The boy, named locally as Diarmuid Frazer, died in hospital on Friday evening.
The six-year-old was crossing the busy Railway Street with his mother and his twin brother, Cormac, when the incident occurred just after 3.30pm.
His brother was taken to hospital for treatment, however, he has since been discharged.
Both were pupils in primary two at Ballymacward Primary and the school held a special assembly for the boys on Thursday.
Speaking to UTV, councillor Pat Catney said: "The whole community is shocked and devastated - there are no words to say how great the sorrow is.
"We are thinking of the family and the brother of the little child. It's just awful and tragic.
"I know as a local community we will rally for the family," the SDLP representative said.
DUP councillor Scott Carson added: "Lots of people across Lisburn city are thinking and praying for the family at this very difficult time.
"It came as a shock that one of the twins succumbed to his injuries and certainly it is a life that has been cut short too early.
"My thoughts and prayers are with all involved in this incident and the heartbroken family."
The police have appealed for witnesses to the accident to contact investigating officers on the new contact number 101.
