In the process of urbanization and globalization, urban conservation reinforces the links among past, present, and future, which enhances local identity and is indispensable for urban sustainability. The concept of Historic Urban Landscape (HUL), as both a notion and an approach, has been playing an increasingly important role in urban conservation discourse. Prioritizing actions is one of the pivotal procedures to perform the HUL approach. Instead of simply focusing on values selected and graded by experts, more attention should be paid to local residents' satisfaction. A collaborative approach involving communities to prioritize actions in urban conservation and regeneration is proposed. Using the data from residents in the old town of Dandong, China, this study pioneers the application of the Asymmetric Impact-Performance Analysis (AIPA) technique in the urban conservation field. HUL attributes are categorized into basic factors, excitement factors, and performance factors based on their potential asymmetric impact on residents' satisfaction. By taking performance levels of the attributes into consideration, this study further identifies improvement priorities for HUL, which helps planners and city managers to make rational choices in managing historic cities.As the link between history and present, urban heritage is an integral component of local identity. Urban heritages together with the memories and associations inherent in them are the evidence that addresses how urban landscape has been continuously shaped and changed [4]. Both tangible and intangible urban heritage are precious and have the potential to be drivers of social cohesion and urban regeneration [5].Urban conservation has been a focus in urban planning, architecture, and other related fields since it was developed after the French Revolution [2]. Along with the evolution of this idea, the motivations for conservation have been changing over time. Urban conservation has gone through "Antiquarian Bias", "Commemorative Bias", and "Aesthetic Bias" in both academia and practice during the past three centuries, while a new bias is emerging in the 21st century which focuses on the relationships between different things, as well as between things and people, rather than things themselves [6]. This current trend is to see the human environment as a cultural landscape with an intention to manage it within the landscape discourse, which is called "Ecological Bias". From this holistic view, urban conservation and urban development are no longer incompatible with each other, since their joint aim is to enhance the human environment and allow communities to prosper. It has become increasingly clear that urban conservation is a key resource and an indispensable part of urban sustainability [7].The culmination of this new trend came in 2011 when Recommendation on the Historic Urban Landscape was declared [1] and commonly accepted. The concept of Historic Urban Landscape (HUL) was first set out at a UNESCO conference in Vienna in 2005 [8], thus HUL, as a new a...
