The invention provides an online monitoring method and monitoring system for margin improvement of nuclear power unit thermal power, wherein the monitoring method comprises the steps: building a real-time database, collecting real-time data of unit output related characteristic parameters, and storing the real-time data in the real-time database; calculating the difference value, the maximum value, the mean value, the sliding mean value and the overtime duration of the characteristic parameters according to the real-time database; comparing the real-time data and the calculated values of the characteristic parameters with corresponding alarm limit values, and judging whether the real-time data and the calculated values exceed the corresponding alarm limit values or not; and if the real-time data and the calculated values exceed the corresponding alarm limit values, triggering an early warning function to give an alarm. The real-time data of the characteristic parameters and the difference value, the maximum v
