THE PERFORMANCE CONSEQUENCES OF SUBFIELD ENTRY
研究了企业进入新兴技术子领域对绩效的影响，发现早期进入能带来正面绩效，基于对3500多家银行在自动柜员机子领域前9年演化的数据分析。
The emergence of technical subfields is a common phenomenon in dynamic as well as relatively stable industries. The proper strategic response to the emergence of a subfield, that is, the decision on whether to enter or not to enter, is a key determinant of future firm performance. We propose that this entry decision is not a simple one. The effects of subfield entry may be influenced by strategic factors related to the subfield as well as to the greater industry environment. In this study, we apply a population ecology framework to the study of subfield birth and evolution and use this perspective to develop and test several propositions related to the effects of subfield entry on performance. The data pertain to the evolution of the automatic teller machine subfield over the first 9 years of its existence for a population of over 3500 banks. Our results support the population ecology framework, generally emphasizing the positive performance consequences of early subfield entry. © 1997 by John Wiley & Sons, Ltd.
