This paper investigates the link between firm headquarters location and firm stock return co-movements in a sample of Chinese firms spanning the years 1999 to 2007. The empirical results show a strong co-movement pattern of firms located in the same province. Moreover, both firm-level and provincial-level factors are found to influence this co-movement, including firm size and ownership structure at firm level and GDP per capita and financial depth at provincial level. A subsample of firms listed in the Shenzhen Stock Exchange shows that better firm-level information quality reduces local co-movements.
