Cultural diversity and intellectual property protection

本研究研究文化产品进行国际贸易时的最优贸易和产业政策。在理论上，我们关注消费者跨期消费永恒性的动态效应的重要性，建立了一个可处理的具有垄断竞争的一般均衡模型。我们研究了均衡的性质，导出了商品和产业数量不足或过剩均衡对应的政策的精确形式，并给出了政府干预是合理的条件。在实证方面，我们探讨了文化商品所必需的知识产权（权利）的潜力，并回顾了政府在可贸易文化商品上培育民族品牌的战略方面。由于这一视角下的研究较少，我们对设计权商品行业进行了梳理，并对其市场结构进行了研究，揭示了一些潜在的问题。

This research studies optimal trade and industrial policies when cultural goods are traded internationally. Theoretically, we focus on the importance of the dynamic effect of consumers' inter-temporal consumption eternality and build a tractable general equilibrium model with monopolistic competition. We study the properties of the equilibria and derive the exact forms of policies corresponding to the equilibrium with either insufficient or excess number of goods and industries, and also show the conditions when the government interventions are justified. Empirically, we explore the potential of the intellectual property (right), which is essential to the cultural goods, and review its strategic aspects when the government may foster the national brand attached to her tradable cultural goods. Since only a quite few studies are done in this view, we shed right on the design-right goods industry and study its market structure and reveal some latent issues.
