【摘要】 本文研究了在具有企业间生产网络的背景下，贸易自由化对绿色贸易的影响规模及机制。本文采用HITS算法创新地构建了中国企业的生产网络中心度指标数据，建立了包含中间品进口、最终品出口和污染排放的生产网络理论模型，并进行理论与实证分析。研究发现：贸易自由化有利于企业降低出口排放强度，实现绿色贸易的发展，并且该促进作用随着企业网络中心度的上升而不断增强，主要影响渠道来自规模效应、结构效应和技术效应。区分行业上游度来看，处于最上游位置行业的生产网络调节作用不明显，处于最下游位置行业的网络中心度对出口贸易自由化的调节作用较为显著，而居中行业的网络中心度对进口中间品贸易自由化的调节作用较为显著；区分地区来看，生产网络的调节作用对东部企业显著，而对中西部企业不显著。更多还原

【Abstract】 This study examines the impact of trade liberalization on green trade within inter-firm production networks and its mechanisms. Firstly, the HITS algorithm is employed to construct the production network centrality index of Chinese enterprises. Subsequently, a theoretical model of the production network, encompassing intermediate imports, final exports, and pollution emissions, is established, followed by theoretical and empirical analyses. The findings reveal that trade liberalization reduces export emission intensity and promotes green trade. Furthermore, this promotion effect escalates with increasing network centrality of enterprises. The primary channels of influence stem from scale, structural, and technological effects. From the perspective of industry upstream, the production network adjustment effect of the industry in the most upstream position is not obvious, the network centrality of the industry in the most downstream position has a significant adjustment effect on export trade liberalization, and the network centrality of the industry in the middle has a significant adjustment effect on import intermediate trade liberalization. From the perspective of different regions, the adjustment effect of production network is significant for enterprises in eastern China, but not significant for enterprises in central and western China.更多还原
