The embodiment of the invention discloses a target code rate control method and an electronic device. The method comprises the following steps: calculating a target code rate of a current frame in a video stream (the formula is described in the specification), allocating a target code rate ratio Tlayer_N to a target layer encoding structure, and controlling the target code rate (the formula is described in the specification) of the current frame through the target code rate ratio Tlayer_N to obtain a controlled target code rate Ri of the current frame. By adoption of the method of the embodiment, different target code rate ratios Tlayer_N can be allocated to different target layer encoding structures according to the video characteristics, thereby flexibly allocating different target coderates Ri of the current frame to the different target layer encoding structures according to the video characteristics, the target code rate Ri of the current frame can be corrected according to the characteristics of video s
