Development of Micro-Simulation Model to Evaluate Polices for Urban Goods Movement

为了在竞争日益激烈的商业环境中生存，单个公司必须不断适应新的和不断变化的环境。因此，企业的搬迁可以看作是适应的一种形式。此外，了解在企业选址决策中发挥关键作用的因素非常重要，以便确定吸引企业的最有效机制，从而保持健康的经济。在城市经济学中，相关的个体企业聚集在一起将获得一个企业所能获得的更低的生产成本和更大的市场份额等利益。企业在做出搬迁决策或地点选择决策时，并不是孤立地行动；相反，公司受到附近其他公司的影响。因此，本研究的主要贡献在于分析这些因素对单个企业区位选择和搬迁决策行为的影响，以便更好地理解关键因素。此外，空间效应对企业区位选择和搬迁行为的影响也应在研究过程中加以考虑。

In order to survive in an increasingly competitive business environment, individual firms must constantly adapt themselves to new and changing circumstances. Relocation of a firm, therefore, can be considered as a form of the adaptation. Besides, understanding the factors that play a key role in the decisions that businesses make on where to locate is very important in order to determine the most effective mechanisms to attract firms, and thereby maintain a healthy economy. In urban economics, the related individual firms which gather together will gain benefits such as lower cost of production and a larger market share that one firm can achieve. A firm, while making a relocation decision or location choice decision, does not act in isolation ; in contrast, firms are influenced by others who located nearby. The main contribution of this research, therefore, analyses the influence of these factors on location choice and relocation decision behavior of an individual firm in order to better understanding the key factors. In addition, how the spatial effect on the firm location choice and relocation behaviors should be considered carefully in the research process.
