Commerce and industry in the province is in full swing as manifested by the growing number of business establishments, construction of high rise buildings, and availability of Automated Teller Machines (ATM).

Based on the result of the 1999 Updating of List of Establishments (ULE), the number of establishments in the province has reached 2,890 as against to 1998 with a total of only 2,641, registering a positive growth of 9.4 percent. Large percentage of these businesses belongs to the wholesaling and retailing category and majority of which are single establishments meaning they do not have branches.

To date, Marinduque has no existing shopping malls but there are some commercial buildings. Multinational companies are not present in the province hence the ratio of unemployment here is high since majority of the establishments here have one (1) to four (4) personnel only.
