The invention discloses an energy supervision information sharing system and an energy supervision information sharing method. The energy supervision information sharing system comprises an energy consumption meter, a lower level energy consumption supervision platform, a communication module and an upper level energy supervision information sharing platform, wherein the energy consumption meter is used to collect energy consumption data of energy consumption mechanisms, the lower level energy consumption supervision platform is used to collect and sort the energy consumption data in a designated area, collected by the energy consumption meter, the upper level energy supervision information sharing platform is used in summary presentation and analysis sharing of the energy consumption data of each energy consumption mechanism on the lower level, and the communication module is used in a network communication connection between the lower level energy consumption supervision platform and the upper level energy supervision information sharing platform. The energy supervision information sharing method includes: collecting the energy consumption data, encrypting and transmitting the energy consumption data, auditing and settling the energy consumption data after decrypting and storing the energy consumption data, and finally achieving the sharing of the energy consumption data. The energy supervision information sharing system and the energy supervision information sharing method completely eradicate human error during the submission process, achieve fully automatic updating of the energy consumption data, and improve submission efficiency.
