PORTLAND — A new report says the cruise ship industry contributed $45 million to Maine’s economy last year while generating more than 800 jobs.

An independent study commissioned by the Cruise Lines International Association concludes that cruise line companies and their passengers and crew contributed more $42 billion to the U.S. economy last year, a nearly 5 percent increase from 2011.

The 120-page study says that cruise lines had a $45 million economic impact in Maine, a figure that includes cruise line spending on goods and services, passenger and crew spending, and other expenditures such as air travel, wages to cruise line employees, travel commissions paid by cruise lines and related expenses.
