Abstract：Lake eutrophication as a result of economic growth, has become one of the most serious environment problems. This paper aims to explore the decision making information for coordinating economic growth and the reduction of nitrogen and phosphorus emissions in the Poyang Lake Watershed. An Environmental Computable General Equilibrium (ECGE) model based on the theory of mathematical optimization solution is introduced in this paper. On the basis of the 2008 provincial statistic data from yearbooks, an input-output table were created with indispensable parameters for this study. Following this, an inter-regional trade matrix was built to describe the regional trade and emissions among provinces. the coupled relationship between economic growth and emission reduction were explored and illustrated by applying the ECGE model. According to the estimates, a couple of strategies and one scenario for reducing the emission of nitrogen and phosphorus from those sectors with high emissions were identified. In addition, investment in scientific research and management also plays an important role in the reduction of nitrogen and phosphorus emissions at a regional level.
