在中国加快建设贸易强国的背景下,数字化转型是区域贸易竞争力提升的重要途径。文章通过测度2011—2021年中国30个省份数字化转型水平和区域贸易竞争力,分析了两者的时空变化特征;然后基于经济政策不确定性的视角,利用空间杜宾模型检验了区域数字化转型对贸易竞争力的空间溢出效应。结果表明：①中国各区域数字化转型与贸易竞争力之间存在显著的空间相关性,并呈现出“高—高”集聚和“低—低”集聚的特点。②数字化转型不仅提升了本地的区域贸易竞争力,而且对近邻地区的贸易竞争力提升发挥了显著的空间溢出效应。③异质性检验表明,对于中国南部及GDP水平较高的地区,数字化转型对其周边区域的贸易竞争力的带动作用更明显。④在当前复杂多变的国际经济环境下,经济政策不确定性在数字化转型对区域贸易竞争力的影响中显示出负向的调节效应。最后,文章就依托数字赋能提升区域贸易竞争力提出了相应的对策建议。
In the context of China's accelerated construction of a trade power,digital transformation is an important way to enhance regional trade competitiveness. This paper measures the level of China's provincial digital transformation and the level of regional trade competitiveness in 2011-2021,and analyzes their spatio-temporal evolution characteristics. Then,based on the perspective of economic policy uncertainty,it uses the spatial Durbin model to test the spatial spillover effect of regional digital transformation on trade competitiveness. The results are as follows: 1) There is a significant spatial correlation between the digital transformation and the trade competitiveness in various regions of China,which shows the characteristics of "high-high" agglomeration and "low-low" agglomeration. 2) The digital transformation not only improves the local regional trade competitiveness,but also has a significant spatial spillover effect on the trade competitiveness of neighboring regions. 3) Heterogeneity test shows that digital transformation has a more obvious driving effect on its neighboring regions in southern China and regions with high GDP development level. 4) In the current complex and changeable international economic environment,economic policy uncertainty shows a negative moderating effect on the impact of digital transformation on regional trade competitiveness. At last,the article proposes the corresponding countermeasures and suggestions to enhance regional trade competitiveness through digital empowerment.
