Provinces of sending- end grids not only need to balance its internal high growth load and new energy resources, but also meet the demand for the external transmission. Therefore, the lack of adjustment ability of the electricity exporting regions challenges the operation economy and stability. Demand response is an important technology to provide more regulation ability for power systems, which can effectively minor the peak- valley difference and relieve the tension of the power supply. At present, demand response in China has been carried out in many electricity importing regions, but the electricity exporting regions carrying out demand response are still few. Aiming at the above problems, the necessity of demand response in electricity exporting regions is analyzed from four aspects：rapid load growth, a high proportion of new energy generation, the risk of power supply shortage, and inter-provincial power transmission and trading. Suggestions are put forward from three aspects：development path of market supporting mechanism, demand response scheme considering regional characteristics, and emergency demand response planning, which can provide advice and guidance for the development of demand response in electricity exporting regions.
