4.2.2 The Seven-Variable Structural Framework

The Dual-Scale Variable Structure (DSVS) provides the organizational framework of the Urban Value Field. However, describing spatial hierarchy alone is insufficient for quantitative analysis. To transform the structural organization of urban space into a measurable scientific model, DSVS introduces a unified Seven-Variable Structural Framework.

The framework represents the intrinsic characteristics of every urban location through seven fundamental structural variables. Rather than acting independently, these variables collectively describe the spatial capacity of a location to generate, receive, and sustain urban value.

The seven variables are selected to satisfy four fundamental requirements:

• Structural completeness, ensuring that the major components influencing urban value are represented.

• Spatial measurability, allowing each variable to be derived from observable spatial data.

• Computational consistency, enabling mathematical integration within the Urban Land Value Framework.

• Scalability, supporting analyses across different spatial levels, from individual parcels to metropolitan regions.

Unlike traditional land valuation factors, the seven variables are not treated as isolated explanatory variables. Instead, they form an integrated structural system in which each variable interacts with the others to characterize the intrinsic spatial condition of a location.

Within DSVS, the seven-variable framework serves as the quantitative representation of the structural organization of the Urban Value Field. It establishes the structural foundation upon which subsequent computational models, including the Value Creation Model (VCM) and the Value Radiation Model (VRM), are constructed.

Consequently, the seven-variable framework functions as the mathematical interface between urban spatial structure and value generation.
