中国ICT产品出口的时空格局及影响因素——基于“一带一路”沿线国家的研究

Spatial-temporal Pattern and Influencing Factors of Chinese ICT Product Export——Based on Study on Countries along the"Belt and Road"

分析2000—2021年中国对“一带一路”沿线国家ICT产品出口的时空格局,运用时空双固定的空间杜宾模型研究其主要影响因素的直接效应与空间溢出效应。结果发现:中国对“一带一路”沿线国家ICT产品出口额快速上升,计算机及相关产品、通信产品和电子元件是主要出口类别。东道国人均GDP、贸易开放度、经济稳定性和信息技术发展水平对中国ICT产品出口具有显著的正向影响,其中信息技术发展水平的空间溢出效应显著为正。异质性检验中,各因素对中低收入水平国家的影响较为明显,对ICT细分产业的影响有所差异。中国应攻克ICT产业短板,全面提升ICT产品核心竞争力,并重视影响因素的空间溢出效应以扩大ICT产品出口规模。

By analyzing the spatio-temporal pattern of China's ICT product exports to countries along the"Belt and Road"from 2000 to 2021,the model of spatial dubin is used to study the direct effect and spatial spillover effect of the main influencing factors.The results show that China's export value of ICT products to countries along the"Belt and Road"has risen rapidly,computers and related products,communications products and electronic components are the main export categories.The per capita GDP of host countries,trade openness,economic stability and the development level of information technology all have a significant positive impact on China's ICT exports,among which the spatial spillover effect of the development level of information technology is significantly positive.In the heterogeneity test,the influence of each factor on the low-and middle-income countries is more obvious,and the influence on the ICT subdivision industry is different.China should overcome the shortcomings of the ICT industry,comprehensively enhance the core competitiveness of ICT products,and pay attention to the space spillover effect of influencing factors to expand the export scale of ICT products.
