In this paper, we consider the continuous time dynamic optimal asset allocation problem under the stochastic interest rate. We suppose that the market interest rate satisfies a stochastic process with the characteristic of mean-reverting, and the financial market consists of a zero-coupon bond and two dependent risky assets whose prices are suffered a common shock. Under the mean-variance criterion, using stochastic optimal control theory and Lagrange dual principle, the analytical solution for the efficient investment strategies and corresponding efficient frontier are obtained. Finally, through numerical examples, the sensitivity of efficient strategies and efficient frontier to relevant parameters are analyzed, and the relevant theoretical results are also verified.
