Provided are a recombinant human interleukin-11 mutant, and a conjugate of the mutant conjugated to a chemical molecule and a use thereof. The recombinant human interleukin-11 mutant achieves soluble expression in an Escherichia coli expression system by means of an SUMO sequence tandem fusion method. The conjugate is obtained by the site-specific conjugation of the mutant to the chemical molecule at a mutant amino acid residue in position W147 by means of a covalent bond. The chemical molecule is at least one of polyethylene glycol, an alkanoic acid aliphatic chain, and a hydrophilic high-molecular polymer containing an alkanoic acid aliphatic chain.
