多区域投入产出(MRIO)方法融合了投入产出模型中最核心的完全投入与区域的概念,应用十分广泛。在生态环境领域,借助MRIO表中的地区、行业信息,可以有效地从需求端出发,研究环境要素等在区域与行业之间的贸易隐含流与足迹,讨论地区间的生态服务公平性问题。该文回顾了基于MRIO方法探讨国家间与国家内资源、环境等问题的应用研究,发现目前应用中国MRIO方法进行物质流问题的研究仍存在空白;分析了使用中国MRIO方法研究物质流问题可能的角度、方法上潜在的问题与解决思路。结果表明:通过研究省域间贸易隐含物质流以及省域资源足迹,可以为中国解决省域间资源和与资源相关的生态环境公平性问题提供政策支持,推进地区资源效率的发展,减少区域间生态包袱转移带来的影响。
The Multi-region Input-Output (MRIO) approach incorporates the most core concept of complete input and region in the IO model and is used in a wide range of applications. In the field of ecological environment, with the help of the regional and industry information in the MRIO table, we can effectively study the implied flow and footprint of trade and other environmental factors in the region and industry from the demand side and discuss the issue of the fairness of ecological services in different regions . This paper reviews the application of MRIO method to explore the resources and environment in countries and countries. It is found that there is still a gap in the research on material flow using MRIO method in China. The possible application of MRIO method to material flow problems in China is analyzed Perspectives, potential problems and solutions. The results show that by studying the implied material flow of provincial inter-regional trade and the footprint of provincial resources, it can provide policy support for China to solve the problems of provincial and inter-regional resources and resource-related ecological environment fairness, promote the development of regional resource efficiency and reduce the regional The impact of ecological burden transfer.
