Aggregation Structure of Trading Networks

The distribution of trading agents on the trading network is not uniform, but presents various patterns of aggregation. At different levels of the trading system, trading agents choose different forms of aggregation. Layered aggregation is a common feature of complex systems. The more complex the system, the more layered aggregation structures there are. Each additional layered structure will promote the synergy within the system, and the efficiency of the system will be greatly improved as a result.
