摘　　要：本文基于ADB-MRIO增加值数据和WTO-RTA贸易协定数据,利用社会网络分析法构建区域贸易协定(RTA)网络中心地位指标,实证检验了一国RTA网络地位对国内增加值出口的影响。研究发现:一国通过嵌入密集而广泛的RTA “邻居网络”占据中心地位,能够促进国内增加值出口增长;RTA网络中心效应主要集中于发展中经济体的出口增长,具有明显的区域排他性和地理临近偏好;区分行业异质性发现,中心效应主要促进了中间品投入程度较高的制造业和运输服务业国内增加值出口。为此,政策上一是要注重选择高质量的贸易伙伴;二是注重邻近国家在自贸区的优先性;三是注重增加值出口结构的调整。Based on the ADB-MRIO value added data and the WTO-RTA trade agreement data,this paper constructs the regional trade agreement(RTA) network central status index through social network analysis methods,and empirically tests the impact of a country’s RTA network status on domestic value-added exports.The study found that a country can promote the growth of domestic value-added exports by embedding a dense and extensive RTA "neighbor network",and the RTA network centrality effect is mainly concentrated in the export growth of developing economies,along with obvious regional exclusivity and geographical proximity preferences.By distinguishing industry heterogeneity,the paper found that the centrality effect mainly promotes the domestic value-added exports of manufacturing and transportation services with a high degree of intermediate inputs.Therefore,relevant policies should take the following things into consideration:the selection of high-quality trading partners,the priority of neighboring countries in the free trade zone,and the adjustment of the value-added export structure.
