The regional and temporal nature of hypercompetition
研究检验全球技术密集型行业是否普遍存在超级竞争，基于美欧日中1980-2018年数据，发现超级竞争并非普遍现象，而是局限于特定区域、时间和行业生命周期阶段。
Numerous scholars have suggested that the global technology-intensive sector has become hypercompetitive, yet few have tested this empirically. Those that have find seemingly conflicting evidence. Applying commonly used measures, we explore whether this could be due to hypercompetition being more time and context specific than previously thought. Based on data from the United States, Europe, Japan, and China covering 1980–2018, we find no indication of a generalized increase in business performance volatility in this sector across regions. We do find a declining stability in the performance of Japanese firms over the study period, but in US firms only leading up to the burst of the dotcom bubble. A structural break analysis helps us conclude that hypercompetition is a phenomenon limited in both location, time, and industry, linked to industry breakpoints across its life cycle.
