摘要
在全球进入数字技术驱动和引领的创新时代,信息通信技术(ICT)已经成为衡量一个国家数字贸易实力的重要标志。以2003—2022年中美ICT产品双边贸易数据为样本,基于空间模式可视化的分析方法,从微观和宏观角度分析了中美ICT产品贸易的特征和地位。首先,通过绘制贸易空间结构分析了中国向美国出口的ICT产品种类。其次,通过应用头尾断裂法和绘制希尔伯特曲线,对ICT产品分类的重要性进行了空间模式可视化呈现。结果表明:中美ICT产品双边贸易结构稳定,产品贸易变化程度均匀,存在贸易增长的空间和发展潜力。从产品看,“重量≤10kg的便携自动数据处理设备”在中美ICT产品贸易中表现出极其重要和稳定的特征。通过位序-规模法发现,中美ICT产品贸易呈现典型的重尾分布特征,78%的尾部产品对于保持和巩固ICT产品贸易结构的稳定性至关重要,22%的头部产品在中美贸易中扮演着重要的角色;从空间网格分布看,中美ICT产品贸易呈现出显著的正向空间溢出效应。
In the era of innovation driven and led by digital technology,information and communication technology(ICT)has become an important symbol to measure a country’s digital trade strength.Based on the data of bilateral trade of Sino-US ICT product trade from 2003 to 2022,this paper analyzes the characteristics and status of Sino-US ICT product trade from both micro and macro perspectives based on spatial pattern visualization.Firstly,this paper analyzes the types of ICT products exported from China to the United States by drawing the spatial structure of trade.Secondly,by applying the head-tailed breaks and drawing the Hilbert curve,this paper visualizes the importance of ICT product classification in spatial patterns.The results show that the bilateral trade structure of ICT products between China and the United States is stable,the change degree of product trade is even,and there is room for trade growth and development potential.From the perspective of products,“portable automatic data processing equipment weighing≤10kg”has shown extremely important and stable characteristics in the Sino-US ICT product trade.According to the rank size method,it is found that Sino-US ICT product trade presents a typical heavy-tailed distribution,78%of the tailed products are crucial for maintaining and consolidating the stability of the ICT product trade structure,and 22%of the top products play an important role in the Sino-US trade.From the perspective of spatial grid distribution,Sino-US ICT product trade presents a significant positive spatial spillover effect.
