Recently, the 2022 International Youth Leadership Finance Summit was hosted by the SAIF MF Program. More than 120 outstanding students from 24 top universities around the world gathered online to focus on ESG from the perspective of generation Z. Participating universities included: Tsinghua University, Peking University, Shanghai Jiao Tong University, Fudan University, Cornell University, London School of Economics and Political Science, University of Toronto, and the National University of Singapore, and many others. At the opening ceremony, Professor Chun Chang (Executive Dean, Professor of Finance, Huifu Chair Professor at SAIF) delivered a welcome speech. He said that through this international platform, the youth of today can swiftly exchange ideas with industry leaders and mature rapidly. The theme of this year's summit, "Exploring Solutions on ESG for a Better Future", attracted more than 1,000 applications from all over the world. Only 120 students were selected and they to re-form into teams in order to compete in the four-day live PK session and demonstrate their best solutions. Combining their professional expertise and interests, the participating teams chose business case companies in a wide range of markets, including: materials, new energy, consumer goods, automotive, etc. They focused on 23 companies, such as Contemporary Amperex Technology Co. Limited (CATL, a Chinese new energy technology company), Deliveroo (a British takeaway platform), JBS (a Brazilian meat producer), and International Petroleum Investment Co. (IPIC). They used professional knowledge and creativity to design ESG solutions for these companies, and analyzed the feasibility of the solutions for academic and industry experts. At the conclusion, Team Libru from Fudan University won first prize. They chose CATL as the business case company for their ESG solution and began their analysis from the perspective of the lithium battery cycle. Their perfect presentation and their calmness during the Q&A session won unanimous approval from the judges. At the summit, Professor Guangshao Tu (Member of the National Committee of CPPCC, Adjunct Professor of SJTU, Executive Director of SAIF Board) was invited to deliver a keynote speech (virtually) on "ESG and Sustainable Development of Enterprises". He pointed out that the trend of ESG investment was an important symbol of global economic and social development transformation. ESG practice and ESG investment were the two core parts of ESG development. Tu said that three major guiding mechanisms needed to be improved upon in order to promote ESG development, including: ESG practice for micro-entities at the government level, ESG investment in the real economy, and social capital by investment institutions. He also pointed out that ESG development needed: support of a theoretical system, institutional construction, main functions delineated, and an ecosystem. ESG investment can play five major facilitating roles in the sustainable development of enterprises, including: enhancing enterprise value, deepening capital function, optimizing asset structure, promoting enterprise governance, and improving disclosure quality. In addition to the twenty-three teams that were strictly selected to enter the summit, more than one hundred public judges from universities around the world were also invited to observe and participate in the summit. This not only built a platform for students to absorb cutting-edge knowledge and to dialogue with academic experts and industry leaders, but also actively promoted peer-to-peer exchange and learning opportunities among students from diverse backgrounds. During the Q&A session after the keynote speech, Qingyang Wang, a public judge from Nanjing University, asked Professor Guangshao Tu how a new energy supply could keep up with traditional energy based upon the goal of carbon neutrality, and whether it would lead to a deficiency in energy supply. She said that, through Professor Tu's speech and answers, she now deeply understood the logic behind management and control of carbon emissions (instead of just limiting energy consumption) in the practice of ESG.

Seminar on Supply Chain in Post-Epidemic Era Held by SAIF Think Tank
A closed seminar on "Changes, Opportunities and Strategies of Post-Epidemic Supply Chain"was held by our SAIF Think Tank recently at SAIF's Xuhui Campus. The seminar was presided over by Professor Xiaochun Liu (Associate Director of CAFR). Other experts in attendance include those from SAIF, the China Academy of Finance Research (CAFR), the Antai School of Economics and Management (ATSE) of SJTU, the China Financial Futures Exchange (CFFEX), and the Shanghai Institute of Futures and Derivatives (SHIFD). Professor Hong Chen (Professor of Management at SAIF) reported on "Analysis of the Influencing Factors of Carbon Emissions under the Emission Peak Target and Suggestions". Professor Chen analyzed the characteristics of China's carbon emission structure by comparing international carbon emission structures from different economies and their historical evolution. He analyzed the main influencing factors of carbon emissions by establishing macro-factor and industry-factor models and forecasted fossil energy consumption in the next 10 years. He put forward the necessity of maintaining a stable supply of traditional energy sources yet realizing the necessity of their gradual replacement by clean energy sources. Professor Chen also emphasized two points, the first being carbon footprint. We should not only focus on the direct generation of carbon emissions, but also on carbon emissions caused by consumption on the demand side. Secondly, energy storage technology is a troublesome bottleneck for the scale-up of clean energy. Professor Qigui Zhu (Secretary of the CPC SAIF Committee) reported on "Problems and Suggestions for the Development of China's Chip Industry"from the perspective of turning "crisis"into "opportunity". Professor Zhu discussed the chip industry development condition, both at home and abroad, then compared and analyzed the problems faced by the chip supply chain in China. He then suggested that we seize this good opportunity to promote industrial optimization and upgrading, and to accelerate the process of an independent and controllable chip industry. Specifically, he put forward five suggestions: (1) Insist on long-term investment; (2) Respect intellectual property rights and strengthen innovation protection; (3) Strengthen talent cultivation and attract to grow a senior engineering team; (4) Implement differentiated support policies and create a favorable industrial development environment; and lastly, (5) Enhance supply chain finance to help coordinate production and marketing. Professor Genyuan Zhong and Professor Mengdi Gu commented on the two reports, respectively, and gave high recognition to them. In the discussion session, participants shared their views on carbon emissions and the chip industry, and gave suggestions. These included: Feng Li (Professor of Accounting at SAIF, Associate Director ofCAFR, Co-Director of SAIFR), Professor Tan Wang (Professor of Finance, Academic Director of the MF Program), Professor Zhan Jiang (Term Professor, Academic Director and Executive Director of the EED Program), Professor Tzukuan Chiu, Mingliang Li (Senior Researcher at CAFR, Senior Legal Expert at CFFEX), Lei Hua (Deputy Dean at SHIFD), Ying Ma (Affiliated Professor at SAIF, Expert at CAFR), and Jie Hu (Professor of Practice at SAIF).

Professor Haizhou Huang Wins Sun Yefang Economic Science Award
On January 9th, 2022, the award ceremony of the 19th Sun Yefang Prize for Economic Science was held at the Chinese Academy of Social Sciences (CASS). Professor Haizhou Huang (Special-Term Professor of Finance at SAIF, Member of the Management Committee and Head of the Equity Business Department of CICC), together with Patrick Bolton (Professor of Economics and Finance at Columbia University) received the Prize for their publication The Capital Structure of Nations. The paper applies corporate finance theory to analyze national capital structures. Comparing the capital structures of China, the United States, Japan, and the United Kingdom, the paper argues that state-issued currency and treasury bonds issued in local currency are considered equity in the capital structure of the state, whereas treasury bonds issued in foreign currency are debt. The Sun Yefang Economic Science jury commended the publication for providing a fresh perspective for understanding monetary and fiscal policies in major economies. It also provided a unified micro-theoretical foundation for monetary economics, fiscal theory, and international finance. This paper also won the 2018 Pagano-Zechner Best Paper Award of the European Finance Association. The Sun Yefang Economic Science Award, named in memory of the eponymous Chinese economist, is one of the most prestigious awards in Economics in China. Founded in 1984, the award is given out biennially to honor economists who have made significant contributions. This year, the committee evaluated 115 books and 195 papers, ultimately giving awards for three of the books and four of the papers. Abstract When a nation can finance its investments via foreign-currency denominated debt or domestic-currency claims, what is the optimal capital structure for the nation? Building on the functions of fiat money as both medium of exchange and store of value (like corporate equity), the model connects monetary economics, fiscal theory, and international finance under a unified corporate finance perspective. With frictionless capital markets, both a Modigliani–Miller theorem for nations and the classical quantity theory of money hold true. With capital market frictions, a nation's optimal capital structure trades off inflation dilution costs and expected default costs on foreign-currency debt. Our framing focuses on the process by which new money claims enter the economy and the potential wealth redistribution costs of inflation.
