Given endowment and the technology of each country, we propose the conditions under which the matching mechanism is able to guarantee full participation and Pareto efficient provision, respectively, in the cases with certain and uncertain preference information. These conditions cannot only be adopted in international negotiation and cooperation, but also refines the theory of matching game. In comparative static analyses, we discover that: First, changes of initial stock of climate goods produce a wealth effect and the crowd-out effect is less than 1. Second, climate tax policies affect the supply and welfare of each country only when they produce wealth effects, and if tax revenue is transferred into climate goods with more advanced technology, they will produce positive wealth effects. Third, modifying matching plans dynamically and appropriately can urge countries to improve technology, and especially given a Pareto optimal mechanism, adjusting the matching plan to keep marginal rates of transformation unchanged as technology changes is still able to ensure full participation and efficient supply of climate goods.展开更多

Based on collection and collation of various concepts and explanations of ecotourism both at home and abroad, this paper reflects on the current connotations of ecotourism in terms of four aspects, namely, objects of ecotourism, ecotourists, nature of ecotourism as well as the relationship between ecotourism and communities. In-depth analysis was performed in an effort to revise the misinterpretation of ecotourism and provide implications for ecotourism initiatives. The main conclusions and fruits of this article include： 1） The objects of eeotourism should go beyond natural, pristine, or even only primitive natural areas to including cultural resources together with their natural context which also deserve preservation. 2） Tourism operators, compared to tourists, have more leverage and hence should shoulder more responsibilities for conservation. 3） Ecotourism should serve as a principle to guide tourism initiatives towards sustainability, rather than merely a special tour package. 4） The theoretic foundation was laid for community participation in ecotourism.展开更多
