It is clear that urban green spaces provide numerous health, social, and ecological benefits. However, without adequate preventative measures in place, the environmental benefits provided by these projects such as parks, trails, and better accessibility often lead to a rise in property values and significantly higher housing expenses contributing to green gentrification. This paper studies the factors of green gentrification and provides suggestions for solution and strategies to prevent the problems caused by green gentrification. Results show that characteristics of green space and cities’ geography and development are the main factors of green gentrification. This study focuses on the role of the function, scale of green space and park premium and geographical location in terms of characteristics of green space and distance from the city center, population change, economic growth, and city size in terms of cities’ geography and development context. To alleviate the problem caused by gentrification (such as financial pressure, social conflict, and increasing psychological costs), strategies including “just green enough”, multi-stakeholder participation, and fair benefit distribution system can be taken.
