Density Policies in Various Countries/Cities
In order to determine the spatiotemporal obstacles in public-private redevelopment within Hong Kong's urban renewal, and to identify potential solutions for density schemes under various floor area ratio (FAR) regulations, this study first conducted international comparative case studies. These focused on changes in FAR regulation programs and related activities as a way to gain insights into how FAR regulations interact with urban land market dynamics and planning processes over time.
density policies in various countries/cities in terms of general implication, partial implication, and exceptions

(a) Heritage protection; (b) Environmental protection; (c) Affordable housing; (d) Urban public facility; (e) Farmland protection; (f) Transportation facilities
Potential Density Schemes
Further incorporating existing policies, legislation, and practices in Hong Kong, this study identifies the obstacles in public–private redevelopment in Hong Kong’s urban renewal process and proposes latent density schemes in Hong Kong, laying a solid foundation for detailed model development and counterfactual analysis
Offering additional floor area ratio (FAR) or plot ratio
Allowing the development of commercial facilities in an area originally designated for residential construction
Allowing for the demolition and reconstruction of a building on its original site, while transferring a portion of the development density (which could refer to the floor area or the number of storeys) to an undeveloped plot within the city
A decayed residential building is demolished and reconstructed on-site, while the unused developmental density from the original structure can be transferred to another location, with this transfer being monetized
Allowing the reservation of unused development density for future usage
