【摘要】 随着市场经济和知识经济的迅速发展，作为经济活动主体的饲料企业，在区域内面临的竞争越来越激烈，饲料企业为了增强自身的市场竞争能力，提高市场占有份额，必须清楚的了解区域内所有竞争者的实力和自身的竞争优势，及时掌握自身企业和区域内其他饲料企业的市场销售范围、市场占有量和市场分割等情况，为饲料企业制定发展规划和产品销售策略提供参考和依据。当今时代又是信息技术高速发展的时代，尤其是数据库和GIS等技术的迅速发展，如何为企业提供快速、科学、合理的决策依据，已成为区域经济发展管理和决策信息化的迫切需求。本论文的研究课题正是基于这样的背景而提出来的，重点研究在GIS和数据库技术支持下构建区域内饲料企业市场域的关键技术与方法。论文以饲料企业市场域为核心，从企业市场域的理论研究、基于GIS和数据库的企业市场域的构建，以及基于饲料企业市场域的饲料产业链平衡度分析等关键技术进行了讨论，并提出了基本的分析思路和实现方法。 本文首先介绍了工业区位理论、中心地理论和空间竞争理论等经典的经济地理学理论，阐述了这些理论在区域经济主体的空间竞争和市场域形成过程等课题进行的理论研究成果，以此为基础，分析了饲料企业市场域形成和构建的理论研究基础，为进一步分析企业市场域的构建提供了理论依据和方法支持。 为了实现饲料企业市场域的构建，基于voronoi多边形的基本思想，本文进一步提出了基于栅格数据格式的一种weighted-voronoi多边形的方法。通过深入分析的weighted-voronoi多边形的特性，阐述了基于栅格数据格式的weighted-voronoi多边形的实现方法，本文最终建立了基于GIS的饲料企业市场域的构建模型和方法。 基于饲料企业市场域理论，本文提出了饲料企业市场域产业链平衡度模型，并对饲料企业市场域内的饲料产业链平衡度进行了理论分析和探讨，为饲料企业分析研究区域内饲料企业的生产、销售情况和制定企业发展规模提供科学、合理的理论参考。 在本文的最后，介绍了基于饲料企业市场域和饲料产业链平衡度模型的安徽省饲料企业市场域的分析实例。更多还原

【Abstract】 Along with the development of market economy and knowledge-based economy, the animal feed business enterprises, as the participators of the economic activities, face more and more furious competition. In order to build up themselves competition abilities, increase market occupied quota, the animal feed business enterprises must know well their all competitors’ strength and the competitive advantages of itself, knows the competitors’ and itself market area, market occupation in the region, offer basic consults to establishing the development programming of the animal feed business enterprises with products sale strategies. Now it’s the times of the fast development of information technology, especially GIS and database technology. It becomes an urgent task that how to provide scientific, reasonable consults for the decision-making and management of regional economy development. This paper discusses the key technologies to build the market-area of the feed business enterprises, based on the GIS and database technologies. Around of the topic of market-area of the feed business enterprises, academic disquisition of market-area, building of market-area based on GIS and Database technologies, the Equilibrium Index Model of Feed Industry Chain based on market-area are discussed in the paper.Firstly, this paper introduced the industrial location theory, central place theory and spatial competition theory, expatiating the application of these theories in regional economic competition, and analyzed the advantages and disadvantages of these theories in the business enterprise market area building.In order to realize the feed business enterprises market-area building, according to the basic theory of voronoi polygon, this paper put forward a method of weighted-voronoi based on the raster format data analyzing the characteristics of weighted-voronoi polygon, expatiate the technique of weighted-voronoi polygon realization based on the raster data.Based on the feed business enterprises market-area theories and methods, this paper put forward the Equilibrium Index Model of Feed Industry Chain, and proceeded the academic analysis to the Equilibrium Index of Feed Industry Chain based on the market-area of feed business enterprises.At the end of the paper, Anhui feed businesses enterprises’ Equilibrium index of Feed Industry Chain, based on the feed business enterprise market-area and the Equilibrium Index Model of Feed Industry Chain, has been analyzed as an instance.更多还原
