Market Access and Firm Performance: Evidence Based on GIS Analysis of Road Network and Manufacturing-Plant-Level Data from India
We investigate whether better access to markets through an improved road network plays a role in improving firm profitability in India. We construct a district-level market access index using shapefiles of India's road network, district boundaries, and nightlight raster images and estimate the shortest driving distances for districts using the road network. Using the annual survey of industries data for India during 2001–2015, we show that market access through improved road connectivity resulted in a lower dispersion of ROA between 2001 and 2015 in India.
