The only statistically significant difference between U.S. and Western European firms (5-percent level) is in the importance of locating close to universities. Western European firms rate this as more important than do U.S. firms, though the mean scores are close (2.99 versus 2.65).
Because the importance of these factors does not vary significantly across regions (with the exception noted above), all regions are combined (including those outside the United States and Western Europe) in Figure 4. In tests for significant differences (1-percent level), there are four groupings: (1) Least important are Internet searches and locating close to competitors; these are not significantly different. (2) Research collaborations— whether through sponsored research, collaborations with other firms, or being close to universities—are next in importance. These are not significantly different from one another. (3) Locating close to customers is next in importance and significantly different from all other drivers. (4) Finally, of greatest importance—and significantly different from all other drivers—is being close to highly qualified R&D personnel.
