What did Alexander's expedition bring to the people of the East?

First, deep suffering.

This is first and foremost, and there is no doubt, because this is a war of aggression and plunder. Two famous cities, Tyre and Persepolis, were destroyed in the Crusade, and a large-scale massacre took place in Central Asia.

Second, living resources are occupied.

Alexander's expedition started Hellenization, and a large number of Greek immigrants poured into the East, which changed the local social structure to varying degrees. Most obviously, in Egypt and Bactria, a few Greeks ruled the majority of the local people and became the owners of local land, property and resources, which also had an impact on the local people.

Say two neutral or benign.

I. Two-way cultural exchange

The rulers vigorously advocated and developed culture, and with the influx of immigrants, Greece and the local people had different degrees of two-way cultural exchanges, which lasted for hundreds of years. Alexandria library and its schools, Gandhara art, etc. of Ptolemy dynasty in Egypt. Are among the best, which undoubtedly promoted the local.

Second, trade and economic activities have increased relatively.

The Persian imperial government stored a lot of gold. After the arrival of Lydia, these currencies were cast into many regional or unified currencies and put into the market, which caused the price increase to a certain extent, but undoubtedly strengthened the economic activity, opened up various markets at that time, removed the obstacles caused by political factors, greatly stimulated local trade and had an impact on the opening of the Silk Road later.
