Research title: The effect of highway infrastructure on firms' inventory and fixed investment in China

Research Summary

Yanyu's research interests include corporate finance, green finance, transportation economics, and development economics.  Her current research focuses on the effects of highway construction on manufacturing firms' inventory and investment decisions and capital allocation efficiency. 

Working paper:

The Effect of Highway Access on Firms’ Inventory Investment in China

Abstract:  This paper examines the causal effect of highway access on firms’ inventory investment, using a geo-coded firm-level panel dataset for Chinese manufacturing firms in the period 1998-2007. Two types of endogeneity concerns arising from the non-random distribution of highways and the endogenous location of firms are addressed using various instruments and samples. Our results show that better access to highways encourages firms to reduce their input and total inventories. Each dollar of highway spending in China reduces the input inventory stock by about 3.9-10.0 cents and the total inventory stock by around 6.7-25.5 cents. Firms’ input inventories are more affected by highways through the direct channel of reduction in transportation cost and transit time, whereas firms’ output inventories are more affected by the demand channel. We find that the cost-saving benefits of input inventories are unevenly distributed across firms, sectors and regions.

The Effect of Highway Accessibility on Corporate Investment in China

Abstract: This paper investigates whether and how highway accessibility affects corporate investment using a geo-coded micro-level panel dataset for Chinese manufacturing firms. To identify the causal effect, we construct three sets of instruments for highway variables, that is, the least cost paths, straight line network and historical courier routes. We find that better access to highways promotes firms' investment, supporting the crowding-in effect of public investment. Since firms may have endogenous location choices, the endogeneity problem is further controlled by including only those firms that have existed since 1999 and have never switched locations. Highway proximity is found to stimulate corporate investment through at least three mechanisms, that is, by reducing firms' financial constraints, releasing additional internal funds via inventory reduction, and mitigating the negative impact of uncertainties. Our results are robust when different highway measures and instruments are adopted.
