Abstract：

This is a status report of the project on befalf of the BEPCⅡ team. BEPCⅡ is a major upgrade of the BEPC (Beijing Electron-Positron Collider). It is a double-ring e⁺-e^－collider as well as a synchrotron radiation (SR) source with its outer ring, or SR ring. As a collider, BEPCⅡ operates in the beam energy region of 1—2.3 GeV with design luminosity of 1×10³³cm^－2s^－1at 1.89 GeV. As a light source, the SR ring operates at 2.5 GeV and 250 mA. Construction of the project started in the beginning of 2004. Installation of the storage ring components was completed in October 2007. Commissioning is in progress. There are still many issues for further studies before reach to 3×10³²cm^－2s^－1.
