Highway access and the critical distance to an industrial location: a survival analysis

摘要

The role of transport infrastructure in regional economic growth has recently attracted a number of researches from a wide range of research fields. This study is aimed to investigate the geographical range of the positive impact of transport infrastructure in terms of the distribution of new industrial locations. The result indicates that there is the critical distance between highway interchanges and plant locations, where a fixed share of new plant locations are distributed. An application of survival analysis revealed that 50% of new manufacturing plants are distributed with a 5 km radius to highway interchanges in recent years. And, only 10% of new plants can survive, when the distance to highway become longer than 20 km.
