Does that chain store on Qunar.com have uniform prices across the country?

No.

According to the query on the Global Travel Network, national chain hotels only have unified decoration standards, unified decoration styles, unified items used, and unified service standards and specifications, but this does not mean unified prices, because Different cities, different locations, hotel rents and labor costs vary greatly. For example, the same Hanting Hotel can be sold for more than 350 yuan in Beijing, but can only be sold for 200 yuan in Jinan. This is determined by the market. There is no uniform price on any platform, including Qunar.com.
