Narrative: We landed and began the long taxi to the west side of the airport. Once on a long straight portion of the taxi; First Officer contacted Operations for gate confirmation and an entry spot. We were told that the gate was open and told to call when approaching spot XX. We continued our taxi; crossed the bridge; and got clearance from Ground control to 'taxi X to park'. As we approached the ramp area Y; the First Officer and I monitored the Operations frequency. When we got close to spot XY the First Officer asked for clearance to enter at spot XX but was informed that it was occupied and that we were to use spot XZ (the adjacent entry spot to XX) instead.We entered at spot XZ; as instructed; and set the parking brake since the aircraft at spot XX was blocking the remainder of our taxi route to our gate. As we pulled into spot XZ we noticed the reason for the aircraft stoppage at spot XX: a CRJ had been pushed from a gate just in front of that aircraft. That recently-pushed aircraft got underway quickly. Approximately 15 seconds after setting the parking brake; and with no other radio transmissions observed on the ramp control frequency; that aircraft began moving forward. I released the parking brake; applied a small amount of throttle; and began my taxi forward with intent to turn left within approximately 40 ft. I went to rotate the tiller to the left and just prior gave a quick look out my left side window to confirm that we had no other aircraft or vehicles impeding our movement. I noticed movement in my periphery from left to right. It was fast moving. There were still no observed taxi or parking clearances observed between the parking brake set and the beginning of my forward movement. I applied brakes and closed the throttle. The aircraft to our left was moving at a speed of at least 10 kts.; and likely 14-17 kts. by my approximation. We remained in place until the speeding aircraft was far enough ahead (on our same planned taxi route) to safely continue forward. We took note of the time; tail number; parking gate; and operator of the aircraft that had effectively cut us off in an unsafe manner inside of the critical area. Aircraft Y parked at [gate]. We continued past [gate] to park at our gate.I can't speak to the mindset of the captain in control of Aircraft Y. I don't know what he or she heard; thought they heard; etc. I do know that they were not an emergency aircraft and that their actions put themselves; their crew; their passengers; my crew; and my passengers all in danger. Unnecessarily so. The cause for this incident seems to rely solely on the PIC of Aircraft Y being negligent and disregarding the safety of hundreds of people for the purpose of self-interest.Suggestions include a serious reprimand; at minimum; for the PIC of Aircraft Y. It's not hard to taxi safely. The disregard for safety in this incident is unwelcome and has no place in the aviation industry.




Synopsis: E175 flight crew reported a CRJ taxied toward them at high speed in an unsafe manner; which resulted in a critical ground conflict.
