Abstract

High-growth firms appear to be key drivers of new industries and technologies. Here we investigate the contribution of these and other types of firm to a technology cluster, in the context of ‘creative destruction’ shaping the evolution of the cluster. Evidence on the reallocation of scarce resources through processes of creative destruction is scarce. But in a cluster the effects of creative destruction can be traced through such developments as firm exits and entries change in firm size distribution and acquisition of firms. We apply churn analysis, firm size transition analysis and analysis of acquisition to the technology cluster in Cambridge UK over twenty years. Firm growth contributed two-thirds of all new job creation, while entry-exit turbulence accounted for one third of job creation. High-growth firms accounted for a quarter of jobs created in the Cambridge cluster during this period, without ever making up more than 3% of all tech firms. There has been an increase in average firm size and profitability. A fall in entry rates and fewer firms moving up into larger size categories in recent years point to adverse conditions for innovative new firms even before the financial crash.
探索技术集群增长的要素:来自英国剑桥的证据
高增长企业似乎是新产业和新技术的关键驱动力。在“创造性破坏”形成集群演变的背景下,我们研究了这些和其他类型的企业对技术集群的贡献。通过创造性破坏过程重新分配稀缺资源的证据很少。但在集群中,创造性破坏的影响可以通过企业退出和进入、企业规模变化、企业分布和企业收购等发展来追踪。我们运用流失率分析、企业规模转变分析和收购分析对英国剑桥大学的技术集群进行了20多年的研究。企业增长贡献了新增就业的三分之二,而进出动荡占新增就业的三分之一。在此期间,高增长公司创造的就业机会占剑桥集群的四分之一,但在所有科技公司中所占的比例从未超过3%。企业的平均规模和盈利能力都有所增加。近年来,进入率的下降和越来越少的公司进入规模更大的类别,表明即使在金融危机之前,创新的新公司也面临不利的条件。
