| On January 7th 2009, the Ministry of Industry and Information Technology of the People's Republic of China provided 3 the third generation mobile communications (3G) licenses for China Mobile, China telecom and China Unicom. This act symbolizes that our country entry into the 3G era formally. The mobile communications industry has already became one of the industries with the fastest developing speed in our country. With the era of data services and mobile multimedia arrivals, mobile communications market will be leaded to profound changes in competition, competition is no longer between individual enterprises on products and services,but among mobile communications industry chains which depend on industry collaboration. The innovation capability of the mobile communications industry chain will be the key to enhance the competitiveness of our mobile communications industry and maintain sustainable development. How to achieve stability market position, form a good competitive situation, improve innovation capability of the mobile communications industry chain will be the problems to be solve urgently in the 3G era.Most of the researches on the mobile communications industry chain at home and abroad are still qualitative analysis, foreign researches are about structural characteristics, evolution rule, environment of the industry chain, development trend of various entities on the mobile communications industry chain and so on. In our country, the researches are about division level and structure of the mobile communications industry chain, its developing problems, driving and control force, coordinated development of its nodes and so on, these researches on mobile communications industry chain are gradually enriched and improved. The study on the innovation of the mobile communications industry chain is also mainly about the qualitative researches, such as innovative strategies, innovative models and so on. Only a few quantitative researches are mainly about the market analysis or the research on the members of the mobile communications industry chain,such as the mobile communication facility industry, operators and so on. There is no systematic study on innovation system of the mobile communications industry chain, and there is no specific research about the overall evaluation index system and model of them.In this paper, my object is the innovation system of the mobile communications industry chain. According to status of the mobile communications industry chain, I put forward the concept of the innovation system of the mobile communications industry chain, and based on the analysis of its structure and evolution path, I summed up the innovation system model of the mobile communications industry chain, discussed its innovation pattern, constructed the evaluating index and the evaluation model, at last I analyzed and evaluated the innovation system of the mobile communications industry chain from the knowledge innovation, the process innovation, the product innovation, the marketing innovation, the institutional innovation, the management innovation and the organization innovation.First of all, I analyzed and summarized the relevant theories of the mobile communications industry chain. Based on research about the theories of supply chain,value chain, industry chain and industrial clusters, I studyed the differences and the links of them. Then I summarized the concept of the mobile communications industry chain is a link which composed of node enterprises from different industry with different responsibilities and different division of labor who aim at the end-user market. They all take the information commodity as the object. The node enterprises on this chain relate closely, they continually process the information, such as collection, reorganization, classification, storage, transmission, exchange etc, to provide the information product for users in order to achieve the value increment of information. At the same time, I carried on the analysis to the mobile communications industry chain's member, introduced the type of its terminal product, discussed the structure of the mobile communications industry chain and its sub-industry chain's constitution, summarized the technical and the structural evolution path of the mobile communications industry chain. Based on this, I analyzed the present situation and the development trend of the mobile communications industry chain, summarized. the influencing factors to the competitiveness of it.from the industry chain collaboration capabilities, the industry chain operating efficiency, the market expansion capabilities, the industrial chain business model, the innovation capabilities and the government regulation capabilities.Second I discussed and analyzed the related theories of the innovation system of the mobile communications industry chain, summarized the difference and connection of the national innovation system, the regional innovation system, the industry chain innovation system, the industrial cluster innovation system, the industry innovation system and the enterprise innovation system through the analysis of their theories. Then I analyzed the innovation activities of the mobile communications industry chain, proved the necessity to establish the innovation system of it, summarized the concept of the innovation system of the mobile communications industry chain. It considers each nod member as a carrier, it is a aggregate of the innovation subject, the innovation support system, the innovation environment, including all the innovation activities and the entire process of the innovation achievements commercialization, the purpose of the innovation system is to enhance the innovation capability and the innovation performance. Based on this, I analyzed the innovation system characteristics of the mobile communication industry chain, and studied the structure of it from knowledge innovation system, process innovation system, product innovation system, marketing innovation system, institutional innovation system, organizational innovation system, and management innovation system. Discussed the innovation activities evolution path about the innovation system of the mobile communications industry chain along the evolution path of it, and constructed the structure diagram about the innovation system of the mobile communications industry chain, based on this I summarized the constituent elements of the innovation system, and then analyzed the functions and operation mechanism of it.Third, I defined the innovation mode about the innovation system of the mobile communications industry chain. Then I analyzed and summarized the innovation mode according to the correlation theories of the innovation mode and the characteristics of the industry chain, studied the type of the innovation mode, discussed the status and the function of each mode, summarized the present situation and evolution path, based on this, carried on the contrastive analysis our country mobile communications industry chain's innovation mode with foreign's, finded the deficiencies in our country and gave the corresponding countermeasures and suggestions based on the actual situation.Finally, I evaluated the innovation system of the mobile communications industry chain, put forward the concept about the innovation ability of the mobile communications industry chain on the research of the correlatied theories. And then studied the subsystem's features, innovation subject, the status and the function of the innovation subject. Constructed the evaluation indicator system according to the appraisal principle, then I gave a comprehensive evaluation to the integral innovation system of the mobile communications industry chain.Then I summarized the synthetic evaluation indicators from the innovation investment, the industrial chain's operation situation, the industrial chain's innovation output according to the actual situation, and selected the innovation mode according to the characteristics of the various indicators, introduced the computation principle and the method of each evaluation mode. Through the evaluation indicators and the evaluation mode, I carried on the empirical research on the innovation system of the mobile communications industry chain. Through the establishment evaluating indicator and the selection evaluation model, this article has conducted the empirical study to our country present stage mobile communication industry chain innovation system, Through the information and the data from "the annual report of China's telecommunications and Statistics", "China's IT industry map", the Ministry of Industry and Information Technology of the People's Republic of China, I carry out the comparative analysis about the innovation ability of some provinces in our country, and gave the corresponding countermeasures suggestions.
