Notes: , the average price in the first three periods; , the average number of allocated seats in the first three periods; , the initial price; , the initial number of allocated seats before optimization; , the increase rate of the average price compared with initial values; , the increase rate of the average number of allocated seats compared with initial values. The unit of price is Chinese Yuan.
