摘要

This study explores the impact of spillovers of public goods on industrial agglomeration based on the structure of the new economic geography. The model employed in this study is built on the Forslid and Ottaviano (2003) type of core-periphery model and the structure of taxation in Andersson and Forslid (2003). The endogenous provision of local public goods is explored for the cases of symmetric and asymmetric spillovers of the public goods. It is shown that the Nash equilibrium tax rate for public goods in each region causes a free-rider effect. Differing from the pattern of firms' distribution with Krugman (1991), symmetric distribution of firms does not emerge when the spillovers are asymmetric. Moreover, the spillover effect acts as a dispersion force for the distribution of mobile workers between two regions.

本文探討在新經濟地理架構下，公共財的外溢效果對產業聚集的影響。所採用的模型乃建立在Forslid and Ottaviano（2003）型式的核心邊陲模型以及Andersson and Forslid（2003）的課稅結構之基礎上。針對公共財的對稱與非對稱外溢效果，探討內生提供之地方公共財及其對產業聚集的影響。研究結果顯示，地方公共財的納許均衡税率會產生搭便車的效果。不同於Krugman（1991）的廠商分布型態，本研究得到：當外溢效果為非對稱時，廠商的對稱分布型態不會出現。而且，對於可移動勞工在兩區之分布，外溢效果扮演一個分散力量的角色。
