Assessing Forest Service Recreation Trends with Shift-Share Analysis.

摘要

Shift-share analysis is used to describe recreation growth in the Regions of the Forest Service, U.S. Department of Agriculture, between 1970 and 1988. Growth is partitioned into three components: national trend, recreation mix, and regional competition. National trend accounted for nearly all recreation growth in slow-growing regions. Shifts in regional competitive position accounted for much more recreation growth than did recreation mix. Substantial recreation use shifted from the Northern States to the Sunbelt States.
