Pesticide pollution in coastal agricultural region was discussed with the new perspective and analytical ideals of environmental economics. Tong’an District which borders on Tong’an Bay, in Xiamen was chosen as the study area. The environmental costs incurred by applying pesticides in Tong’an District from July 1999 to June 2000 were evaluated by the analytical approaches of environmental economics combined with the Equilibrium Criterion (EQC) model, Soil Fugacity (Soilfug) model and Analytical Hierarchy Process (AHP). The result indicated that the ratio of environmental costs to the private costs was more than 0.80. Based on the results of the environmental cost analysis and the Soilfug model operation, the Linear Programming (LP) model was then applied to find the optimal cultivation structure of main crops, allowing for the maximum economic gain while restricting negative externalities in pesticide application. The issue about using pesticide product taxes to control pesticide pollution was also discussed.
