With the proposal of the Digital China strategy, high-density cities are accelerating the digital construction of green infrastructure and park management services. The governance scenarios and evaluation index in domestic and international digital parks are studied. Based on the collection, governance, and application processes in data management, a digital park governance assessment system with 48 indexes is constructed, including four dimensions: perception, management, interaction, and wisdom. Then calculate the weight of indexes at each level through expert scoring. According to the construction situation of the digital park, a dynamic assessment method suitable for the different development stages of digital parks is proposed. It makes a preliminary empirical evaluation combined with the typical parks in Shanghai, which provides a reference for understanding the construction of digital parks and optimizing the planning and design of digital parks.
