Microblog is one of the main applications in web2.0, its openness, interactivity and convenience is favored by many users, and it becomes one of the most potential applications in the mobile internet era. As the rapid development of microblog, it emerges all sorts of chaos phenomenon, and exist serious information quality problems, which hinder its development. There filled with all sorts of chaos phenomenon in microblog because of the missing of Gatekeeper, the characteristics of information fragmentation, and different level of users. Large user group and real-time communication function of microblog caused rumors and the information overload, the convenient information post and forwarding caused a lot of information redundancy, and the missing of Gatekeeper in information post make the distorted information, the trivial information and the vulgar information filled with microblog. At the same time, the rapid development of microblog marketing triggered a series of nonstandard operation, even criminal behavior. According to the survey of problems in the use of microblog by CNNIC, the information content of microblog cannot meet users'quality demand, including the amount of information is too large, the effective value is low and so on. The quality problems of microblog information content have become important problems which affect the development of microblog and effective use of the network information resources, the quality management of microblog information resources is urgent. At present, the researches of microblog information quality at home and abroad mainly focus on information quality evaluation and analysis of information quality problems and solutions. In the research of information quality evaluation, it is focuses on empirical analysis abroad, and on constructing evaluation index system at home. In the research of problems analysis of information quality, it is focuses on how to solve the quality problems by information technology abroad, and on analyzing problems and solutions aimed at the microblog information in a particular field at home. In conclusion, there are fewer researches on the content quality of microblog information and its influence on the users'utilization. The quality evaluation of microblog information content and impact analysis can more accurately get the key factors affecting users'utilization of microblog information, and effectively improve the content quality of microblog information and it utilization. In this paper, the author takes the sina microblog data as samples to do empirical research, evaluates the content quality of microblog information and does contrastive analysis, and then analyzes the influence of microblog information quality on the users'utilization, in order to get the key factors affecting users'utilization of microblog information, and provide strategies and advises on controlling microblog information quality and improving microblog information utilization.The structure of the paper is divided into introduction and seven parts of main body.The first chapter is the introduction. It mainly introduces the research background and significance, research status at home and abroad, the research content, methods and innovation points.The second chapter is the basic concepts and theoretical basis of the study. This chapter expounds the concepts of the information quality, the theory of information evaluation, and the methods of content analysis. Based on the theory of information quality, the author defines the scope of microblog information quality, in order to evaluate the content quality of microblog information. Information evaluation theory provides the research methods and tools for carry out quantitative evaluation on content quality of microblog information. The theory of content analysis is mainly used for microblog information classification and analysis on the type of information content, it provides the theory support and guidance.The third chapter constructs theoretical framework of information content quality evaluation of microblog, and builds theoretical hypothesis on the influence of information content quality to microblog utilization. The paper set up an evaluation index system of microblog information content quality according to the information quality theory and the characteristics of microblog information, does index weight assignment through users'survey, and provides theory basis for quantitative evaluation of information content quality of microblog. The theoretical hypothesis will be tested in the following empirical research.The fourth chapter is the analysis and evaluation on the information content quality of microblog, and summarizes the quality characteristics of microblog information content in different fields. The author does this research by taking sina microblog data for example, selecting some microblog users from four fields of science and technology, public security, real estate and environmental protection, and collecting their information content of microblog as sample data.

The sixth chapter analyzes the influence of information content quality on the microblog forwarding through the empirical study with two variables that one is the description index of microblog information quality as independent variable and the other is microblog forwarding as the dependent variable. This chapter analyzes the influence from the perspective of information quality through the sample data which collect from four microblog user groups of science and technology, public security, real estate and environmental protection, in order to find the key factors in different user groups. The seventh chapter analyzes the influence of information content quality on microblog reviewing in the same way, and summaries the key quality factors that effecting utilization.The eighth chapter is given some suggestions. The main content and conclusion of the dissertation are concluded. The disadvantages are reflected. The future research is prospected.The discussion of the implications for both theory and practice is as follows:Firstly, there are different characteristics of information quality in posting information of microblog in different user groups, which shows that the microblog users'field has a significant influence on its information content quality of microblog.Secondly, among the information quality index, the information type and popularity have the most significant difference among the user groups, and the following is the amount of text words and hyperlinks, the least is the information authenticity and professional editing.
