这项研究考察了集聚对区域生产率的好处，并利用日本的经验数据突出了可获得性问题。本文采用计量经济学方法，假设了三种集聚经济类型：城市化集聚、地方化集聚和混合集聚，实证分析了集聚对区域经济收益的影响。我们使用1981年、1986年、1991年、1996年、2001年和2006年的区域交通网络数据和区域社会经济面板数据估计了11个行业的集聚弹性，覆盖了日本的47个县。研究结果表明，平均而言，地方性集聚对区域生产率提高的间接效益往往比城市化集聚的间接收益更显著。矿业受益于城市化而非地方化集聚，交通/通信业受益于地方化而非城镇化集聚，金融/保险和房地产业可以从这两个集聚经济中受益。我们进一步发现农业和服务业存在负弹性；这可能部分是由于这些行业的特点造成的。日本的案例研究表明，土地利用和交通投资之间的协调对于通过集聚实现区域生产率最大化具有重要意义。
This study investigates the benefit of agglomeration to regional productivity, highlighting the issue of accessibility with empirical data from Japan. We analyze empirically the impacts of agglomeration on regional economic return using an econometric approach, assuming three types of agglomeration economics: urbanization agglomeration, localization agglomeration, and mixed agglomeration. We estimate the agglomeration elasticities of 11 industries using inter-regional transportation network data and regional socioeconomic panel data for 1981, 1986, 1991, 1996, 2001, and 2006, covering 47 prefectures in Japan. Our results show that, on average, the indirect benefit of regional productivity improvement from localization agglomeration tends to be more significant than that from urbanization agglomeration. While the mining industry enjoys significant benefit from urbanization rather than localization agglomeration and the transportation/communication industry enjoys significant benefit from localization rather than urbanization agglomeration, finance/insurance and real estate can benefit from both agglomeration economies. We further find negative elasticities in the agriculture and service industries; this could be partly due to the industries’ characteristics. A case study on Japan shows the importance of coordination between land-use and transportation investment for maximizing regional productivity through agglomeration.
