经济资源配置高效率,它不仅要求具备帕累托最优的三个边际条件,而且必须将外差因素计入。因此,分析外差因素的类别、成因和内在化,具有重要的现实和理论意义。一、外差因素类别经济外差因素是指经济行为人相互作用引致的受益和受损效应。或由一行为主体活动所产生,但其成本、收益或风险可转嫁为其它行为主体的行为效应。外差因素按其效应、来源和行为特性可大致分为如下几种:
The efficient allocation of economic resources requires not only having the Pareto optimum three marginal conditions, but also factoring in externalities. Therefore, it is of great realistic and theoretical significance to analyze the categories, causes and internalization of the factors of external disparity. First, the types of external factors Economic differences in economic externalities refers to the interaction of economic agents caused by the benefit and damage effects. Or by one line as the main activity, but the cost, return or risk can be passed on to the behavior of other actors. External factors according to their effects, sources and behavior can be broadly divided into the following categories:
