This research project, based on the hot issues of escaping from mega cities in China, focuses on young graduates and intends to improve their livability and make Shenzhen a more migrant-friendly city to them. Livability, including affordability and good accessibility to services and jobs, is the main topic and final goal of this thesis. To reach this goal, urban form study, which is the study of urban environments through the physical form, is put forward. Through the understanding of the context of livability, urban form and the relationship between livability and urban form, this thesis explores the current urban forms in Shenzhen and the possible ways to transform it by the change of function and density to improve livability and get jobs-housing balance.
