| 摘 要： | 在经济全球化背景下，电子信息产业由于产业链绵长，片段化生产特征更为明显。现有研究主要集中于电子信息整体产业层面，缺乏对产业链视角下的电子信息产业动态和分工概念的思考。基于此，利用2006-2018年222个国家或地区的电子信息产业贸易往来数据，通过社会网络方法，探索电子信息产业上、中、下游代表性产品贸易网络的拓扑结构和主要国家的网络地位及格局演化。研究发现：电子信息产业贸易网络“核心-外围”结构明显；上游供应链网络呈现链式结构，网络密度稀疏，鲜有新的国家加入，中国在上游贸易网络中位置有所跃升，但仍未处于网络核心；中游和下游顶层网络呈现“扁平化”特征，在2006年中国已处于大部分产品贸易网络的关键节点位置，至2018年中国进一步跃升至网络核心。据此为提升中国电子信息产业在全球网络中地位，推动电子信息产业高质量发展提供有益的政策启示。

Structure characteristics and evolutionary pattern of strategic industrial trade network |
| |
| Abstract: | Under the background of economic globalization, the fragmentation production characteristics of electronic information industry are more obvious because of its long industrial chain. The existing research mainly focuses on the overall level of electronic information industry, and lacks of thinking about the dynamic and division concept of electronic information industry from the perspective of industrial chain. Based on this, using the electronic information trade data of 222 countries or regions from 2006 to 2018, using the method of social network research, this paper explores the topological structure of trade network of representative products in the upstream, midstream and downstream of the electronic information industrial chain, as well as the network status and pattern evolution of main countries. The results show that: the core periphery structure of electronic information trade network is obvious; The upstream supply chain network presents a chain structure with sparse network density and few new countries join in, China’s position in the upstream trade network has risen, but it is still not in the core of the network; The top-level network in the midstream and downstream is characterized by “flattening”; In 2006, China has been in the key position of most of the product trade network. By 2018, China has further risen to the core of the network. Based on this, it provides useful policy implications for improving the status of China’s electronic information industry in the global network and promoting the high-quality development of electronic information industry. |
