date; The other is to stagger the time exchange, that is, Party A will first check into Party B's house, and the latter will be responsible for reception, and after some time, Party B will stay at Party A's house. In addition to the way individuals post on social platforms, there are also some "exchange travel platforms" on the Internet, which hide a lot of tricks.

According to the experts interviewed, this form of exchange tourism is popular with young people because it has many advantages such as expanding social networks and reducing the cost of tourism. However, the only thing to note is that the exchange tourism model is still in the "embryonic" stage in China, and the relevant laws and regulations, mass concepts, etc. are incomplete, and there are greater potential risks, which need to be paid attention to.
