The invention provides a combined heat and power generation regional heating production system combined with a heat pump system and a control method of the combined heat and power generation regionalheating production system. The system comprises a steam turbine, a regional heating heat exchanger and a hot water driving type absorption heat pump. The hot water driving type absorption heat pump comprises an evaporator, an absorber, a generator, a condenser and two regional heating water flow adjusting devices. According to the system, the heat pump system and an original combined heat and power generation system can be completely combined through the control system, and power generation output, regional heating flow and regional heating supply temperature of the combined heat and power generation system can be stably maintained; Moreover, due to the fact that exhaust gas moisture condensation latent heat serving as low-temperature heat energy, device cooling heat, heat release in the transformation process, fuel cell cooling heat and the like can be recovered, extra electric power or high-temperature steam does not need to be consumed in the process, and therefore power generationefficiency and heat recovery efficiency can be improved to the maximum extent.
