に伴って links a development or event to a change that accompanies it, often in formal writing.
The idea
Attach に伴って or formal に伴い to a noun or dictionary-form verb. の may nominalize a verb: 上がるのに伴って. Before a noun use に伴う.

No Japanese device voice is available. You can still read the text and use the linked listening resources.
Watch out
The second event should be connected to the first; this is not a general marker for two unrelated simultaneous actions. It does not necessarily imply proportional change.
