内容简介:
       This paper studies the effect of transport infrastructure on inventory using firm level data combined with road information. Different from previous studies, we measure a firm’s accessible transport infrastructure using road area of both local and neighboring cities and focus on the transmission channels through which transport infrastructure affects inventory. Our theoretical framework highlights that under demand uncertainty, roads affect inventory through market expansion and reduction in sourcing cost of input. The two transmission channels are also confirmed in our empirical evidence. This paper enhances the literature by providing a comprehensive framework for analyzing the relationship between transport infrastructure and inventory and more importantly, on estimating the causal effect of infrastructure on economic scale and efficiency.
