How much?

Or does it refer to materials, labor, freight, and other consumption? I think that the general wholesale price under free market circulation has already explained the cost of paper.

I just don't know the specific process in the middle, how large a batch of paper is produced, how many people are used and then split, and the logistics to various places for distribution. I just randomly compared the Alibaba wholesale Deli paper is 500 sheets of A4 paper in a pack, 10 packs or more for 22, the price in 2018 (not only time, different A4 papers also have different qualities, brand effects and costs). This is the general online price. Maybe the dealer can get about 20 yuan per pack, which is about 4 cents per A4 paper. It feels that printing used to be 1 or 2 cents per sheet. With the passage of time, including RMB inflation, it is so cheap. It seems that the production efficiency and logistics distribution standards have been greatly improved. Suddenly I have an urge to use A4 paper to calculate the problem.
