摘　　要：东亚因其迅速发展的国际生产网络而得到经济学界的广泛瞩目。本文在整理相关理论和实证文献的基础上,通过对人均收入水平的分析提出了东亚区域内广泛存在技术梯度差异的现实。作者根据Jones等人提出的国际垂直分割理论,建立增广引力模型,在区分零部件贸易和传统贸易的情况下,利用联合国贸易统计面板数据,对东亚垂直分工网络的技术结构进行了细致梳理。结果显示,近年来日本在核心部件上的作用有所下降,而四小龙实现了技术升级,作用得到较大的提升。作为东亚生产共享网络中的重要一极,中国同四小虎之间呈现出较强的互补性而非替代性。East Asia is much more highlighted than before because of its rapidly developing production network. Based on the research conducted by the former scholars, the author classifies the technology ladders according to difference of income level in East Asia. We augment the traditional gravity model according to international fragmentation theory by Jones et.al. Focused on the trade in parts and components, the paper analyzes the size, structure and changing of production sharing network in East Asia with the statistic data from UN-comtrade database. Our results demonstrate that, Japan′s leadership in kernel components is decreasing, while countries and regions like Korea and Hong Kong in China have climbed up to the higher technology position in a value chain in parts trade than before. Moreover, as an essential pole, China and the 'Four Tigers' are complementary instead of being substitute to each other in the East Asian production sharing network.
