In recent years, many entities such as power grid utilities, power producer and heating companies have been widely involved in the field of integrated energy services（IES）. A competitive landscape in which different interests of different stakeholders are coupled with each other is formed. It is urgent to achieve healthy development under the guidance of multiple factors such as technology, market and policy. Therefore, clarfying the stakeholders involved in the park level IES, and the characteristics is of great importance to each stakeholder, participation enthusiasm, internal driving force, and the interest coupling relationship between different stakeholders. The main stakeholders of the park level IES is sorted out, and the demand for integrated energy services in different park scenarios is analyzed. The interest demands and participation methods of various stakeholders are summarized. The coupling relationship of various stakeholders in IES from the competition of power supply and heating is studied. The cooperation and competition relationship among the various stakeholders in the industrial and commercial scenario is obtained. Finally, the overall interest pattern of park level IES is proposed.
