摘　　要：2019年5G建网的进展迅速,2020年是5G商用加速起飞的关键一年,由于5G所分配的频谱远高于3G/4G,这导致了5G高昂的建网成本,通信运营商将面临建网资金紧张,运营可能亏损的困境。对2020年5G的投入与收入、建网成本与运营成本做了分析,由于5G是全球高度统一的先进技术标准,按信息经济定律即麦特卡尔夫定律和摩尔定律来分析,5G的长期社会经济效益将非常可观。针对如何降低高昂的建网成本与运营成本,提出了深化共建共享5G网络与高度共享电视黄金频谱二条关键举措,最后对主管部门提出了具体建议,期望5G能早日建成。The progress of 5 G network construction is rapid in 2019,and 2020 is the key year for 5 G commercial acceleration.Since the allocated spectrum of 5 G is far richer than 3 G/4 G,it leads to high cost of 5 G network construction and communication operators face the dilemma of network construction funding shortage and possible loss of operation.This paper analyzes the investment and income,network construction and operation costs of 5 G in 2020.Since 5 G is a globally highly unified advanced technology standard,the long-term social and economic benefits of 5 G will be considerable according to the law of information economy,namely Metcalfe’s law and Moore’s law.In view of how to reduce the high costs of network construction and operation,this paper proposes two key measures to deepen the joint construction and sharing of 5 G network and highly shared TV golden spectrum.Finally specific suggestions are provided to the competent departments,and 5 G is expected to be completed as soon as possible.
