Spatial Search and Spatial Competition

小米勒9320126 本研究主要探讨两个问题：（1）空间搜寻与区位因素（如可达性）之间的关系;（2）这些关系对市场区域结构的影响。这两个问题都是区位理论的基础。该项目将开发在超级计算机上运行的概率模拟模型。使用仿真模型进行这项研究提供了可能性，包括更现实的假设到定位理论。在研究的第一阶段，分析将集中在空间搜索和空间竞争的控制情况下，面临竞争的零售设施的单一零售商之间的相互作用。在第二阶段，零售商店将争夺空间分散的多个客户群。特别令人感兴趣的是空间搜索对市场区域结构的影响。现有的研究结果表明，搜索行为可以有复杂的，意想不到的，影响设施的光顾模式。 这项研究将有一个显着的影响，通过其新颖的方法，整合模型的搜索和竞争的位置理论。虽然这项研究的直接影响是在位置理论，它也应该提供指导的问题类型和技术用于空间搜索行为的实证分析。

9320126 MILLER The proposed research address two major issues: (1) the relationships between spatial search and locational factors such as accessibility and (2) the effect of these relationships on market area structure. Both of these issues are fundamental to location theory. The project will develop probabilistic simulation models run on a supercomputer. The use of simulation models for this research provides the potential to include more realistic assumptions into location theory. In the first phase of the research the analysis will focus on the interactions between spatial search and spatial competition for the controlled case of the single searcher confronted with competing retail facilities. In the second phase retail stores will compete for a spatially dispersed, multiple customer base. Of particular interest is the effect of spatial search on the structure of market areas. Existing results in the literature suggest that search behavior can have complex, and unexpected, influences on facility patronage patterns. This research will have a significant impact on location theory through its novel approach to integrating models of search and competition. Although the immediate impact of this research is on location theory, it should also provide guidance for the types of questions and the techniques used for the empirical analysis of spatial search behavior.
