The economy of Villianur is transitioning from a traditionally agrarian base to a more diversified suburban economy. Agriculture remains a foundational element, but it is increasingly supplemented by retail, small-scale industries, and services.
Proximity to Puducherry city has spurred economic development, making Villianur an attractive location for warehousing, small manufacturing units, and residential real estate. Tourism also plays a notable role in the local economy; the constant influx of pilgrims to the Sri Gokilambal Thirukameshwara Temple and the Shrine of Our Lady of Lourdes supports a thriving micro-economy of vendors, transport operators, and eateries.
