主题：Which Japanese prefectures aregreenest? Insights from Input-output analysis (I-O) （日本哪些都道府县最环保？——基于输入输出分析（I-O）的见解）
主讲人：Prof. Narita Daiju（东京大学）
简介：Professor Narita is an environmental economist from the University of Tokyo. Before the current appointment, he worked at Hokkaido University, JICA (Japan International Cooperation Agency) Research Institute, the Kiel Institute for the World Economy (in Germany), and the Japanese Ministry of Education, Culture, Sport, Science and Technology (MEXT). He earned a PhD (sustainable development) from Columbia University, USA.His main research interest lies in the economics of climate change, in particular, theoretical and applied evaluations of economic costs on various aspects of climate change (including ocean acidification, damages of cyclones/typhoons, carbon dioxide capture and storage, and tipping-point risks). His research involves the application and examination of methodological frameworks of environmental economics, such as risk analysis and economic valuation of non-market ecosystem services, while it also deals with cross-disciplinary collaboration with natural scientists. He is engaged in research projects on environmental problems in Thailand, Kenya, Ethiopia, and Zambia under JICA and others.
成田教授是东京大学的环境经济学家。在进入东京大学之前，他曾在北海道大学、日本国际合作事业（JICA）研究所、基尔世界经济研究所（德国）和日本文部科学省工作。他在美国哥伦比亚大学获得可持续发展博士学位。他的主要研究兴趣在于气候变化经济学，特别是对气候变化各个方面的经济成本（包括海洋酸化、气旋/台风的破坏、二氧化碳捕获和储存以及临界点风险）的理论和应用评估。他的研究涉及环境经济学方法论框架的应用和审查，如非市场生态系统服务的风险分析和经济评估，同时还涉及与自然科学家的跨学科合作。他在JICA和其他机构的领导下，在泰国、肯尼亚、埃塞俄比亚和赞比亚从事环境问题研究项目。
摘要：Input-output analysis (I-O) is a form of macroeconomic analysis based on the interdependencies between different economic sectors or industries. I-O economic analysis was originally developed by Wassily Leontief (1906–1999), who later won the Nobel Memorial Prize in Economic Sciences for his work in this area. The foundation of I-O analysis involves input-output tables. Such tables include a series of rows and columns of data that quantify the supply chain for all sectors of an economy. Industries are listed in the headers of each row and each column. The data in each column corresponds to the level of inputs used in that industry's production function. This method is commonly used for estimating the impacts of positive or negative economic shocks and analyzing the ripple effects throughout an economy. During the talk, Prof. Narita will introduce Input-output analysis (I-O) and discuss recent developments Recent papers by Prof. Narita’s team published in the Journal of Cleaner Production and Sustainable Production and Consumption will be discussed further to understand the application of input–output analysis for the evaluation of environmental footprints of Japanese prefectures.. The talk will conclude with an overview of the Graduate Program on Environmental Sciences (GPES) at the University of Tokyo and a Overview of Management and Policy group at the university of Tokyo along with a brief overview to the Prof. Narita’s research group’s future research directions.
投入产出分析（I-O）是一种基于不同经济部门或行业之间相互依存关系的宏观经济分析形式。I-O经济分析最初由Wassily Leontief（1906–1999）开发，并因在这一领域的工作获得了诺贝尔经济科学纪念奖。投入产出分析的基础数据包括投入产出表，这些表格包括一系列行和列的数据，这些数据量化了一个经济体所有部门的供应链。各个行业被列示于每行和每列的标题中。每一列中的数据对应于该行业生产功能中使用的投入水平。这种方法通常用于估计正面或负面经济冲击的影响，并分析整个经济体的连锁反应。在演讲中，成田教授将介绍投入产出分析（I-O），并讨论最新进展。成田教授团队发表在《清洁生产与可持续生产与消费杂志》上的最新论文将被进一步讨论，以了解投入产出分析在日本都道府县环境足迹评估中的应用。演讲最后将概述东京大学环境科学研究生课程（GPES）和东京大学管理与政策小组的概况，并简要概述成田教授研究小组未来的研究方向。
