| Since the existence and development of regional economy is based on the geographic space in which they are located. From this view, there provides a new thought for the study of the layout of regional economic space, that the research on regional economic space can refer some methods in geographic space and physical space. The most important theory which combine regional economy, physical space and geographic space is economic space field theory. The paper, based on the economic space field theory, is going to explore the spatial characteristics of potential for regional economic development and do simulation analysis for the formed field effect.Because the evolution of spatial structure of regional economy has a significant spatial characteristics, geography technology can be used for the research of regional economy. Using ArcGIS tools to analyze the regional economy, on the one hand you can store and manage spatial economic data better; on the other hand, you can analyze and simulate the evolution for spatial structure of regional economy through the graphical thinking. In particular, based on the development platform of ArcGIS, using a general programming language can comply more advanced simulation of time and space for regional economy. The paper choose VBA developing environment ebedded in ArcGIS desktop edition to simulate the spatial field effect formed by the potential for regional economic development.Field theory of economic space consider point elements as the field source has concentration and radiation characteristic on the surrounding media and economic space field has salient continuity. The paper customed toolbar of regional development potential model by using a large number of programmable ArcObjects components. It realize the function as following:firstly, the economic property data of the space unit is given to the corresponding region on the map of administration center; secondly, select appropriate spatial interpolation method to study the evolution of the spatial structure for the regional economic properties;third, as a number of economic factors field can exist in the same space, and different way to superposition produce different result, so according to the economic factors model between regional development potential and economic factors, which is the result of multiple linear regression analysis, superposing economic factor fields will get field-effect diagram of regional development potential and realize the spatial visualization of the potential for regional economic development.AnRen county is chosen as the empirical subject in order to verify the practicality of the spatial visualization model of potential for regional economic development. By studying the development potential field of AnRen county in 2008 formed by superposition of economic factor field to analyze the spatial structure of regional economy. It helps to grasp the overall space layout of regional development potential in AnRen county and help to introduce economic elements which have positive impact on regional development, promote the reasonable allocation of economic resources, adjust industrial structure and maintain sustainable economic development. |
