碩士 === 南華大學 === 環境管理研究所 === 90 === The purpose of this thesis is to determine the optimal pollution fee based on the objective of minimized social welfare. The results of the analysis in this thesis provide a broad understanding of policy reforms and serve as a guideline for policy planner to formulate environmental policy. The theoretical analysis conclude results: 1. The optimal pollution charge has close relationship with the function of the society’s cost and the reducing pollution cost . 2. The optimal water price determined by the principle of social welfare maximization may become negative. 3. An increase in impurity content in raw water or pollutant concentration at household discharge may lad to rise-up of optimal water price and optimal consumption quantity . A rise-up of abatement cost function, social cost, and production cost may lead to an increase in optimal water price and optimal consumption * . Through the presentation of the taxation model, the policy planner can encourage the compound housing community to take some measures in mitigating pollution emission with the achievement of maximized social welfare. In brief, the contributions of this thesis at least contains: 1. The effects of the tax rate and water price on social welfare can the demonstrated substantially by this taxation model. 2. The properties of the parameter in this model are analyzed. As a consequence, the results can serve as references for policy making.
