本文建立了一个考虑服务业重要特征的产业内服务贸易模型。我们发现，当贸易前国内市场自由化程度有限时，相同经济体之间的服务贸易自由化具有福利增强效应。无论贸易自由化的程度和供应方式如何，这一点都是成立的。但是，如果贸易前的环境是自由进入均衡，那么服务贸易自由化就不一定是福利改善。贸易自由化程度越高，供给方式越是跨境，福利越高。在我们的模型中，贸易的收益来自于服务质量的提高--消费者理想的品种与企业产品特异性之间的更好匹配。本文还探讨了服务贸易供给模式的含义。
This paper develops an intra-industry service trade model taking into account important features of services. We find that service trade liberalization between identical economies is welfare enhancing when the pre-trade domestic market liberalization is limited. This holds regardless of the degree of trade liberalization and of the mode of supply. However, if the pre-trade environment is characterized by a free-entry equilibrium, then service trade liberalization is not necessarily welfare improving. It is welfare enhancing if the trade liberalization is full and the mode of supply is cross-border. The gain from trade in our model comes from the improvement in service quality - better matching between consumers' ideal varieties and firms' product specificity. The implications for the mode of supply in service trade are also explored.
