Abstract: Public green spaces (PGSs) play a positive role in urban social sustainability and solidarity, as all urban dwellers can access them without discrimination or restrictions, but urbanization usually leads to an extreme shortage of PGSs and thus it becomes an important spatial resource that is competed for by different groups, especially migrant populations. Taking the Macau Peninsula as an example, this study employed a hybrid analysis approach, including the spatial Gini coefficient, spatial share index and spatial quality assessment, to look at the PGS injustice in high-density post-colonial areas. The results showed that (1) there is a “spatial mismatch” in the Peninsula’s PGS; (2) significant PGS service differences have been found between the colonial group (Portuguese) and immigrant group (Southeast Asian); and (3) a comparative analysis of the changes in the equity of PGSs over the past 40 years reveals that the PGS tends to be equitable overall, but the differences between groups have gradually increased. PGS injustice mainly depends on the spatial production mechanism during the colonial period of Macau and the spatial selection and limitation of groups due to differential social integration. Based on this, this work proposes recommendations for the planning and construction of PGS in terms of urban renewal and social sustainability, as well as new reclamation areas, in Macau. This study broadens the field and helps to improve the PGS inequality in high-density post-colonial areas, aiding regional sustainable development.
