The invention discloses a shale fracture slippage analysis method and system, and the method comprises the steps: constructing a fracture slippage force calculation formula according to three-dimensional ground stress, fracture geometric characteristics and a friction coefficient; according to a fracture slippage force calculation formula, constructing a fracture slippage theoretical analysis simplified model; analyzing the simplified model for the theoretical analysis of the fracture slippage, and constructing a primary model for the theoretical analysis of the fracture slippage; and the simplified model for theoretical analysis of the fracture slippage constructs an analysis standard for the fracture slippage of the shale in the target area in combination with the geometrical characteristics of the fracture in the target area and the value characteristics of the friction coefficient of the shale. The problem that shale reservoir fracture slippage evaluation lacks theoretical support is solved, a fracture sl
