Abstract: Joint inversion on geodesy and geophysics, which integrates geodetic observations with geophysical modeling, has emerged as a powerful interdisciplinary approach for investigating Earth system processes. We present a comprehensive review of its conceptual framework, core principles, and research scope along three main dimensions. A historical overview traces the evolution of this paradigm in both international and domestic research contexts. The review focuses on three representative application areas: seismic source parameters inversion, kinematic rupture process modeling, and reconstruction of crustal deformation velocity fields. Key methodological challenges are identified, including issues related to data heterogeneity, model coupling, and uncertainty quantification. Strategies for advancing integrated inversion techniques are proposed, with an emphasis on fostering synergies between geodetic precision and geophysical modeling. This work also highlights the potential of joint inversion on geodesy and geophysics to support national strategic needs in natural hazard mitigation and geodynamic monitoring, and its critical role in the development of next-generation Earth observation systems.
