摘要
本文运用反映信息摩擦的产品关联关键性指标,并结合社会网络分析方法,讨论了产品关联对中国差异化产品出口的影响效应。研究发现:①较高的产品关联度能够弱化信息摩擦,促进中国差异化产品出口;②在自由分类法下,基于产品关联的全球价值链活动有利于出口产品信息扩散与共享,在保守分类法下,产品分类的差异性将导致信息摩擦对中国出口的影响呈现“产品转移效应”;③在产品关联网络中,中间中心度对中国差异化产品出口更具促进作用,体现了更高的网络资源控制能力、更强的信息传递控制能力、更大的网络枢纽作用等越有利于产品出口;④传统引力模型中的地理距离与反映信息摩擦的产品关联均为影响当前国际贸易的重要因素。
The key indicators of product correlation reflecting information friction and social network analysis method was used to discuss the effect of product correlation on the export of differentiated products in China.The results show that higher product correlation degree can weaken information friction and promote the export of differentiated products in China.Under the liberal taxonomy,GVC production activities provide an important foundation for improving the efficiency of technology and information transfer.Under the conservative taxonomy,the difference of classification methods will lead to a“product transfer effect”on the impact of information friction on Chinese exports.Betweenness centrality has a more significant promoting effect on the export of differentiated products in China.It reflects the higher control ability of network resources,the stronger control ability of information transmission,and the greater hub function of network operation efficiency,which is more conducive to the export of products.Geographical distance in traditional gravity model and product correlation reflecting information friction are both important factors affecting current international trade.
