Abstract

Based on provincial panel data observed over the 2005–2014 period, we analyze the impacts of transportation infrastructure investments on inventory levels in China’s manufacturing sector. Our results indicate that transportation infrastructure investments do not reduce inventory levels in the manufacturing sector in China. This conclusion is different from the results in the previous literature, which demonstrate positive effects of transportation investments on reducing inventory levels. The difference can be partly explained by the ongoing inland shift of industry and geographic market expansion in China, which lead to longer transportation distances and longer lead times from suppliers to customers. We also find that road investments have spatial spillover effects overall, and the impacts of different types of road investments differ significantly from each other. Railway investments, however, do not have spatial spillover effects. Finally, we present several policy implications of transportation infrastructure investments, inland shifts of industry, and geographic market expansion.

交通基础设施投资是否降低了中国制造业的库存水平？

基于2005-2014年各省面板数据，我们分析了交通基础设施投资对中国制造业库存水平的影响。我们的研究结果表明，交通基础设施投资并没有降低中国制造业的库存水平。这一结论不同于以往文献的结果，证明了运输投资对降低库存水平的积极影响。造成这种差异的部分原因是中国正在进行的工业内陆转移和地域市场扩张，这导致从供应商到客户的运输距离更长，交货时间更长。研究还发现，道路投资总体上具有空间溢出效应，不同类型道路投资对空间溢出效应的影响存在显著差异。然而，铁路投资不具有空间溢出效应。最后，我们提出了交通基础设施投资、产业向内陆转移和地域市场扩张的若干政策含义。

期刊介绍： International Regional Science Review serves as an international forum for economists, geographers, planners, and other social scientists to share important research findings and methodological breakthroughs. The journal serves as a catalyst for improving spatial and regional analysis within the social sciences and stimulating communication among the disciplines. IRSR deliberately helps define regional science by publishing key interdisciplinary survey articles that summarize and evaluate previous research and identify fruitful research directions. Focusing on issues of theory, method, and public policy where the spatial or regional dimension is central, IRSR strives to promote useful scholarly research that is securely tied to the real world.
