What are the characteristics of art market and art marketing that are different from other commodity markets and marketing?

Art market and artistic marketing are different from other commodity markets and marketing. Works of art are different from ordinary practical goods in life. They have their own uniqueness. They meet the spiritual needs of human beings, not the survival needs. But at the same time, it must be affirmed that its basic attribute is commodity and belongs to a member of the commodity family. Very special, but there is no need to make it too special, let alone mysterious. Need people from the old art world to give a good answer. Just recently, I was reading the book "Exploring the Art Market" edited by Mr. Linton, which made a thorough discussion on this issue. The author, Mr. Linton, has made in-depth research on the art commodity market, witnessed and participated in various stories in the art business community, and his views on the art market are worth reading. Art belongs to the category of commodities, and should have many common characteristics with the market operation of general commodities, so we have to mention the most traditional marketing theory: 4P theory, that is, product, price, place and promotion, which is regarded as the classic theory of marketing specialty. The problem to be solved by 4P theory is that commodities enter the market and systematically deal with the whole process of commodity and currency exchange between commodity producers and commodity consumers. Let's take a concrete look at art as a commodity and apply the 4P principle of marketing theory in marketing.
