The author studies the concentration rate of the total mass for radially symmetric blow-up solutions to the Cauchy problem of a degenerate drift-diffusion system with the mass critical exponent. After summarizing some known results on the existence and some properties of weak solutions, the author gives the \(L^1\)-concentration rate, which improves the corresponding known results.
