This paper proposes a new geo-environmental Impact index to quantify the implications and dynamics for a country to join in a regional cooperation for low carbon growth (LCG) in Asia. The index helps differentiating the countries according to risk dissemination and risk assimilation categories, which are so crucial in framing effective LCG policies. Empirical results reveal that under the proposed grand regional bloc comprising of 20 Asian countries, eight countries are identified as predominantly geo-environmental risk assimilators, one risk neutral, while the rest of the countries are identified as predominantly risk disseminators. Empirical results also show that synergy effect is evident in all the regional or sub-regional groupings. Sensitivity analysis indicates that the proposed grand regional bloc would yield higher possibility for reducing CO 2 emissions in the respective countries as compared to the actions taken by separate sub-regional groupings. The proposed model can also be used as an imperative tool in resolving the regional disputes under the climate change negotiations. A new Geo-Environmental Importance (GEI) index is estimated to quantify the impact of regional cooperation (RC) for low carbon green growth (LCG). Using the GEI the following research questions are answered: How much would it benefit a country if its partner countries could reduce the carbonization activities (i.e., emission and environmental degradation) to a certain level? and vice versa. What should be the costs and payoffs of the countries’ decisions under a game-theoretic approach? Under a regional cooperation framework, how the roles and liabilities of each country can be quantified? How effective the RC bloc would be in achieving overall CO 2 reduction in the region.

确定低碳增长区域合作国家：地缘环境影响指数

本文提出了一个新的地缘环境影响指数，以量化一个国家加入亚洲低碳增长区域合作 (LCG) 的影响和动态。该指数有助于根据风险传播和风险同化类别区分国家，这对于制定有效的 LCG 政策至关重要。实证结果显示，在拟议的由 20 个亚洲国家组成的大区域集团下，8 个国家被确定为主要地缘环境风险同化国，1 个风险中性国家，而其余国家则被确定为主要风险传播国。实证结果还表明，协同效应在所有区域或次区域分组中都很明显。敏感性分析表明，与单独的次区域集团采取的行动相比，拟议的大区域集团将产生更高的可能性来减少各自国家的 CO 2 排放。所提出的模型也可以作为解决气候变化谈判中区域争端的必要工具。估计新的地缘环境重要性 (GEI) 指数可量化区域合作 (RC) 对低碳绿色增长 (LCG) 的影响。使用 GEI 可以回答以下研究问题：如果一个国家的伙伴国家能够将碳化活动（即排放和环境退化）减少到一定程度，它会给一个国家带来多少好处？反之亦然。在博弈论方法下，国家决策的成本和收益应该是多少？在区域合作框架下，如何量化每个国家的作用和责任？RC 集团在该地区实现整体 CO 2 减排的效果如何。
