| 摘要: |
| 产业集聚是影响知识创造和传播的一种重要环境因素，会对企业出口产品质量产生影响。采用中国270个地级以上城市的动态面板数据，运用系统广义矩方法考察制造业集聚和服务业集聚对城市出口产品质量的影响，研究发现：制造业集聚对城市出口产品质量提升有显著的促进作用，且多样化集聚的作用比专业化集聚更突出；服务业（整体）集聚对城市出口产品质量的影响不显著，其中仅生产性服务业集聚对城市出口产品质量具有显著的正向影响，且专业化集聚的影响比多样化集聚更明显，而消费性服务业和公共服务业集聚对城市出口产品质量的影响不显著。应积极引导企业进行合理的空间集聚，在制造业集聚中鼓励多样化集聚，并引导生产性服务业与制造业共同集聚，以促进企业出口产品质量的提升。 |

| Abstract: |
| Industrial agglomeration is an important environmental factor to affect intellectual creation and spreading and to affect the quality of export products of the enterprises. By using dynamic panel data of 270 cities above prefectural level of China, this paper uses GMM method to examine the effect of manufacturing agglomeration and service industry agglomeration on the quality of export products and the research shows that manufacturing agglomeration has a significant boosting effect on promoting quality of urban export products, that the effect by diversified agglomeration is more obvious than specific agglomeration, that the effect of overall service industry agglomeration is not significant, but only producer service industry has significant impact on the quality of urban export products, that the effect of specialized agglomeration is more obvious than that of diversified agglomeration, however, the agglomeration of consumer service industry and public service industry has no obvious impact on the quality of urban export products. As a result, China should actively lead the enterprises to conduct rational spatial agglomeration, encourage diversified agglomeration in manufacturing industries, and lead the co-agglomeration of producer service industry and manufacturing industry so as to boost the quality of export products of the enterprises. |
