摘要
基于2001—2014年86个主要国家的面板数据,利用社会网络分析法构建全球贸易网络,并从网络中心性、网络联系强度、网络异质性三个维度分析个体国家的网络特征与地位,以及对其出口技术复杂度的影响。研究发现:一国的贸易网络地位提高对其出口技术复杂度的升级具有显著的促进作用;随着一国的出口技术复杂度由条件分布的低端向高端攀升,贸易网络地位提高对出口技术复杂度的提升作用呈现弱化趋势;贸易自由化水平提升能够强化一国贸易网络中心性及异质性对出口技术复杂度的提升效应,但削弱了贸易网络联系强度的正向效应。研究结果对推动我国从贸易大国向贸易强国转变,实现对外贸易高质量发展具有一定的现实指导意义。
Based on the trade data of 86 major countries from 2001 to 2014, this paper uses the method of social network analysis (SNA) to construct a global trade network and then analyzes the network characteristics and status of individual countries from the perspectives of network centrality, strength and heterogeneity. On this basis, we empirically examines the impact of the status of a country's trade network on its export technology sophistication. The result indicates that the improvement of the status of a country’s trade network has a significant role in the upgrading of its export technology sophistication. With the conditional distribution of a country’s export technical sophistication from low-end to high-end, the upgrading effect of network status presents a trend of weakening. Furthermore, threshold regression analysis finds that an increase in the level of trade liberalization strengthens the upgrading effect of the network centrality and heterogeneity on its export technology sophistication, but weakens the positive effect of the strength. Therefore, China should actively transform its advantage of the status in the trade network into the advantage of export technology sophistication, materializing the transition of China from a large trading market to a large trading power, and realizing high-quality development of trade.
