it can be seen from the live broadcast penetration of the category and the matching of supply and demand, as follows:

1. Live broadcast penetration of the category: that is, the proportion of the category in the live broadcast e-commerce. If the penetration rate is high, it means that this category has been involved by many anchors and businesses, and the competitive pressure is also great, so the scarcity of the track is relatively low. On the other hand, if the permeability is very low, it shows that this category still has great potential and space, and the track scarcity is relatively high.

2. Matching supply and demand: If a category can meet the needs of both merchants and consumers, then the track scarcity of this category is relatively high. For example, clothing, beauty cosmetics and other categories not only have higher gross profit and low price concessions, but also have higher purchase frequency and impulsive consumption.
