PROBLEM TO BE SOLVED: To provide a dry-wet spinning method by which a spinning speed is heightened to improve the productivity, and a fiber having little dispersion of quality among single fibers constituting a yarn, and stable properties is obtained while suppressing the occurrence of single fiber breakage; and to provide an apparatus therefor. SOLUTION: The dry-wet spinning method comprises spinning a spinning dope (D) from a spinning cap (1) having many spinning holes bored therein into a gaseous body, introducing the spun dope (D) into a coagulation liquid (La) flowing down in a flow tube (3) to coagulate the dope and to form the fiber, and taking up the fiberized yarn (Y), wherein a coagulation liquid (Lb) having a different solvent concentration contained in the coagulation liquid is injected to the midway of the flow tube (3), and the speed, the flow rate, the concentration and/or the temperature of the coagulation liquid flowing down in the flow tube (3) are regulated.
