Abstract

How much does trade in services affect regional production specialization and welfare? Using unique Canadian trade data, we document that the size of inter-provincial service trade is comparable to that of good trade, and that net exports of services are highly correlated with the value-added share of services across provinces. With a spatial model featuring domestic and international trade, we quantify the effects of service trade. Our results highlight that domestic service trade significantly promotes regional specialization, with heterogeneous welfare gains that reduce regional disparities. Conversely, international service trade generates more uniform welfare gains across provinces.

服务贸易、区域专业化与社会福利

服务贸易对区域生产专业化和福利的影响有多大？利用独特的加拿大贸易数据，我们证明了省际服务贸易的规模与商品贸易的规模相当，服务的净出口与各省间服务的增值份额高度相关。通过构建国内贸易与国际贸易的空间模型，量化了服务贸易的影响。我们的研究结果表明，国内服务贸易显著促进了区域专业化，异质性福利收益减少了区域差异。相反，国际服务贸易在各省之间产生的福利收益更加统一。
