摘要
基于2011~2020年中国282个城市的面板数据,实证检验数字经济发展对城市制造业出口升级的影响,并分析其中介机制和空间溢出效应。结果表明:数字经济发展不仅能有效促进城市制造业出口升级,而且对邻近城市的制造业出口升级产生了正向空间溢出效应;技术创新和产业结构升级是数字经济驱动城市制造业出口升级的重要中介渠道;在东部城市、大城市和中心城市,数字经济对制造业出口升级的积极作用更明显。鉴于此,应加快数据要素市场培育和数字产业集群建设,发挥数字经济的辐射带动作用,加快关键技术的创新突破,促进产业结构高级化与合理化,以更好地推动制造业向全球价值链的中高端攀升。
Based on the panel data of 282 cities in China from 2011 to 2020,this paper empirically tests the impact of digital economy development on urban manufacturing export upgrading,and analyzes its intermediary mechanism and spatial spillover effect.The results show that the digital economy development can not only effectively promote the upgrading of urban manufacturing export,but also have a positive spatial spillover effect on the upgrading of adjacent cities'manufacturing export.Technological innovation and industrial structure upgrading are important intermediary channels for digital economy to drive urban manufacturing export upgrading.In eastern cities,large cities and central cities,the positive effect of digital economy on manufacturing export upgrading is more obvious.In view of this,we should accelerate the cultivation of data factor market and the construction of digital industry cluster,give full play to the radiation and driving role of digital economy,accelerate the innovation and breakthrough of key technologies,promote the optimization and rationalization of industrial structure,so as to better promote the manufacturing industry to climb to the middle and high end of the global value chain.
