本研究开发了一种估算日本全国真实的经济中地区间资本流动的方法,这对于尽可能详细地了解地区经济非常重要,而现有的人口普查无法充分监测。该方法可以使用企业间交易大数据(IF数据)和人员流动大数据(PF数据)监测三种资本流动的空间分布:企业间交易(F2F)、企业到消费者的工资流动(F2C)和消费者到企业的消费行为流动(C2F)。首先,我们使用IF数据估算了F2F,IF数据报告了公司总部之间的所有资本流动。其次,我们使用移动的手机上的自动GPS功能收集的PF数据来估计所有消费者的家庭、工作地点和消费地点。第三,我们估计每个消费者的F2C估计他们的工资的基础上,在IF数据中的公司的位置。最后,我们通过估算各个消费地点的F2C消费量,来估算各个消费地区的C2F。我们开发了一个数据集,可以监测日本各地的微观资本流动。这项研究是任何国家首次尝试开发一个数据集,可以以非常高的分辨率监测全国资本流动的空间分布和时间序列变化。我们期望我们的数据将有助于制定政策,以解决日本私营部门和地方政府之间的社会经济问题。
This study develops a method to estimate inter-regional capital flows in the real economy across Japan, which is important for understating the regional economy with as much detail as possible, and that existing censuses do not monitor adequately. The method can monitor spatial distributions of three kinds of capital flow: inter-firm transactions (F2F), firm-to-consumer flows as salaries (F2C), and consumer-to-firm flows as consumption behavior (C2F) using inter-firm transaction big data (IF data) and person flow big data (PF data). First, we estimated F2F using IF data that reports all capital flows between a company’s headquarters. Second, we estimate the home, work place, and consumption locations of all consumers using PF data collected by the auto-GPS function on mobile phones. Third, we estimate the F2C of each consumer by estimating their salaries based on the locations of firms in the IF data. Finally, we estimate the C2F of each consumption area by estimating the consumption of F2C in each consumption location. We develop a dataset that can monitor micro-scale capital flows across Japan. This study is one of the first attempts in any country to develop a dataset that can monitor the spatial distribution and time-series changes of nationwide capital flows at a very high-resolution scale. We expected that our data will contribute to policy-making to address the socioeconomic problems in the private sector and among local governments in Japan.
