Study insights:
- Business activity rises in port municipalities, with business tax revenues increasing by about 17% after joining the RoRo network
- Neighboring municipalities experience an average 6.5% decline in local income as economic activity shifts toward transport hubs
- Host municipalities show no significant overall income gains, suggesting redistribution—not expansion—of economic activity

Improved transport connectivity through the Philippines’ Roll-on/Roll-off (RoRo) network boosts business in port municipalities—but nearby towns lose income as activity concentrates in transport hubs.
A study by the òòò½´«Ã½, titled “,” finds that municipalities near RoRo ports experience a 6.5% decline in income after nearby ports become operational.
Authored by Senior Research Fellow Kris Francisco and former Senior Research Specialist Kimberly Librero, they examine municipal data from 2000 to 2020.
Firms and consumers shift toward areas with direct transport access, reshaping where economic activity takes place.
At the same time, municipalities hosting RoRo ports benefit from stronger commercial activity.
Business tax revenues in these areas increase by about 17% on average following integration into the network, reflecting higher levels of enterprise activity and investment.
The authors note that improved connectivity creates favorable conditions for business development in port areas. “In the case of RoRo ports, improved connectivity appears to create favorable conditions for business development and commercial activity.”
However, these gains do not translate into broader income growth.
The study finds no statistically significant increase in total income in port municipalities, indicating that the RoRo network may be redistributing economic activity rather than expanding it overall.
“Our findings reveal that maritime infrastructure creates clear spatial winners and losers at scale, generating concentrated economic benefits for a minority of municipalities while imposing welfare costs on the majority,” the authors noted.
How connectivity reshapes local economies
Introduced in 2003, the RoRo Terminal System was designed to improve inter-island connectivity by integrating road and maritime transport.
Vehicles can board ferries and continue travel across islands without unloading cargo, reducing transport costs and travel time.
These efficiency gains make port locations more attractive for businesses.
Firms may relocate closer to ports to minimize logistics costs, while consumers may prefer to shop and trade in areas that are easier to access.
But this concentration effect can come at a cost to surrounding areas. As activity shifts toward ports, nearby municipalities may experience reduced business activity and declining local revenues.
Both tables above compare income trends in municipalities that host RoRo ports and those located nearby. The pre-treatment results show that the municipalities had similar income patterns before the ports joined the RoRo network. After integration, host municipalities show no significant change in income, while neighboring municipalities experience an average decline of about 6.5%, suggesting that economic activity may shift toward port areas.
Infrastructure and economic growth
Infrastructure investments are widely seen as a key tool for promoting economic development.
In countries with challenging geography, like the Philippines, transport infrastructure can help connect markets and improve mobility.
“A frequently proposed strategy for stimulating inclusive growth is strategic investment in infrastructure, particularly in lagging regions,” the authors explained.
This is especially relevant in the Philippines, where the country’s geography creates barriers to economic integration.
“The fragmentation of the Philippines into more than 7,000 islands creates natural barriers to economic integration,” the study noted.
By improving inter-island connectivity, the RoRo network aims to speed up and improve the efficiency of the movement of goods and people.
Implications for infrastructure planning
The findings highlight the importance of considering how infrastructure investments affect different communities.
While transport projects improve connectivity and economic integration, their benefits may not automatically spill over into surrounding areas.
Instead, improved transport access can create strong local growth centers that attract businesses and investment.
“Infrastructure remains essential for economic integration in archipelagic economies,” the authors said.
They added that complementary policies may help ensure that more communities benefit from improved connectivity.
These may include support for local businesses, regional development programs, and investments that help nearby municipalities take advantage of new transport links.
