本文提供了一个框架来理解垄断竞争模型中市场规模如何影响企业在产品差异化方面的投资。该理论提出，消费者对多样性的喜爱使他们对企业的产品差异化努力更加敏感，从而导致更大市场上的产品更加差异化。该框架还预测了贸易自由化对产品差异化的倒U型效应，从自给自足开始，贸易自由化导致产品差异化更强，但随着各国走向自由贸易，产品差异化减弱。
This paper provides a framework to understand how market size affects firms' investments in product differentiation in a model of monopolistic competition. The theory proposes that consumers' love of variety makes them more sensitive to product differentiation efforts by firms, which leads to more differentiated products in larger markets. The framework also predicts an inverted U -shaped effect of trade liberalization on product differentiation, with trade liberalization leading to more differentiated products when starting from autarky but then leading to less differentiated products as the countries approach free trade.
