The invention relates to a geometric configuration optimization design method for a resonant buoyancy pendulum type wave energy power generation device. The optimization target is to improve the natural vibration frequency adjusting capacity and the energy harvesting capacity of the resonant buoyancy pendulum type wave energy power generation device in an arrangement sea area. According to the method, a large number of geometric configuration cases of different pendulum body side profiles, balancing weight side profiles, rotation center positions and pendulum body submerging depths are randomly set, hydrodynamic parameters in the pitching direction are obtained, frequency domain calculation is implemented, a natural vibration frequency-balancing weight position curve and a capture width ratio-natural vibration frequency curve are drawn, and the natural vibration frequency-balancing weight position curve and the capture width ratio-natural vibration frequency curve are calculated. And finally, based on the wav
