Research On Evaluation And Optimization Of Business Model Of Internet Of Things Driven By NB-IoT In The L Branch Of China Telecom Co.,LTD

With the continued advance of IoT technology and intensive release of government policies about IoT industry,the layout of IoT industrial ecology has ushered in a critical period.According to the prediction of authoritative institutions,the Intenet of Things will reach tens of billions of connections(about 25% for cellular connections)and a trillion-dollar industry by 2020.The continuous expansion of the Internet of Things application field and the deepening of the application dimension also bring new opportunities for the development of operators.Due to the complex industrial chain of IoT,the current business model of telecom operators is still confined to data transmission channel.The telecom operators have not occupied the dominant presence in IoT market,and the earning generated by data transmission is quite low.Based on the above situation,this paper first elaborated the Internet of Things theory,NB-IoT technology and business model theory,laying a theoretical foundation for the comprehensive analysis of the Internet of things business model.Secondly,this paper uses SWOT analysis method to analyze the characteristics and existing problems of the current Internet of Things business model of L City Telecom Branch from the perspective of external and internal factors.Thirdly,based on the analysis of the impact of NB-IoT on the business model of the Internet of Things,this paper uses the Osterwald business model canvas model to construct the evaluation framework of the operator's IoT business model,and proposes the operator's IoT business model evaluation index.Again,this paper establishes the evaluation system of operators' IoT business model by using Analytic Hierarchy Process and Fuzzy Comprehensive Evaluation Method.Finally,aiming at the telecom branch of L city,this paper obtains scores of various evaluation indexes through questionnaire survey,and comprehensively evaluates the Internet of things business model of the telecom branch of L city.Based on the analysis of the total score of the comprehensive evaluation and the scores of each sub-item,this paper summarizes the problems existing in the IoT business model of L city telecom operators,mainly including low degree of industrial chain convergence and high proportion of channel business.On this basis,this paper proposes corresponding improvement strategies to better adapt to NB-IoT market.
