The ambiguous value orientation of residential land development intensity in current regulatory planning compilation in China results in lack of public interest and lack of scientific bases for determining indicators. To address these problems, this paper explores the internal logic between the essence of regulatory planning and the development intensity index system compilation in current social context. Then taking the residential plot(neighborhood) as an example, the paper selects public interest factors that are closely related to development intensity, including per capita concentrated green space, parking spaces, and sunlight spacing, and obtains a three-level indicator system: "rigid bottom line – elastic interval – modification indicators" based on the original index system. Furthermore, it defines the attribute of indicators, to ensure a mandatory, open, and guiding indicator system. Finally, it builds a development intensity indicator system with public interest factor as its core, in order to balance the equity and efficiency in the process of regulatory planning compilation, and to promote the scientificity of the compilation method.
