The effects of nuclear surface dynamics on both fusion and multinucleon transfer reactions are investigated simultaneously within the framework of the improved quantum molecular dynamics model. The capture processes of ${}^{40}\mathrm{Ca}+{}^{40}\mathrm{Ca}$ and ${}^{40}\mathrm{Ar}+{}^{208}\mathrm{Pb}$ systems are simulated using different surface energy coefficients. It is found that a larger surface energy coefficient reduces the Coulomb barrier height, thereby enhancing the capture cross section. For the multinucleon transfer reactions of ${}^{58}\mathrm{Ni}+{}^{208}\mathrm{Pb}$ and ${}^{64}\mathrm{Ni}+{}^{208}\mathrm{Pb}$, we find that a strong surface energy significantly inhibits isospin diffusion processes between the collision partners and reduces the probability of fusion-fission events. Furthermore, an enhanced surface energy extends the lifetime of the dinuclear system, resulting in larger deflection angles for projectile-like fragments in deep-inelastic collisions.
