An embodiment of the invention provides a pointer analysis method and device. The pointer analysis method includes the steps: reading statement information in a multi-thread procedure to be analyzed; analyzing the pointer of the procedure according to the statement information of the procedure to obtain share information; performing compensation analysis for the share quantity according to the share information of the procedure. The share information comprises the share quantity, a pointer pointing set and a memory access behavior, and the share quantity includes global share quantity and local share quantity. The method solves the problems that analysis of the pointer of the multi-thread procedure is limited in global share quantity in the procedure and analysis results are incomplete in the prior art, analysis accuracy of the pointer is improved, and optimizing implementation ranges and optimizing effects of the procedure are correspondingly improved.
