Gis-based Regional Economic Analysis Of System Design And Realization

With the further depth of the country's reform and opening up policy, the national economy have got unprecedented development, at the same time of the rapid development of Regional economy, there is an obvious economic differences within the region, and that has aroused great concern from all walks of life. The traditional research methods of Regional economy is to study the basic elements of time in the time, ignoring the spatial factors, the functionality of the traditional research methods used in the analysis tools is limited, and the research results are relatively single .Because GIS has strong spatial analysis capabilities, and have a more visual image of the visualization capabilities, so people get into the GIS to make up for a lack of traditional research methods, but there are still many obstacles to integrate various economic activities with GIS spatial analysis, the process of spatial analysis and GIS is difficult to achieve a full integration, that limited the application of GIS in the region economic problems to some extent, the spatial statistics analysis of regional economic activity is still at a relatively low level.In view of the above question, this article first discussed the research situation of Regional economic field and its related theory, reviewed the traditional Regional economic analysis method and the related technologies, using the combination of theory and empirical, qualitative and quantitative analysis, the traditional Regional economic analysis method and the GIS spatial analysis combining with GIS as the core technology, electronic map as the information carrier, File Geodatabase format used for storage and management unified geographical spatial data, economic data, the whole system is based on ArcGIS started using the AO modular technology, by calling the ArcGIS started to provide control for the environment 2008 Microsoft Visual Studio, using C# language development platform for the design and development, designed and realized based on GIS Regional economic analysis system. This system not only has the traditional regional economic analysis modules, for instance: regression analysis, principal component analysis, autocorrelation analysis, forecast analysis and so on, and with space analysis function, using this function module we can undertake the layout analysis, buffer analysis and overlay analysis, make the system perfectly with the ability of analysis for Regional economic. Finally, we take Jiangxi province as an example, adopt the regression analysis, principal component analysis, spatial autocorrelation analysis, analysis of regional economic differences characteristics through the Regional economy analysis system, and will display the analyze results with graphics ,tables and special charts forms in detail.Through the above research, we can get the following main research conclusion:The regional economic analysis system designed and developed based on GIS by using the ArcGIS Engine setups has a great improvement than traditional Regional economic analysis tools on the function, the results are more direct-viewing, can better reflect the Regional economic space features, better implementation of Regional economic analysis, and the analytical results obtained diversification for Regional economic analysis provides a better research methods. Therefore, this paper has a certain academic and practical value on the Regional economic analysis and the application of GIS study.
