Quantitative analysis for high harmonic generation (HHG) based on the quantum trajectory perspective is suggested for CO molecules. We show that the central Bohmian trajectories define the right structure of high harmonic spectra while others, including the outermost trajectories, contribute nonlocally to the HHG intensity. This technique based on counting the number of returning events differs from the three-step model and is useful for explaining the multi-electron effects such as the dynamic core-electron polarization.
