国际经济发展(贸易部分)
Course Description
This module introduces international trade as a core dimension of economic development. It begins with why trade matters in the world economy, using the rise of trade shares, China's WTO entry, the US-China trade war, and the Belt and Road Initiative as motivating cases. The course then develops the main analytical questions of international trade: whether countries gain from trade, why they specialize, how trade patterns are shaped by size, distance, and barriers, and how economists use models such as comparative advantage, new trade theory, and gravity to interpret real-world outcomes. The final weeks connect theory to current policy.
Learning Goals
- Explain why international trade matters for growth, development, and contemporary global politics.
- Use comparative advantage and related trade models to describe gains from trade and distributional effects.
- Interpret trade patterns through the intuition of endowments, scale, distance, borders, and the gravity model.
- Evaluate major applied issues, especially trade policy, the US-China trade war, and trade-environment tensions.
