【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 that affects the creation and dissemination of knowledge, which will affect the quality of enterprises' export products. Based on the dynamic panel data of 270 cities above the prefectural level in China, the effects of manufacturing agglomeration and service agglomeration on the quality of urban export products are investigated by using the system generalized moment method. It is found that the agglomeration of manufacturing industry can promote the quality of urban export products significantly, and the role of diversification agglomeration is more prominent than that of specialized agglomeration. The effect of service industry agglomeration on the quality of urban export products is not significant, but only producer services agglomeration has a significant positive impact on the quality of urban export products, and the effect of specialized agglomeration is more obvious than diversification agglomeration. However, the agglomeration of consumer service industry and public service industry has little effect on the quality of urban export products. We should actively guide enterprises to carry out reasonable spatial agglomeration, encourage diversified agglomeration in manufacturing agglomeration, and guide producer service industry and manufacturing industry to agglomeration together, so as to promote the quality improvement of enterprises' export products.
