本文采用最新测度服务进口技术复杂度的方法，并据此实证研究其对中国制造业效率提升的影响。计量检验结果表明：（1）从总体层面来看，提高服务进口技术复杂度能够显著促进我国制造业效率水平提升；（2）从服务贸易分部门来看，新兴服务贸易领域进口技术复杂度变化对我国制造业效率水平的影响，要强于传统服务贸易领域进口技术复杂度变化所产生的影响；（3）从制造业分部门来看，服务进口技术复杂度提升对资本密集型和技术密集型行业效率水平的影响，要甚于对传统劳动密集型行业的影响。提升制造业效率水平，作为中国制造业转型升级的重要内容和方向，不能脱离全球产业结构调整格局和全球分工体系。因此，进一步利用全球尤其是发达国家的产业优势，抓住全球服务贸易发展的重要契机，努力提升我国服务进口技术复杂度，以更好地服务于我国制造业转型升级的需要。

Based on the new method calculating sophistication of service import, we carry out empirical analysis about impacts of service import sophistication on China's manufacturing efficiency. The results show that: (1) generally speaking, improvement of service import sophistication can improve efficiency of China's manufacturing industry; (2) compared with traditional service import, service import in newly service sectors has much more impacts on efficiency of China's manufacturing industry; (3) sophistication of service import exerts more impacts on capital and technology-intensive manufacturing than labor-intensive manufacturing. Being one of most important aspects of China's manufacturing transformation; improvement of technology efficiency should not be isolated from global labor division. Therefore, to take advantage of global especially developed economies' competitive industries, and to grasp the important opportunities resulting from rapid development of global service trade, we should try to improve sophistication of service import to serve transformation of China's manufacturing.
