摘　　要：自由贸易协定(FTA)网络持续演变,形成了复杂多样的网络关系。本文利用WTO深层协定数据库,基于复杂网络方法分析了FTA网络关系对FTA深化的影响,并探讨中国全球高标准自贸区网络的构建策略。研究发现,FTA网络关系能较好地解释两国FTA深化动因。FTA交叉网络效应反映了国家间的共同联系和合作基础,自主网络效应揭示了国家在全球网络中的战略位置与整体影响力。网络中心性越小的两国,邻居相似度对FTA深化的促进作用越显著。在条款类型方面,FTA网络关系对贸易深度自由化、经济一体化及WTO+领域的FTA深化解释力更强;在垂直深化方面,环境条款和创新条款的邻居相似度对FTA深化促进效应更强。基于全球样本分析基础上,中国情景下的FTA网络邻居相似度具有更强解释力,自贸区网络“提质”较“扩围”具有更高战略意义。The global economic recovery remains sluggish, exacerbated by intensifying trade and investment protectionism, which has resulted in mounting commercial frictions and conflicts.Meanwhile, more flexible Free Trade Agreements(FTAs) continue to proliferate, exhibiting distinct horizontal and vertical differentiation traits;these agreements have gradually emerged as the key driving force for trade liberalisation. WTO statistics indicate that as of December 2023, 595 cumulative WTOnotified FTAs remained in force globally. Given the “hub-and-spoke” structure of the global FTA network, two critical questions emerge:(1) Has this network's evolution significantly facilitated FTA deepening?(2) How does heterogeneity in network relations affect this deepening process amid increasingly refined and diversified FTA trends? While existing literature has partially explored regional trade liberalisation drivers, few quantitative studies adopt a network perspective to assess the relationship between FTA network structure and agreement deepening. This study addresses this gap by comprehensively measuring FTA network relations, thereby clarifying both the drivers of global FTA deepening and the intrinsic mechanisms behind horizontal and vertical FTA differentiation.This paper examines the impact of FTA network relations on FTA deepening using advanced social network analysis methods. It constructs relevant network indicators from the WTO deep trade agreements database. The empirical findings indicate that FTA network relations play a decisive role in FTA deepening trends among countries. Specifically, cross-network effects, represented by “neighbour similarity”, highlight the shared connections and foundations for cooperation between countries, while autonomous network effects-characterised by structural holes and eigenvector centrality-underscore nodal influence and strategic positioning within the global network. Notably, cross-network effects demonstrate stronger explanatory power than autonomous network effects, particul
