Exploring the Key Factors Influencing Commercial Land Use Decisions in Port Harcourt

Abstract

Commercial land use expansion has become a defining feature of rapidly urbanizing cities in Nigeria, often reshaping residential neighbourhoods and altering urban spatial structure. Despite this transformation, limited empirical research has examined the key determinants influencing commercial land use decisions at corridor level in Port Harcourt. This study investigates the factors influencing commercial land use decisions along Woji Road (GRA Phase 2) and Peter Odili Road in Port Harcourt, Rivers State. A mixed-methods approach was adopted, combining field observation and structured questionnaires administered to 184 business and property owners selected through systematic sampling. Data were analysed using Chi-square statistics, Shannon–Wiener Diversity Index, and multiple response analysis. Results show statistically significant differences in land-use distribution (χ² = 25.490, p < 0.05) and commercial activity composition (χ² = 33.94, p < 0.001) between the two corridors. Shannon diversity values indicate higher commercial diversity along Peter Odili Road (H′ = 0.997) compared to Woji Road (H′ = 0.386). Location (97.8%) and economic considerations (92.9%) emerged as dominant drivers of commercial land use decisions, while agglomeration effects (10.4%) and legal factors (30.4%) were comparatively weaker determinants. The findings highlight the primacy of accessibility and market-driven forces over regulatory and clustering considerations in shaping commercial land use decisions. The study provides empirical insight for urban planning policy, particularly in strengthening zoning control, managing corridor commercialization, and promoting sustainable spatial development.
