NGC 7023 have been observed in ^(12)CO and ^(13)CO (J=1→ 0) molecular line emissions. It possesses bipolar molecular outflows which are moving out both eastward and westward in Right Ascension with a velocity range of ±9 ㎞s^(-1) with an inclination of ∼80° The mass loss rate is ∼10^(-5)M◎_(yr)^(-1) with an assumed stellar wind velocity of ∼100㎞s^(-1); the dynamical age of this outflow is ∼5.5×10⁴ years. The bipolar molecular outflows would be collimated by the molecular disk surrounding HD 200775, which is explained by either the velocity gradient of ∼0.25 ㎞s^(-1) are min^(-1) in the position-velocity map of ^(12)CO along the Declination or the peak temperature maps of both ^(12)CO and ^(12)CO. The outflows also yield high density regions at their ends, producing the region of the low mass star formation.
