This paper analyzed Grey Correlation Degree between infrastructures and city comprehensive scale of 22 cities in Xinjiang by Comprehensive Grey Relation Degree (CGCD) method with city date in 1978-2007. The results showed: CGCD of 22 cites belong to middle correlation and strong correlation types; Cities of strong correlation type mainly are in Economic Belt on the Northern Slop of the Tianshan Mountains, and cities of middle correlation type are in South of Xinjiang; CGCD of cities have increased gradually but less in 1997 - 2007.
