The invention discloses a PPG waveform-based hybrid continuous blood pressure measurement model construction method and a measurement system. The PPG waveform-based hybrid continuous blood pressure measurement model construction method comprises the following steps: step 1, collecting PPG signals of a measured object and a corresponding reference blood pressure value; 2, according to the collectedPPG signals, preprocessing and calculating to obtain corresponding PPG characteristic parameters; 3, respectively establishing an individualized model and a universal model for blood pressure prediction; wherein the individualized model is divided into an individualized no-dicrotic-wave parameter model and an individualized full-characteristic parameter model; 4, mixing the individualized model and a universal model to establish a hybrid model; and step 5, measuring the PPG signal of any testee, inputting the PPG signal into the hybrid model established in the step 4, and continuously obtaining the blood pressure val
