| Abstract: | Over the past few years, a large number of studies have focused on whether population or employment is critical to the source of metropolitan growth. However, only few attempts have so far been made to additionally consider the suburbanization stage and pattern of commuting, which may both enable us to explore this “chicken–egg” issue a little further. The purpose of this paper is to compare dwelling‐based (housing) with job‐based (job) employment to evaluate the net commuting. The Taipei metropolitan area, for example, now lies at the initial suburbanization stage with only population decentralization and massive in‐commuting to the central city. The estimation results based on a co‐integration system reveal that the central‐city employment can be regarded as an engine of this metropolitan economy. Besides, we also find that dwelling‐based employment distorts the causality between population and employment, especially from the variance‐decomposition accounts. Therefore, the importance of commuting to investigating the evolution of metropolitan economy should not be overlooked. |
