A Study On The System Of Agriculture Information Service Of China Under Internet Circumstances

Agricultural information service system is the main part of agriculture informationization. Since "Jin Nong project" was put forward in China to construct the system of agricultural synthetic management and information service, several billion yuan were invested to construct agricultural information network at county-and-above levels throughout the country, but network information coming into the rural areas that is the extension of the agricultural production field was blocked, which severely effects economic benefit. On the background of the finite government investment and the low farmers' income, the construction agricultural information service system must pursue the path which gets along with China conditions in virtue of science management and system innovation. Therefore, combining theories with practices, it is necessary to research how to construct an agricultural information service system with complete structure, abundance drive and output high efficiency.In the paper, the basic principles of economics are groundwork, the scientific methods of system engineering are analysis tools, and the methods integrating quantitative analysis and qualitative analysis are used. First of all, production subsystem, prepagation subsystem and apply-effect subsystem are designed according to information system operating principle of "source"-"current"-"use" as start point, profoundly analyze and demonstrate internal structures, element states and mechanisms of action about the three one. In the second, we discuss drive mechanism and operation model of agricultural information service system operation, and conclude that "the government-dominated, combine-promoted model" is suitable for the current situation in China. Thirdly, we work out an index system, construct a system integration evaluation model by applying the analytic hierarchy process method and multi-level fuzzy evaluation method, test practically the agricultural information service system of Hebei province, and prove that both index system and evaluation model are valid. The last section is the conclusion, we summarize some important research viewpoints and give some operable suggests. The study is of theoretical value and practical significance to fill up deficiency of the research area in China.The first part is analysis of background, containing those first three chapters, which discuss the development of theory and application. The first chapter is "introduction". It briefly summarize the topic selection foundation, study meaning, object, purpose, content, method, and potential flare points. Chapter 2 is "several concept and theory foundation of agricultural information service system management". It differentiates and analyzes some interrelated basic conceptions, and then introduces the new economical rising theory, information economics theory and information management theory mainly, which are the theory foundation of this study and offer those important ideas and methods. Chapter 3 is "management actuality and problem analysis of agricultural information service system". Firstly, it states the theoritical contribution by national academia of agriculture informationization and agricultural information service study. Secondly, it briefly state development current situations and experiences of agricultural information service system in other countries. Lastly, national management current situations and questions of agricultural information service system are analyzed, which offered practical basis for the study key points.The second part contains three chapters, from the forth chapter to the six one, which are the core of agricultural information service system study. Chapter 4 is "study of agricultural information production subsystem". In this chapter, we state meaning differences of agriculture information resource and information products, design producing process model of agriculture information production. Combining with actual data of Hebei province agriculture information resource program, we definitely investigate agriculture information resource program, information source, gather and processing, data standardizing and sharing of database, and put forward sharp management measure as well. Chapter 5 is "study of agriculture information propagation subsystem". Considering trait of national agriculture information propagation, we comparatively evaluate different forms of information propagation, construct the basic structure of agriculture information propagation subsystem by "five W model" of applied propagation theory. We analyze those factor existing states and propagation mechanism in the propagation subsystem, sum up some experience models of breaking through the"one km in the end", and compare and sum up the profit mechanism and calculated circumstance containing in those models. Chapter 6 is "study of agriculture apply-effect information subsystem". In this chapter, we defined meaning of agriculture information apply-effect, construct the subsystem, and analyze those main effectual elements and function mechanism of information apply-effect. Focusing on "four efficiencies", we put forward five group dominating factors which could promote information apply-effect. In succession, we analyze conditions, factors and function mechanism about "network to door" information apply-effect and put forward some measures to promote network information apply-effect.The third part is system countrl and management, it consists of chapter 7 which is "drive mechanism and operation model of agricultural information service system", the public goods characteristic of agricultural information is the government-dominated theoretical foundation. Integrated multi-agent is likely to shape the joint force of system operation and it is necessary to. It has appeared in the integrated construction successful model of government, enterprises and society.The fourth part consists of chapter 8 which is "the comprehensive evaluation of agricultural information service system". In this chapter, we design an index system of agricultural information service system evaluation. Firstly, we elicit those monolayer taxis weight vector by applying the analytic hierarchy process method and then regard them as index weight in multi-level fuzzy evaluation. Next, we work out combination weights of every layer index to chief object, and then understand importance of different index to chief object in virtue of the combination of weight taxis. Therefore, we can ascertain those objects which are mainly managed and supervised. By applying those outcomes of multi-level fuzzy evaluation, we can mensurate the structure and level of system and then evaluate different areas, which is good to study and boost among districts. We test practically the agricultural information service system of Hebei province by using expert survey data, and prove that both index system and evaluation model are valid.The fifth part consists of chapter 9 which is "research conclusion". According to comprehensive consideration of theoretical analysis and applications, we summarize those main issues of the paper and give some operable suggests about those important fields of strengthening agricultural information service system management.
