[Study on the relative economic value of eco-environmental contributions].
Monetary valuation of environmental goods and services is one of necessary approaches for the sustainability of environmental and resource management. However, most studies on the economic valuation of regional and national environmental contributions were directly aggregated on the basis of micro analysis while the scale hierarchies of stakeholder collectivities were ignored. Market simulation is indispensable in the procedure of environmental valuation but potential demanders and suppliers were often assumed as individuals. In this paper, general concepts and functions of demand and supply for environmental goods and services were elucidated, hence the environmental economics logistic of public or quasi-public environmental good and service valuation was reviewed according to those concepts. Data and model constraints have restricted the validity of valuation case studies because of analysis of potential market bargainers' behaviors are usually partial and static. However, those imperfect studies can help decision-makers take policy choices and necessary for further research.
