Intermediate Microeconomics
本课程在原理课基础上，运用数学方法深入分析微观经济理论。主要内容包括：效用理论与消费者选择、生产理论与成本函数、完全竞争市场均衡、垄断与寡占理论、博弈论初步、一般均衡与福利经济学、信息经济学基础等。课程注重培养学生的数理分析能力，通过模型推导和案例分析，使学生能够运用高级微观经济理论分析复杂的经济现象。
Building on the principles course, this course uses mathematical methods to deepen the analysis of microeconomic theory. Topics include utility theory and consumer choice, production theory and cost functions, perfectly competitive market equilibrium, monopoly and oligopoly theory, introductory game theory, general equilibrium and welfare economics, and basics of information economics. The course emphasizes developing students' mathematical analytical skills.
选择一个寡头垄断行业（如电信、航空、网约车平台等），运用博弈论理论分析该行业中企业的竞争策略。构建一个简化的博弈模型，分析企业的定价策略、产量决策或产品差异化策略，求解纳什均衡。结合行业实际数据，验证模型结论，分析企业行为背后的战略逻辑，并探讨政府规制对市场竞争的影响。
Select an oligopolistic industry (e.g., telecommunications, airlines, ride-hailing platforms) and analyze firms' competitive strategies using game theory. Construct a simplified game model to analyze pricing strategies, output decisions, or product differentiation strategies, and solve for the Nash equilibrium. Validate model conclusions with real industry data.
