The present invention relates to a method for producing modified cellulose fibers having cellulose I crystal structure, comprising: step A: introducing Substituent Group A to cellulose fibers via an ether bond in a solvent comprising water in the presence of a base, and step B: introducing Substituent Group B to cellulose fibers via an ether bond in a solvent comprising water in the presence of a base, wherein the method includes the steps A and B concurrently, or in the order of the step A and then the step B. The cellulose fibers of the present invention obtained by the method for production of the present invention have favorable dispersibility in a hydrophobic medium and a controlled increase in viscosity.
