: The existing literature shows that, due to locality and familiarity, spatial investor–firm adjacency plays a key role in determining stock investor attention, as proxied by the location where investors initiate an Internet search of the ticker symbol. This paper investigates whether Chinese stock markets exhibit the same pattern observed in the U.S. market—demand for a firm’s information can exert strong effects on the stock market response during earnings announcements of the firm. Specifically, for each Chinese publicly listed firm, this paper constructs a dynamic local attention ratio that divides the search volume generated within the province where the firm is registered by the contemporaneous nationwide search volume consisting of 31 provinces in total. During 2011–2018 in China’s A-share market, it was found that the local attention measure leads the market response around annual earnings announcement dates. For firms with higher local attention, trading is more active before the announcement, and the price changes can better predict incoming earnings news. At the announcement, while trading remains active, the predictivity of price changes for earnings becomes weaker. Furthermore, we only found evidence that supports the local information advantage argument in explaining the locality of Chinese investors’ attention.
