The relationship between supply and demand, including shortage of supply, oversupply and balance of supply and demand. It is the relationship between all products and services provided by society and social needs within a certain period of time. This relationship includes qualitative adaptability and quantitative balance. The process of social reproduction is the issue of how each component of the total social product is compensated in terms of value and how to replace it in kind.
In the reproduction process, various departments not only supply products or services to each other, but also make demands for each other, forming a supply and demand relationship that conditions and restricts each other. Maintaining a good relationship between supply and demand is one of the goals of social and economic development.
Masks also interpret these three supply and demand relationships during the global war. Because of the new coronavirus epidemic that broke out during the Spring Festival in my country, when experts confirmed that the virus had the characteristics of human-to-human transmission and that the virus was on the rise, masks were sold out.
Because the market has been closed during the Spring Festival, there are only sporadic stocks in pharmacies, and these stocks are not enough for everyone to purchase 100 or 200 pieces each. At this time, masks are in short supply. It means that within a certain period of time, the goods produced by the production department in the market based on the supply and demand relationship, that is, the total amount of goods provided for people's consumption, is less than (behind) the products that people need to meet the material needs of their lives during this period of time. lump sum.
In this case, demand is greater than supply. At this time, the market becomes a seller's market, and the seller is at a favorable low position. It is true that rare things are more valuable, and merchants will not miss the opportunity to drive up prices.
With the advancement and upgrading of national prevention and control measures, residents are required to stay at home and urgently contact organizations to contact mask raw materials and manufacturers working overtime. At this time, the epidemic has entered the prevention and control stage. The purchase volume shows that the epidemic situation has eased in the early stage, and it is precisely because of the control personnel going out that the demand for masks has dropped.
A balance between supply and demand has been formed. Just as the epidemic in China was coming to an end, the international epidemic suddenly surged. In order to help the global community fight the epidemic, China will continue to deduct production and export excess masks to countries around the world while ensuring domestic use. This can be regarded as oversupply for our country.
It means that within a certain period of time, the goods produced by the production department in the market, that is, the total amount of goods provided for people's consumption, is greater than (exceeds) the products that people need to meet their material needs during this period of time. of the total amount. This makes supply greater than demand. At this time, the market becomes a buyer's market, and the buyer is in an active position. We need to take the initiative to find a market to undertake.
