This research explores the spatial justice issues in China's green transition in the context of global climate change and the growing environmental crisis. Green transition involves energy structure adjustment, industrial upgrading and fair distribution of social resources, and is an important way to achieve sustainable development. However, in the process of green transition, the unbalanced and insufficient development between urban and rural areas and regions has become an important factor constraining China's green transition, especially in the areas of resource allocation, fair participation and environmental protection. This paper constructs a spatial justice evaluation system to assess the spatial equity in the process of green transformation in Guangdong Province.
