Based on the GBEE-CRAS2018，32 CSR reports released by the Shanghai municipal state-owned enterprises are collected，assessed and analyzed in this research. After annual comparison and comparison with the average level of companies all over China and the level of central SOEs，the stage characteristics of these reports are summarized with relevant suggestions for the reporting preparation. It is found that the report number and quality have gradually improved，and a regular mechanism for report releasing has been initially established. The reports show obvious industry characteristics. However，there is still much room for improvement in social responsibility management and report innovation. The Shanghai municipal state-owned enterprises need to further enhance the institutionalized and standardized social responsibility information disclosure，closely combine their business with the sustainable development background，national development strategy and the overall orientation of Shanghai urban development，and disclose higher quality social responsibility information on the basis of fully identifying the demands of stakeholders，so as to enhance the core competitiveness of enterprises.
