辽宁省在东亚区域生产网络中的地位及作用

删掉从中间品生产以及垂直化分工生产的角度利用RCA指数和VSS指数,衡量和分析研究了辽宁省2010-2018年间在东亚区域生产网络中的地位。RCA指数表明,出口贸易中,辽宁省在传统制造业产品上具有竞争性,对于高附加值的产品较缺乏竞争优势。中间品贸易方面,辽宁省在东亚生产网络中以半成品以及零部件中间品的进出口为主,同时,从日本和韩国进口半成品占比高于其他经济体,反映了辽宁省主要参与了东亚区域生产网络的加工组装环节。细分行业看,辽宁省在电器机械及器材制造业、非金属矿物制品业等行业的垂直专业化程度较高,在通信设备、计算机及其他电子设备制造业等高附加值产品的垂直专业化相对较低。研究表明,辽宁省在东亚区域生产网络中,主要参与传统制造业的半成品和零部件的加工组装环节,其在区域产业链中的地位和自身产业结构有待进一步提升。

The Position and Function of Liaoning Province in East Asia Regional Production Network

RCA index shows that Liaoning Province is competitive in export trade in traditional manufacturing products and lacks competitive advantage in high value-added products.In terms of intermediate goods trade,Liaoning Province mainly imports and exports both semi-finished goods and parts and components in East Asia production network.At the same time,Japan and South Korea account for a higher proportion of imports of semi-finished goods than other economies.It reflects that Liaoning Province is mainly involved in the processing and assembly of the East Asia regional production network.Among subdivided industries,Liaoning Province has a high degree of vertical specialization in electrical machinery,equipment manufacturing industry and nonmetallic Mineral Products Industry while it is relatively low in high value-added products such as communications equipment,computers and other electronic equipment.The results show that Liaoning Province is mainly involved in the processing and assembly of semi-finished products and components in the traditional manufacturing industry in the East Asia regional production network.Our results show that the position of Liaoning Province in the regional industrial chain and its own industrial structure need to be further promoted.
