Dynamics of Organizational Populations

当长时间检查时， 不同人群中的组织最初增长缓慢，然后 短暂快速增长，达到高峰，然后下降并趋于稳定 (and最终往往会下降）。 该项目延续了 试图通过发展来解释这种模式的研究 一套基于社会学理论的数学模型， 密度依赖的进化，也就是说，出生的模式， 组织的增长、衰退和死亡率， 人口中的组织数量。 在新发行的 这个项目所面临的问题是 年龄对组织规模和密度的影响 与人口数量的关系以及密度理论的应用 社区层面以及个体人群。 数据 将收集人口和社区的金融 研究这些问题的机构和报纸出版公司 凭经验 这个项目不仅有助于我们了解 在很长一段时间内塑造组织结构的力量， 也将有助于提供一个理论上的 解释组织变革如何产生变革的结构 在社会上

When examined over long periods of time, counts of the number of organizations in diverse populations initially grow slowly, then grow rapidly for a short time, peak, then decline and stabilize (and often eventually decline). This project continues a line of research that seeks to explain this pattern by means of developing a set of mathematical models based on a sociological theory of density-dependent evolution, that is, the pattern of the birth, growth, decline, and mortality of organizations as a function of the number of organizations in a population. Among the new issues that are being confronted by this project are the disentanglement of the effects of age versus size of organizations and of density versus mass of populations and the application of density theory to the community level as well as to individual populations. Data will be collected on populations and communities of financial institutions and newspaper publishing firms to examine these issues empirically. This project will not only contribute to our understanding of the forces shaping organizational structures over long time spans, but also it will contribute to the provision of a theoretical structure for explaining how organizational change produces changes in society.
