摘要
The“social contract”is the most famous philosophical text of Zac Jacques Roussos,which was to influence the intellectual and political movement of the 18th century.By publishing the“social contract”or“Civil Law Principles”in 1762,Rousseau,presenting his theory of the state and seeking the foundation of civil society,attempts to expose the conditions of a stable and just state by putting freedom as a precondition for law and the common good must be lawful.A central place in its political theory is the concept of general will,which is in the general interest(otherwise the common good)and on which the idea of a favored constitutional state is based.We estimate approximately the size of the external economy by the method of the Contingent Valuation Method(CVM).The Contingent Valuation Method(CVM)is a survey-based technique,frequently used in Experimental Economics,especially useful for the valuation of non-market resources/goods/services,and cultural heritage objects(of aesthetic,historic,scientific,or social value),such as conservation of monumental remains and preservation of the physical and anthropogenic environment.
