Research Of Regional Agriculture Industry Advantage Analysis And Structure Optimization Tool Based On AJAX

As a basic industry in national economy, agriculture is always holding an important place in the development of Chinese economy. China has a vast territory, so agriculture shows a great regional difference. We have to take actions that suit region circumstances and arrange agriculture industries according to regional characteristic. China has a huge population, and has relatively limited resources. In order to make sound use of limited resources and improve the productivity and competitive strength and increase income of farmers, we have to analyze the comparative advantage of each industry in agriculture, revise and optimize the industry structure of agriculture based on the analysis result. Take modern information technology keeps penetrating to agriculture domain as a background.This research is trying making use of advanced information technology to improve the ability of regional agriculture industry structure adjustment and optimization and promote the level of agriculture information-oriented development. This is a research of both theoretical and practical significance.According to the research status of regional agriculture comparative advantage analysis and industry structure adjustment and the current development of information technology, this paper take regional agriculture industry advantage and structure optimization system (RACAPS) as research target. This paper introduces Ajax technology and related application frameworks to build an auxiliary toolkit of decision support system for agricultural policy maker and economy researcher.This research studies the comparative advantage theory and regional agriculture industry structure adjustment and optimization theory, and references a large number of documentaries of empirical research. This paper design the RACAPS based on the research of related theories. RACAPS implements a N-tier architecture, and is developed by ASP.NET 2.0 and C# language, based on .NET 2.0 framework. RACAPS use Microsoft SQL Server 2005 as database management system, and use open source control ZedGraph to generate charts. RACAPS use ASP.NET AJAX framework to implement Ajax functions, and has improved the user experience and efficiency greatly.This research involves subjects including operation research, agriculture economics, and information technology. The main achievement of this research is making theoretically summary of common ways of regional agriculture industry advantage analysis and structure optimization, and implementation of decision support toolkit. The toolkit includes an flexible tool for agricultural data integration and advance query, a"one page style"component of regional agriculture industry structure optimization which provides an agile arguments setting method that enables applying sensitivity analysis and usage of data and comparative advantage analysis result, and a component that can solve the linear programming model and its dual problem by simplex method. RACAPS, as an auxiliary toolkit, has made a solid foundation of building regional agriculture decision support system.
