基于网络融合的网络型产业效率评估
首发时间:2009-08-28
摘要:本文在我国三网融合背景下,运用DEA-AP模型和DEA-Windows方法对网络型产业(本文特指电信和广电产业)的效率进行测度,并对结果进行了分析。研究表明三网融合可以实现网络资源的高度共享,应该是电信运营商和广电运营商共同努力的方向:(1)电信产业的整体技术效率除2002的0.99外(接近有效值1),都表现为整体有效;(2)电信运营商中除了中国电信的效率从2004年到2006年是不断下降的,其他运营商的效率都稳步提升;(3)从2004年到2006年,三个广电运营商的技术效率也表现为稳步上升。

Efficiency Evaluation of Network Industry: Based on Network Integration
Abstract:Based on network convergence of our country, this paper used the methods of DEA-AP and DEA-Windows to evaluate the efficiency of the network industry (especially telecom industry and Radio and TV industry), and analyzed the results of measurement. Results show that three nets fusion can realize network resources sharing, which should be the common direction of telecom operators and radio and television operators: (1) the overall technical efficiency of telecommunication industry except in 2002 is 0.99 (near to 1) are efficient; (2) from 2004 to 2006, except the efficiency of CHINA TELECOM is declining, other telecom operators efficiency are steadily rising, (3) from 2004 to 2006, the technology efficiency of three Radio and TV operators are steadily rising too.
