摘　　要：借鉴新增长理论思想,构造一个用进出口内生技术进步增长模型,将进出口贸易对全要素生产率的促进作用分为进出口部门自身相对要素生产率的提高和对非进出口部门的技术外溢两类,考察比较货物贸易、服务贸易以及技术贸易对经济增长的影响。研究表明:货物贸易、服务贸易和技术贸易对非进出口部门均存在显著技术外溢;对外贸易技术扩散效应存在结构性差异,即技术贸易最大,服务贸易次之,货物贸易最小;货物贸易对自身要素生产率的提高并没有起到作用,而服务贸易和技术贸易均提升了自身部门的要素生产率,进而促进了经济增长。In this paper,the promotion of import and export on TFP is decomposed into their relative factor productivity and technology spillover,and the impact of commodity,service and technology trade on economic growth is compared through growth model of endogenous technological progress.The research shows that there is a significant spillover in commodity,service and technology trade,that there are structural differences in technology diffusion effect of foreign trade： technology diffusion effect of technology trade is maximum,the commodity is minimal,and the service is medium,and that commodity does not play a role in improving itself factor productivity,on the contrary,both service and technology trade enhance its own sector factor productivity to promote economic growth.
