Final answer:
Trade in the Shang dynasty differed from trade in Egypt and Mesopotamia due to the absence of currency and the domination of bronze trade.
Step-by-step explanation:
In the Shang dynasty, trade was primarily done through a barter system, where goods were exchanged for other goods without the use of currency. In Egypt and Mesopotamia, trade was more sophisticated and involved the use of currencies such as gold and silver. Additionally, the Shang dynasty had a monopoly on the production and trade of bronze, which greatly influenced their economy and relations with neighboring regions.
