The invention relates to a method for setting the roll shifting amount of a working roll, and belongs to the technical field of hot continuous rolling methods. According to the technical scheme, the rolling characteristics of a four-high rolling mill and the influence mechanism of the roll shifting amount on the strip steel plate shape are comprehensively considered, and the relation between the set value of the roll shifting amount and parameters such as inlet thickness distribution, outlet thickness distribution and the optimal strip steel plate shape is studied; and establishing a roller shifting amount set value optimization objective function taking the optimal strip shape of the strip steel as an objective, and setting a proper roller shifting amount. The method has the beneficial effects that the optimal strip shape of the strip steel is obtained by setting the proper roll shifting amount, the strip shape control capability of the four-roll mill is improved, and the economic benefit of on-site strip st
