Development Evaluation Model And Empirical Study Of Triple Play Based On Entropy-weight Topsis Method

As an important industrial convergence phenomenon,triple play is playing an increasingly important role in promoting scientific and technological progress,stimulating economic growth and improving people’s livelihood.The development of triple play in foreign countries started earlier compared to the domestic,providing a high quality and competitive price of diversified information services for people.Triple play in China has experienced more than ten years of development.Periodical results have been achieved in technology,market and business model.In order to explore the development mode and path in China,the State Council released three batches of pilot areas(cities)in June 2010,December 2011 and March 2012 to speed up the overall advance of the triple play.Development evaluation is an important content of triple play research.China’s triple play has just started and exploring evaluation problems of it have practical significance.In theoretical level,the research can improve the relevant arears of study;and in practical level,it is beneficial to summarize achievements and shortcomings of triple play in China,which helps government,supervision and research institutions measure the development process of triple play objectively,find the breakthrough of it,and guide the popularization practice.The paper first summarized the concept,motivation,details and developing trend of triple play,analyzed the development process and assessment evaluation of it,which preliminary laid the theoretical basis of evaluation study.Secondly,based on the principle and ideas of development evaluation index system construction,combining experts’opinions and suggestion,this paper constructed the development evaluation index system of triple play.Then,because the comprehensive evaluation method overcomes the shortcomings of using a single evaluation method,this paper chose the entropy weight method to determine the weight of the index and carried on the comprehensive evaluation through the TOPSIS according to the objectivity and heterogeneity of the evaluation system.The development evaluation model of triple play based on entropy-weight TOPSIS method is established.Finally,set Bejing,Tianjin and Hebei as an example,this paper applied the model in practice.Feasibility of the evaluation model is proved,and some suggestion on coordinated promotion of triple play in Beijing Tianjin and Hebei is put forward based on the results.The establishment of triple play evaluation system is based on the literature review and practical investigation,which includes 3 first level indicators and 13 second level indicators,including infrastructure indicators,user access indicators and business development indicators.The study proved the entropy-weight TOPSIS method can well applied in practical.The empirical research showed that the basic network readiness is still the key factor in developing triple play in China.There is a gap between Beijing,Tianjin and Hebei in the level of triple play,and the"digital divide" and departmental conflict of interest are the main reasons affecting the coordinated development of the three places.This paper proposed the strategy suggestion from two aspects of infrastructure construction and business development,to provide ideas for the triple play comprehensive advancement.
