摘要
应用选择理论可以解释人类行为导致的幂律分布现象.通过对选择理论合理而简单的扩展,发现了更多幂律生成机制.研究表明选择理论对于单调的门限分布规律体现出生成机制的一般性;此类机制的扩展对幂律成因的深入研究具有较强的理论意义.
Power law phenomena generated by human activity can be explained by selective theory.More mechanisms are brought forward to generate power law phenomena through the extension of threshold probability.It was demonstrated that selective theory is universal in deducing the power law mechanisms.Therefore,it is significant to extend the theory for further research on the power law phenomena.
