| Abstract |
In this study, the effects of the construction of Gwangju-Jeonnam Innovation City were examined on the existing urban context around the
city in the respect of urban spatial structure, and improvement directions of the broader region of Gwangju and Naju were discussed.
Focusing on the wide-range region from Gwangju Metropolitan City to Naju City including the innovative city, comparative analyses were
conducted of the wide-range spatial structures before and after construction of the innovative city using Primal Spatial Network-based Spatial
Analysis. As a result, it was found that Gwangju-Jeonnam Innovative City had more influence on Gwangju Metropolitan City, than Naju
City. After construction of the innovative city, Gwangju City showed clear differentiation of accessibility and centrality by region. The
centrality has moved to the southern areas of Gwangsan-gu and Nam-gu, and accessibility has increased on the arterial roads connecting the
innovative city and Gwangju. However, the accessibility of those roads did not spread to urban cores. Rather, it was found that the
accessibility was lowered on the second ring road and the arterial roads connected to it, and the centrality in the urban cores was lowered
than before construction of the innovative city. In this regard, Gwangju Metropolitan City is expected to increase the likelihood of
development in the outskirts of the city, which is a boundary area with Naju, due to the innovative city. While it is expected that the
centrality of the urban cores is shifting, and some urban cores will decline or even become hollow. Moreover, the phenomenon of decline of
the old urban core is more concerned than other regions in that the centrality of the old urban core has already begun to decrease before the
construction of the innovative city. |
