本文使用2001-2013年197个经济体制成品数据和98个经济体服务贸易数据，测算了我国制成品和服务贸易的进口技术复杂度，在单位根检验和协整分析的基础上建立VAR模型，运用脉冲响应函数和方差分解分析就二者的经济增长效应做了实证比较研究。结果发现：我国制成品和服务贸易进口技术复杂度的提升均对经济增长显示出正向驱动效应；相比制成品而言，我国服务贸易进口技术复杂度的提升所展现出的经济增长效应更强，其对经济增长的贡献度更大。

This paper firstly calculates China’s manufactures’ and services’ import technological sophistication on the basis of 197 economies’ manufactures’ as well as 98 economies’ services’ data of 2001-2013，and after constructing a VAR model following unit root and co-integration tests，makes a comparative empirical analysis of their economic growth effects using impulse response and variance decomposition. The findings reveal that the increase of China’s manufactures’ and services’ import technological sophistication each has a positive driving effect on China’s economic growth; and compared with the manufactures’, the services’ import technological sophistication demonstrates an even stronger impact on as well as makes more contributions to China’s economic growth.
