The invention relates to a GEO satellite east-west control quantity optimization selection method. The method comprises the following steps: 1) forecasting a current orbit; 2) calculating an input quantity of an east-west controlled quantity analytical solution; 3) calculating an analytic solution of east-west control quantity; 4) iteratively correcting the control quantity by a numerical method; and 5) determining the control quantity considering the control error. According to the method, a formula for solving an east-west control quantity initial value through an analytical solution is deduced, a method for iterative optimization through a numerical method is designed, a control quantity optimization model for solving the initial value through the analytical method and iterative optimization through the numerical method is established, the problem that calculation precision and calculation speed are difficult to consider at the same time is solved, and the method can be applied to GEO satellite east-west c
