The present invention relates to a technique for improving the productivity of L-arginine, specifically an L-arginine producting strain inducing the expression of cgR_2827 by introducing polynucleotide coding cgR_2827 polypeptide, and a production method of L-arginine using the strain. By the present invention, the fermentation yield of L-arginine is improved, and a practical effect for solving the short supply of L-arginine throughout the world is provided. The L-arginine can be applied to medicines, food, animal feed, and other products for increasing the demand, and can provide a positive effect industrially.
