According to the Basic Standards for Internal Control of Enterprises and their guidelines jointly formulated by five state ministries and commissions including the Ministry of Finance, as well as the Opinions on Accelerating the Internal Control System Building of Enterprises in the System of the Shanghai Municipal State-owned Assets Supervision and Administration Commission (SHSASAC) released by SHSASAC, SIG organized the self evaluation of internal control in 2019. With focus on five elements-internal environment, risk assessment, control activities, information and communication, and internal supervision, SIG comprehensively evaluated its internal control design and operation.

SIG fully integrated three defensive forces, and organized functional departments to establish an internal control self evaluation working group to analyze relevant systems and process manuals, and verify the effectiveness of internal control design and execution. Through self checks and spot checks, SIG enhanced the basic concept of "all employee involvement" in risk control and the business philosophy of "practice and steadiness"; formed an integrated check mechanism, objectively evaluated the effectiveness of the internal control of SIG and relevant departments, found and prevented the weaknesses of internal control; and kept implementing and improving the internal control system to promote the effective operation of the internal control system.
