首先结合移动网络的多层结构特征,利用基于松弛因子测度（SBM）的数据包络分析（DEA）模型构建反映移动网络整体利用率水平的效率测度,并基于2003—2010年国内31省行业数据对移动网络效率、各网络能力利用率进行评价,利用Malmquist指数对效率增长进行分析。其次考察了前述指标在东中西经济区域和南北运营区域之间的差异性。结果显示,移动网络效率损失主要源于基站和短信交换机利用率偏低,而3G启用后大规模网络投资向东部省份和北方10省集中,也是造成相关区域效率损失的重要原因。最后提出政府部门应在3G大规模建设时期加强区域差异化共建共享管制政策的推进。

According to the multi-layer structural feature of mobile network,Slacks-based Measure（SBM） Model of Data Envelopment Analysis（DEA） technique is applied to build the efficiency measurement to evaluate the integrated utilization of mobile network,and then,based on the industrial dataset of 31 provinces in China during 2003-2010,mobile network efficiency and utilization of each network capacity are evaluated,and efficiency growth is also evaluated by using the Malmquist index;next,all these indexes＇ differences among the eastern,western and central regions in economic view and the northern and southern regions in operational view are investigated;the results reveal that,the loss of efficiency is mainly caused by the low utilization of the base station and SMS switch,and the huge network investment distributed to eastern provinces and 10 northern provinces after the launch of 3G is another significant cause for the loss of efficiency in relevant regions;hence,the government is required to intensively carry out the different regional co-construction and sharing policy in the era of large-scale construction of 3G network.
