It's not the same thing, you do not get much benefit from running in place.

It depends on what your goals are.
As "." said, running in place works your muscles differently than running. This applies to ligaments and tendons, too.
If your goal is to be competitive in races, a season of running in place can leave you unprepared for racing.
But, if your goal is cardio/pulmonary/vascular health, running in place is one of several exercises you can do. My guess is one would be as effective as the other if the intensity (effort) and duration are comparable.
If you are a runner, but don't have a treadmill, running in place is a good exercise on days where you can't run outdoors. You might not be able to run outdoors because of icy surfaces or dangerous winds.
When record setting ultramarathon runner Arthur Newton couldn't run outdoors, he ran in place with high knee lifts.
