论文摘要
组织与环境和其他组织互动，这些互动构成了学习和进化的重要方法。为了克服他们在生存过程中面临的问题，组织当然必须采用单独和小组中的生存策略。这项研究的目的是评估一组预后因素（组织，规模，协作策略等）在组织网络生存中的影响。使用时间数据的统计方法用于分析数据。我们已经使用Kaplan-Meier产品限制方法来计算和绘制生存的估计，而假设检验被用于比较几组的生存时间。回归模型用于研究连续预测因子的效果以及一次测试多个预测因子。由于发现了几个预测因素的违反比例危害的行为，因此使用加速的故障时间模型来研究解释变量对网络存活的影响。
Organizations interact with the environment and with other organizations, and these interactions constitute an important way of learning and evolution. To overcome the problems that they face during their existence, organizations must certainly adopt survival strategies, both individually and in group. The aim of this study is to evaluate the effect of a set of prognostic factors (organizational, size, collaborate strategies, etc.) in the survival of organizational networks. Statistical methods for time to event data were used to analyze the data. We have used the Kaplan-Meier product-limit method to compute and plot estimates of survival, while hypothesis tests were used to compare survival times across several groups. Regression models were used to study the effect of continuous predictors as well as to test multiple predictors at once. Since violations of the proportional hazards were found for several predictors, accelerated failure time models were used to study the effect of explanatory variables on network survival.
