本文比较了中国、美国和印度服务贸易的比较优势和贸易结构差异，并对三国要素积累对服务贸易出口增长的影响做了时间序列分析。分析发现，中国在劳动力资源密集的服务贸易部门具有比较优势，美国在一些人力资本密集型和物质资本密集型的现代服务部门具有比较优势，而印度仅在人力资本密集型的计算机与信息部门具有较强的比较优势。这一结论为三国间服务贸易比较优势的差异提供了一个基于要素因素的解释，从而引申出中国可以通过发展教育、加快人力资本积累来优化服务业内部结构，改善服务贸易收支的结论。
Based on the Heckscher-Ohlin model,this essay makes a comparison of the changing comparative advantages and structure of trade in services among China,America and India.With the help of time series analysis of the effect of accumulation of factors of production of the three countries on their respective exports in services,it is found that China has a comparative advantage in trade of labor-intensive services.By contrast,America has a comparative advantage in trade in services of human capital-intensive and physical capital-intensive sectors,and India only has a strong comparative advantage in computer and information sector with relatively high human capital-intensity.The above-mentioned conclusion provides a factor-based explanation of the differences of the comparative advantage of trade in services among the three countries,and it is implied that China should make great efforts to develop education and to accelerate the accumulation of human capital to optimize the structure of the service industry which plays an active role in improving the balance of trade in services.
