A non-zero-sum game means that under different strategy combinations, the sum of the interests of each game party is an uncertain variable, so it is also called a variable-sum game.
If the selection of certain strategies can increase the sum of the interests of all parties and at the same time increase the interests of all parties, then there may be a situation where the parties cooperate with each other.
Therefore, in a non-zero-sum game, there is the possibility of cooperation between the parties in the game.
Many problems in the international economy are non-zero-sum game problems, that is, the interests of all parties in the international economy do not necessarily conflict with each other.
In this situation, one’s own gains are not equal to others’ losses, and even one’s own happiness may not be based on the pain of others. There is a possibility of win-win, and then cooperation.
