ECONOMIC IMPACTS OF SEOUL'S JOB DECENTRALIZATION: A METROPOLITAN INPUT–OUTPUT ANALYSIS
利用首尔大都市投入产出模型，分析就业分散化对首尔大都市区的经济影响，发现无论就业扩张发生在何处，该区域都能获得显著经济收益，且就业分散化通过生产、收入形成和消费的良性循环产生正向诱导效应。
ABSTRACT This study analyzes the economic impacts of job decentralization with the aid of the Seoul metropolitan input–output model (SMIO) for the Seoul Metropolitan Area (SMA). Two main features can be highlighted: modeling perspective and simulation results. The SMIO is a pioneering work in the application of this type of metropolitan input–output analysis to the real world by taking into account the spatial and industrial relationships of multiplier effects simultaneously within a metropolitan economic system. The simulation results show that job decentralization results in a serious spatial and industrial restructuring of the metropolitan economy, and that the SMA gains significant economic benefits from job decentralization, no matter where the job expansion takes place within the metropolitan region. Interesting to find is that job decentralization generates positive induced effects for all scenarios through a virtuous circle of production, income formation, and consumption, given suburbanized population, which is one of the economic reasons why jobs follow people.
