The aim of this paper is to examine the relations of externality and locational conflict in public facilities. Generally locational conflicts related to public facilities in regional and urban area are come from the disagreement or clash about the distribution of external effects from the operation of public facilities. The incident of external effects and concomitant locational conflict pose considerable problems for the decision makers in spatial policy.
With the increase of distance from public facility, the distance-decay profile of externality field would be decline, but according to the perception of residents three kinds of response may be suggested: linear, exponential and polynomial profile. The scale, degree and type of locational conflict type depend upon residents' perception on disequilibrium of externality. The externality can be divided into positive and negative effects
Public facilities generating negative impacts often bring to stakeholder' strong opposition or violent behaviour because stakeholders feel their dissatisfaction in distributing cost/benefit. Positive impact facilities also result in conflict between regions or residents, but the degree of conflict is lower, because there is a little discrepancy of cost and benefit.
Consequently, the successful resolution and management of locational conflict depend on whether stakeholders can ensure the equilibrium of externality or not, and the community impacts including socioeconomic status, strategies, motivation.
