In this paper, we first consider global well-posedness and long time behavior of compressible Navier-Stokes equations with Yukawa-type potential in $L^p$-framework under the stability condition $P'(\bar\rho)+\gamma\bar\rho>0$. Here $\bar\rho>0$ is the background density, P is the pressure and $\gamma\in\mathbb{ R}$ is Yukawa coefficient. This is a continuity work of Chikami \cite{ chikami1} concerning on local existence and blow-up criterion. On the other hand, we study the instability of the linear and nonlinear problem of the system when $P'(\bar\rho)+\gamma\bar\rho<0$ in the Hadamard sense.
