| 简介： | This lecture, drawing on a rich body of research, focuses on how firms’ decisions regarding investment, exports, R&D, market entry, and exit influence market structure and industry dynamics. Taking the perspective of firm heterogeneity, it explores how demand, production costs, and entry costs can be integrated into a unified analytical framework, and discusses related issues of measurement and estimation. Furthermore, the lecture illustrates how this framework can be applied to various contexts—such as exports and R&D—to uncover the common underlying mechanisms of firm behavior. |
