This study empirically examines the price spillover effects of price changes in reconstructed apartments from five major redevelopment districts (Geumjeong-gu, Nam-gu, Dongnae-gu, Buk-gu, and Suyeong-gu) in Busan, South Korea, on the prices of general apartments across four regional clusters (East, West, South, and North). In recent years, reconstruction projects in Busan have significantly influenced local real estate markets, raising concerns over how far redevelopment-induced price shocks propagate redevelopment-induced price shocks propagate locally and across different regions within the city. To systematically address this, the current research investigates how price shocks from redevelopment areas affect not only nearby districts but also geographically distant areas.
Monthly apartment sales price data from 16 general districts and five reconstruction districts in Busan were analyzed using several econometric methods. The analysis included unit root tests, Granger causality tests, and a vector error correction model to clearly identify the pathways and intensity of price spillover effects. Additionally, impulse response functions and forecast error variance decomposition were applied to further quantify and elucidate the characteristics of regional price spillover effect.
The results indicate that price shocks from reconstruction apartments in Suyeong-gu significantly and positively influence general apartment prices in both the South and East regions, particularly showing strong spillover within affluent districts such as Suyeong-gu and Haeundae-gu. Similarly, reconstruction price shocks in Geumjeong-gu and Dongnae-gu exert a noticeable influence on general apartment prices in the North and East regions, emphasizing the role of geographic proximity and residential connectivity as key determinants of price spillover. Nam-gu played a pivotal role in price interactions between the South and West regions, serving as a critical spillover channel between these clusters. Conversely, price shocks from Buk-gu displayed significant but largely localized effects within its own regional cluster, showing comparatively limited price spillover effects to other regions.
These findings underscore the differential nature of price spillover effects across Busan's regions, emphasizing that redevelopment-driven price movements are closely tied to localized and geographical contexts. This study highlights the necessity for policymakers to consider these distinct regional spillover dynamics when formulating reconstruction and housing policies. Future research could incorporate additional regional characteristics and more sophisticated econometric techniques to deepen the understanding of price dynamics in urban redevelopment markets.
