论文摘要
通常，机构和文化通常会根据当前的环境激励措施而适应地发展。但是有时制度变化是由于随机驱动器超出当前适应性的原因，包括漂移，路径依赖性，盲目的模仿和互补的合作。从社会系统变化的选择性和随机组成部分中删除，从长远来看，我们能够确定组织发展的关键特征。进化方法提供了组织科学丰富的理论，可以通过跟踪特定的有益或有害特征来展示组织的演变。我们借助两个最应用的进化模型，价格方程式和BET-HEDGING模型，在20,000个Minecraft社区的机构演化中经验衡量这些不同的驱动因素。结果，我们发现了对行政规则和信息规则的强烈选择压力，这表明它们与社区健身的正相关是其频率变化的主要原因。我们还发现随机驱动器降低了管理规则的平均频率。根据进化的围栏进行解释，结果是有道理的。我们通过BET-HEDGIN结果表明，机构多样性有助于与信息，沟通和经济行为相关的规则的增长和稳定。
Institutions and cultures evolve adaptively in response to the current environmental incentives, usually. But sometimes institutional change is due to stochastic drives beyond current fitness, including drift, path dependency, blind imitation, and complementary cooperation in fluctuating environments. Disentangling the selective and stochastic components of social system change enables us to identify the key features to organizational development in the long run. Evolutionary approaches provide organizational science abundant theories to demonstrate organizational evolution by tracking particular beneficial or harmful features. We measure these different drivers empirically in institutional evolution among 20,000 Minecraft communities with the help of two of the most applied evolutionary models, the Price equation and the bet-hedging model. As a result, we find strong selection pressure on administrative rules and information rules, suggesting that their positive correlation with community fitness is the main reason for their frequency change. We also find that stochastic drives decrease the average frequency of administrative rules. The result makes sense when explained in light of evolutionary bet-hedging. We show through the bet-hedging result that institutional diversity contributes to the growth and stability of rules related to information, communication, and economic behaviors.
