Usually industry and market positions will be of more value if there are high mobility barriers within the environment.
Some of these mobility can be national in origin like various government regulations. This intervention enhances the importance of obtained positions. In such economies, which are more rigid, strategists have a strong preference to think in terms of market positions first, because they are more difficult to obtain then the necessary resources. In more dynamic economies, where market positions are easily challenged by competitors, the opposite would be true.
In nations where the dominant industries are populated by firms using relatively simple and abundant resources, market positions are far more important, since acquisition of the necessary resources is hardly a worry. If a national economy is composed of industries using complex bundles orc resources, which require many years of painstaking development, there might be a tendency to emphasize the importance of resources over market positions.
