数字经济、区域壁垒与统一大市场--来自长三角地区的证据

Digital Economy,Regional Barriers and Unified National Market--Evidence from the Yangtze River Delta Region

打破区域壁垒,促进要素在更大范围畅通流动,是构建全国统一大市场的前提。通过分析长三角地区的百度迁徙大数据,深入解析数字经济、区域壁垒与要素流动之间的相互作用机制。研究发现,数字经济对要素流动产生了双重直接影响:一方面,随着数字经济的发展,两地间的要素流动量增加,促进了市场统一,体现出连接效应;另一方面,要素更多地从数字经济落后地区流向发达地区,呈现出虹吸效应,阻碍了地区均衡发展。进一步分析指出,区域间的自然、人文和行政壁垒阻碍了数字经济连接效应的发挥,同时人文壁垒加剧了数字鸿沟带来的虹吸效应。

Breaking down regional barriers and facilitating the free flow of factors across a broader scope were prerequisites for building an unified national market.This paper delved into the interaction mechanisms among the digital economy,regional barriers,and factor mobility by analyzing the Baidu migration big data of the Yangtze River Delta region.The study found that,the digital economy had a dual direct impact on factor mobility.On one hand,as the digital economy expanded,the volume of factor flow between regions increased,fostering market integration and demonstrating a connective effect.On the other hand,factors tended to flow from digitally underdeveloped areas to advanced ones,exhibiting a siphoning effect that hampered balanced regional development.Further analysis pointed out that,natural,cultural,and administrative barriers among regions have hindered the realization of the connective effect facilitated by the digital economy.Additionally,cultural barriers exacerbated the siphoning effect induced by the digital divide.
