Abstract

閉鎖性水域における水質改善政策は, 汚濁物質の除去とともに, その流入抑制も併せて考える必要がある. 本稿は内陸・沿岸地域における各経済主体の水質に関わる行動と閉鎖性水域における汚濁物質の蓄積現象を捉えた応用一般均衡モデルを構築し, 閉鎖性水域の水質改善政策に対する地域間, 主体間の便益と費用の帰着構造を分析することにより, その経済的な評価を行う. さらに, 応用一般均衡モデルを制約条件, 主体毎の汚濁負荷削減量を政策変数, 社会的厚生の最大化を目的関数とした均衡制約付数理最適化問題 (MPEC) を定式化し, 遺伝的アルゴリズム (GA) を用いて, 目標水質水準を達成するために必要な各主体の汚濁負荷削減量を検討する.

The water quality improvement policies are urgently demanded in closed water areas today. There are, however, some conflicts of interests among economic agents, where application of comprehensive evaluation is required in order to check the feasibility of the policies. In this paper, we build the computable general equilibrium (CGE) model that catches the accumulation of the pollutant load, and analyze the incidence benefits induced by the water quality improvement policies in the closed water area. We formulate the mathematical programming with the equilibrium constraint that is CGE model and with the objective function that is the maximization of the social welfare. We distribute the reduction pollutant load in each regions and in each economic agents for water quality improvement by solving the MPEC with genetic algorithm (GA).
