To be connected or not to be connected? The role of long-haul economies
研究地方接入交通网络（如高铁）后就业是增加还是减少，发现长途经济（边际运输成本随距离递减）是关键因素，并以日本新干线为例，显示中间站点城市就业显著下降。
Abstract We investigate whether localities gain or lose employment when there are connected to a transportation network, such as a high-speed railway line. We argue that long-haul economies—implying that the marginal transportation cost decreases with network distance—play a pivotal role in understanding the location choices of firms. We develop a new spatial model to show that improvements in transportation infrastructure have nontrivial impacts on the location choices of firms. Using data on Japan’s Shinkansen, we show that ‘in-between’ municipalities that are connected to the Shinkansen witness a sizable decrease in employment.
