Water information disclosure is an important factor for water-sensitive companies to send information to capital market and gain returns. Whether or how the companies disclose water information becomes a focus for government and stakeholders. This paper, based on Shanghai\|listed chemical companies data from 2016 to 2018, establishes a multiple regression model to study the impacts of enterprise features, internal management, financial status and external factors on water information disclosure. Results show that enterprise size, listed periods, capital intensity, gross capital returns, public supervision pressure are positively related to water information disclosure level, but board proportion and Tobin Q value are negatively related to it. Equity concentration, asset debt rate, equipment renewal rate and local economic level have no significant impact on it. This paper, aiming at increasing water information disclosure quality, presents suggestions on establishing water information disclosure system, optimizing internal management and financial status and intensifying external supervision.
