MILWAUKEE (AP) -

A new study raises concerns about Wisconsin's long-term economy, in part because it relies too heavily on industries that are now facing a decline.

A Milwaukee Journal Sentinel report says three of the state's five largest sectors have to do with paper and printing. That could be a concern as the nation shifts its demand toward digital media.

The study also says Wisconsin's main industries aren't as globally minded as are manufacturers elsewhere. That could be another competitive disadvantage.

The study was commissioned by the Wisconsin Economic Development Corp., the state's main job-creation agency. It was released Tuesday.

WEDC vice president Lee Swindall compares Wisconsin's paper-based economy to Michigan's auto sector. He says paper companies are adapting but they're still vulnerable.
