지하철 및 고용접근성 변화가 서울시 고용중심지의 고용밀도 변화에 미치는 영향

Abstract

We examined the effects of the improvement of the subway system and changes in job accessibility on changes in employment density of employment centers in Seoul between 2000 and 2010. To do so, we first explored where the employment centers are in Seoul, and measured job accessibility considering the effects of supply and demand. Then, we investigated how the improvement of the subway system and changes in job accessibility affect changes in employment density in Seoul. Our findings showed that (1) employment sub-centers have increased and spread near the existing employment centers; (2) CBD, except for Junggu, has declined continuously during the past 10 years; (3) job accessibility has been improved, which affected employment growth; (4) improvement of the subway system in Seoul influenced an increase in employment density; and (5) information and technology industry has grown, whereas manufacturing industry has declined in Seoul. The results suggest important policy implications that (1) declined employment centers should be managed by comprehensive plans such as urban regeneration strategies and (2) it is necessary to make a plan to improve job accessibility in Seoul.
