 note = {A business strategy research has tried to find ways for minimizing competition between firms. But, the notion of network externalities gives us a new point of view. In the particular situation, we can get the effect of network externalities if we encourage rivals to utilize the technology innovated. There are some conditions to get the benefit. The most important condition is that first movers (innovator) can get much profit if it maintains more superior quality than the one of followers (imitators).
　A lot of followers compete each other, decreasing their products' prices. Lower prices of followers' products bring a larger user base that becomes the source of network externalities. First movers should maintain better quality than followers in order to make use of the effect of network externalities.},
