Research Scholar in Management, Economics, Public Policy, and Information Science
My name is Long Guo. I am responsible for collaborative research in partnership with government ministries and agencies, as well as organizations such as the Japan Science and Technology Agency (JST), the New Energy and Industrial Technology Development Organization (NEDO), and the Japan Agency for Medical Research and Development (AMED), to address a wide range of research challenges.

Bio
I am Guo Long, currently a doctoral student at the Graduate School of International Public Policy, Osaka University.
My research lies at the intersection of economics, public policy, and international development, with a particular emphasis on development economics. I specialize in development economics and international economics, conducting research to identify the root causes of poverty in developing countries and to explore effective policies for sustainable economic growth. As globalization advances, the impact of one nation’s policies on others can no longer be overlooked. Thus, economic development in developing countries increasingly requires international policy coordination and the adjustment of national interests.
For example, promoting industrialization in developing countries often results in higher greenhouse gas emissions. In such cases, cooperative approaches may be proposed—such as those exemplified by the Clean Development Mechanism (CDM), where advanced countries with emission reduction obligations support the introduction of low-emission technologies, enabling developing countries to pursue industrialization while mitigating environmental impacts.
My research seeks to uncover the driving forces behind aggregate variables such as GDP, consumption, inflation, trade, and exchange rates. Within the fields of macroeconomics and international economics, I analyze how these aggregates are determined, beginning with the behavior of households, firms, governments, and financial institutions.
I focus particularly on the intersection of macroeconomics—with an emphasis on business cycles and economic growth—and international economics, which addresses trade and international finance. My work integrates both theoretical and empirical analyses of macroeconomics, international trade, monetary policy, and economic development.
I am a researcher who integrates management studies, economics, international public policy, and information science, pursuing an interdisciplinary approach with economics as the core discipline.
In my research to date, I have applied theoretical modeling and statistical analysis in economics, combined with data analytics and quantitative finance methodologies, to examine macroeconomic fluctuations and the risk structures of financial markets. From the perspective of international public policy, I have also analyzed global issues such as educational inequality, development aid, and trade and migration policies, conducting empirical evaluations of their impacts.
Furthermore, I have expanded my focus to themes related to the SDGs and sustainable growth, quantitatively evaluating the interactions between environmental policies, gender equality, education, and economic development. In addition, I am advancing the integration of economics with information science by employing AI, network science, and computational social science to design new models for economic analysis, develop frameworks for cybersecurity and economic incentives, and apply game theory and complex network analysis to resource allocation.
In recent years, I have also emphasized information security within the field of information science, engaging in research on malware detection, cyberattack defense models, and AI-driven dynamic risk management. At the same time, I have extended my work to data analysis in the healthcare domain, applying statistical methods to patient data, epidemiological information, and healthcare resource allocation, with the aim of improving medical efficiency and addressing health disparities.
By combining management studies, economics, public policy, information science, information security, and healthcare data analytics, I seek to go beyond the boundaries of traditional disciplines and contribute new academic insights that can address pressing challenges in both the digital and global society.
From My Blog
I am pursuing a career that applies statistics and econometrics, and I am currently engaged in research under the Innovative Low Food Loss Co-Creation Hub Program (Food DX). My work relates to the project “Empirical Analysis of Vertical Spillovers and Induced Innovation in International Production Networks under Product Safety Regulations”, with a specific focus on evaluating the costs and benefits of introducing food loss reduction technologies into international supply chains.
Globally, it is estimated that about one-third of food that is still edible is discarded, making food loss a pressing issue. In my study, I focused on bananas and applied a conjoint analysis, an econometric method, to measure consumers’ willingness to pay a price premium for products from companies that actively work to reduce food loss. The results revealed that while consumers do show positive evaluation, the magnitude of this premium is relatively limited, indicating that public awareness of food loss in Japan is not yet particularly strong.
A high consumer price premium would provide economic incentives for producers and suppliers, thereby encouraging food loss reduction across the entire supply chain. Looking ahead, I plan to expand my research to include not only consumers but also producers and suppliers, analyzing the comprehensive costs and benefits of adopting food loss reduction technologies. My aim is to assess whether a sustainable system can emerge across supply chains even without direct government intervention.
This research is conducted in collaboration with the Graduate School of Engineering at Osaka University, combining the strengths of economics and engineering, particularly biotechnology. Engineering researchers contribute in-depth expertise in specific technologies such as freshness preservation, while economics provides a broader perspective on how these technologies affect supply chains and consumer evaluation. I believe this interdisciplinary collaboration has produced highly positive outcomes.
In the field of development economics, which is my area of specialization, research themes are diverse, reflecting the complex challenges faced by developing countries. Examples include the economic impact of refugees on host-country labor markets, the effects of natural disasters and global warming on poverty, and the influence of China’s environmental policies on its economic performance. Through such studies, I seek to explore economic prescriptions for addressing the urgent challenges faced by developing nations.
