ABSTRACT=<p>The flux-weighted average cross sections and isomeric ratios of <sup>92</sup>Mo(<italic>γ</italic>, n)<sup><italic>91m,g</italic></sup>Mo and <sup>92</sup>Mo(<italic>γ</italic>, 3n)<sup>89</sup>Mo reactions were measured through activation methods. Laser-driven bremsstrahlung <italic>γ</italic>-ray were generated by the laser wakefield accelerated quasi-monoenergetic electrons using the 200 TW laser in the Compact Laser Plasma Accelerator laboratory, Peking University. The results showed good agreements with previous works using traditional <italic>γ</italic>-ray sources, and were compared with TALYS 1.9 calculations. We extended the experimental results of <sup>92</sup>Mo photonuclear reactions to higher energies, the experimental discrepancies of <sup>92</sup>Mo(<italic>γ</italic>, n)<sup><italic>91m,g</italic></sup>Mo isomeric ratios at high energy region were clarified, and the cross sections of <sup>92</sup>Mo(<italic>γ</italic>, 3n)<sup>89</sup>Mo reaction were first obtained.</p>
