Abstract: This study intends to develop a decision making model that gives a solution of social problems such as widening economic gap between rural and urban regions and the corresponding environmental pollution. To revitalise regions that confront rural collapse, a framework of interregional management should be sought. A household investment system is taken up as a watershed-based management approach that enables to improve the water quality and realise sustainable agricultural activities. Multi-objective optimisation problems regarding regional long-term utilities are solved with a water pollutant emission model and an investment behavioural model. The proposed investment system is assessed in terms of interregional economic growth and environmental conservation. As a result, the investment system works well on an additional rural economic development and the watershed water quality conservation without interrupting regional economic growth.
