Abstract：The development of rare earth oranometallic complexes involving bicyclopentadienyl types was briefly reviewed. The developments in catalytic performance of ethylene polymerization by rare earth oranometallic complexes involving bicyclopentadienyl types such as unbridged lanthanidocene complexes without cocatalyst，bridged bis（cyclopentadienyl） rare earth complexes and unbridged lanthanidocene complexes，were mainly introduced. These findings suggested that the rare earth oranometallic complexes involving bicyclopentadienyl types had high catalytic activity in ethylene polymerization and have a great potential of development.

Key words：metallocene；ethylene；polymerization；catalytic activity
