With the increasing demand for energy service diversity and the rapid development of clean energy, the development of integrated energy services (IES) that meet the needs of diverse energy production and consumption has become a key area widely concerned by energy and power companies. There are many stakeholders in the park level IES. To guide the healthy development of IES, it is urgent to evaluate the enthusiasm and contribution of the stakeholders involved in the IES operation. By establishing an index system and combining subjective and objective analysis methods, the enthusiasm and contribution of stakeholders to participate in the operation of IES is evaluated. Finally, an empirical analysis is made by taking the southern compound green energy network in Jiangsu Province as an example.
