Using county-level data, we analyze the impact of county-level ports infrastructure investment for the state of California. Estimating county-level production functions for the manufacturing and retail trade industries, we include the level of ports infrastructure stocks in own and neighboring counties as shift variables in the production function. As another form of county interdependency, we also test for and find significant evidence of spatial autocorrelation, and we accordingly adapt our model. We find positive impacts from county-level port investment on manufacturing output, while we find mixed spillover effects of port investment in neighboring counties. Counties with large ports experience negative spillovers from increases in neighboring counties ports infrastructure. On the other hand, some counties with smaller ports experience significantly positive spillovers from additional neighboring counties ports infrastructure stocks, while others with smaller ports experience no significant impact from changes in neighbors ports. We find unambiguous positive spillover effects from ports infrastructure on the retail trade sector in adjacent counties.
