Abstract
This study is made to consider the suitable management on the watershed based agricultural environmental loading which is not negligible compared with others sectors. In order to find out feasible linkage of economic development and environmental conservation in the watershed level, we quantify migration pathways of water pollutant and production inducement in sectoral, regional scales, to resolve their inter-sectoral and inter-regional interactions. Therefore watershed based inter-regional input-output tables are estimated and the embodied COD emission intensity is calculated. Furthermore we examine input structure change accompanied by environmentally conscious rice agriculture and discuss its effect and the significance of inter-regional trading on the watershed eco-efficiency andgoods production.
