Zusammenfassung:	Provided is a method for manufacturing asymmetric hollow fiber membranes for gas separation, the method comprising: i) a step of mixing a polymer resin, a solvent, and a cosolvent having a boiling point of 80-150°C, and gaining a dope solution; ii) a step of providing and discharging the dope solution to a dual spinning nozzle of a spinneret and forming hollow fibers; and iii) a step of externally coagulating and winding the hollow fibers formed in the step ii) and manufacturing hollow fiber membranes. The asymmetric hollow fiber membranes for gas separation prepared by the hybrid phase separation improves gas permeability constant and selectivity and has excellent mechanical properties, thereby selectively separating one gas from two or more gas mixtures selected from the group consisting of oxygen, nitrogen, carbon dioxide, hydrogen, and methane.
