中文摘要：

深化服务领域内的开放格局，不失为中国服务业发展的重要契机。在充分考虑知识源异质性前提下，通过定量比较，本文揭示了我国同主要发达国家双边服务贸易增长过程中的结构升级以及进口技术复杂度水平提升所体现“质”方面的改善特点。进一步借助转移份额分解法，本研究重点关注了进口技术复杂度提升对我国服务业发展的影响状况和作用机制，结果发现：服务贸易进口技术复杂度提升，主要通过促进我国各服务子行业劳动生产力水平提升所体现的组内增长效应，引致服务业增长；技术复杂度提升的结构改善作用不显著，制度因素仍然是服务业增长中结构效应和配置效应进一步释放的关键所在。

英文摘要：

Deepening opening - up of service can be regarded as an important opportunity for service development in China. Taking full account of heterogeneity of knowledge source and through quantitative comparison ,our study reveals apparent the upgrading of bilateral trade structure in service and improvement of technical complexity. With shift - share analysis and by focusing on impacts of technical complexity of service trade import on service development in China, the findings show that ： Through enhancing inter - group effect, the upgrading of technical complexity in service trade import results in apparent growth of service. Due to insignificant structural improvement through upgrading of technical complexity, policy improvement remains as the key to further releasing allocation effects and strstural effects.
