摘　　要：采用"成本次可加"方法测度行业的自然垄断属性,已获得国内外经济学界普遍认同和采用。本文采用基础电信固定电话通讯企业数据,选取资本、人力和其他三要素模型,运用双产出分配参数并考虑了所有取值,对固话业务的成本次可加性进行测度。通过该方法定量分析研究表明:随着技术与需求的变化,中国固话业务经历了由超可加向次可加的转变,可以认为从非自然垄断向自然垄断的转变。本文对完善自然垄断定量分析方法进行了探索,并为推动中国电信产业发展提供参考与建议。It has been widely accepted and adopted by domestic and foreign economists to measure the natural monopoly attribute of the industry with the method of "cost subadditivity". This paper uses the data of basic telecom fixed telephone communication enterprises, selects the capital, human and other three factors model, uses the dual output allocation parameters and considers all the values, and measures the subadditivity of fixed telephone business cost. The quantitative analysis shows that: with the change of technology and demand,China’s fixed line business has experienced a change from superadditive to subadditive, which can be considered as a change from non-natural monopoly to natural monopoly. This paper explores how to improve the quantitative analysis method of natural monopoly, and provides reference and suggestions for promoting the development of China’s telecommunications industry.
