Moving Towards a Green Future: GAMS, CGE Modeling, and Dual Carbon Goals
On April 23, the academic event “Moving towards a Green Future: China’s Sustainable Development Path under the Dual Carbon Goals” was successfully held at Renmin University of China. Sponsored by the School of Ecology and Environment of Renmin University and co-organized by Beijing Youwan Information Technology Co., Ltd., the event brought together over 50 distinguished participants from universities, research institutions, and enterprises.
With a focus on “Technology Empowering Policies, Innovation-Driven Transformation,” the event showcased how GAMS and CGE modeling are playing pivotal roles in guiding China’s sustainable development and achieving the national dual carbon goals.
Academic Excellence: From Theory to Practical Application
Lin Jie, a teacher jointly trained by China Agricultural University and Peking University, delivered an insightful lecture titled “CGE Model and GAMS Programming Basics.” His session broke down complex topics into three main modules:
Theoretical Foundation: Lin Jie explained the significance of the Constant Elasticity of Substitution (CES) production function in CGE modeling, emphasizing its critical role in simulating technological substitutions under fluctuating energy prices, a key concern under dual carbon strategies.
Data Compilation and Management: He outlined the meticulous process of building a Social Accounting Matrix (SAM), integrating multi-source data from national statistics, energy bureaus, and industry reports to ensure robust model foundations.
GAMS Programming in Action: Using real-world simulations like carbon tax impacts on the Beijing-Tianjin-Hebei region, Lin Jie demonstrated dynamic modeling in GAMS, showcasing variable definitions, equation scripting, and scenario-based solver execution.
Next-Generation Policy Tools: GPSAS and Intelligent Analysis Systems
Duan Meng, lecturer from the Institute of Quantitative and Technical Economics, Chinese Academy of Social Sciences, introduced cutting-edge advancements in policy simulation technology.
Global Policy Simulation Analysis System (GPSAS): Integrating multi-source big data with machine learning algorithms, GPSAS offers dynamic policy effect predictions, enhancing traditional static analysis methods.
Intelligent Analysis System: Duan showcased how natural language processing (NLP) enables automatic extraction of key policy parameters and simulates outcomes like carbon market dynamics with high precision and efficiency.
These innovations offer transformative tools for policymakers, enabling data-driven, real-time policy evaluations.
A Platform for Cross-Disciplinary Collaboration
The event featured an interdisciplinary dialogue among experts from:
- Chinese Academy of Social Sciences
- Institute of Automation, Chinese Academy of Sciences
- China Electronics Technology Group Corporation
- Chinese Academy of Fiscal Sciences
Discussions emphasized the critical need to integrate technical tools with policy design to achieve dual carbon goals. CGE models provide the necessary quantitative support for initiatives like carbon pricing, while systems like GPSAS help optimize market-based mechanisms such as carbon trading.
Participants praised the event as a “feast of intellectual exchange,” noting that it opened new academic horizons and inspired a fresh wave of interdisciplinary research initiatives.
