An interesting observation! - 增加到了300只时，只有20%在活动着
We also observed the similar phenomenon in geographic systems. For a small geographic system like a city, there are only 20% in the head, while 80% in the tail, following the head/tail breaks thinking: https://en.wikipedia.org/wiki/Head/tail_Breaks
For a large geographic system like a country, 10% in the head while 90% in the tail. https://www.researchgate.net/publication/1910404_Street_Hierarchies_A_Minority_of_Streets_Account_for_A_Majority_of_Traffic_Flow

Wow, wow, wow, very interesting. I just scan the abstract of your paper. Very interesting. You got to read this blog of mine, 人类困境的数学解释 http://blog.sciencenet.cn/blog-414978-1015644.html , and the related papers mentioned in this blog: "Growth, innovation, scaling, and the pace of life in cities"
Well, probably you are familiar with this study. The first author of that paper published another one on Science two years ago, talking about streets, traffic, etc in cities, trying to explain the power law. I will read your paper in detail later. Thank you very much for sharing.
