Industrial Research and Firm Size, Survival, and Growth in American Manufacturing, 1921–1946: An Assessment
利用新数据分析1921-1946年美国制造业中公司规模与研究投入的关系，发现大公司研究强度并不高于小公司，但研究活动显著提升了公司生存概率和增长表现。
The literature on the development of American industrial research suggests that during the twentieth century large firms “dominated” industrial research, and reaped the majority of the benefits from such activity. This paper utilizes new data to analyze both the relationship between firm size and research employment and the impact of research activity on firm growth and survival during 1921–1946. The results suggest that large firms were no more research-intensive than were small firms during the 1921–1946 period. Research activity significantly enhanced the probability of firms' survival among the ranks of the 200 largest manufacturing firms during 1921–1946. Research employment also improved the growth performance of both large and small firms during 1933–1946.
