摘　　要：贸易效率是影响中国与RCEP伙伴国贸易增长的重要路径。借鉴新经济地理学的"3D"(density,distance,division)框架理论,在分析贸易效率影响机理的基础上,以RCEP成员国2000—2019年面板数据构建随机前沿引力模型,测算了中国与RCEP伙伴国的出口效率和进口效率,基于"一步法"非效率模型实证分析了密度、距离、分割对出口效率和进口效率的影响。研究结果表明:中国与RCEP伙伴国出口效率和进口效率存在异质性,进出口潜力巨大,其中进口潜力大于出口潜力。RCEP伙伴国经济密度提升有利于提高中国出口效率,但不利于提高进口效率,城镇化对中国进出口效率影响显著为负;交通基础设施对中国进出口效率具有显著正向影响,且在2008年金融危机后影响强度更大,通信基础设施有助于改善中国进出口效率;签订自由贸易协议对中国进出口效率具有正向影响,伙伴国政府效能可以显著提升中国出口效率,对进口效率的提升具有时滞效应。最后,针对研究结论,从提高密度、缩短距离和减少分割三个方面提出了相关政策建议。Trade efficiency is an important way to influence the trade growth between China and RCEP partners.Referring to the"3 D"(Density,Distance and Division)framework theory of new economic geography and on the basis of analyzing the influence mechanism of trade efficiency,this paper uses the panel data of 2000-2019 to build a Stochastic Frontier Gravity Model to measure the export efficiency and import efficiency of China and RCEP partners.And based on the"One-Step Method"Inefficiency Model,this paper empirically analyzes the effects of density,distance and segmentation on export efficiency and import efficiency.The results show that the export efficiency and import efficiency are heterogeneity between China and RCEP partner countries,and the import and export potential is huge,in which the import potential is greater than that of the export potential.The increase of economic density of RCEP partner countries is conducive to promoting China’s export efficiency,but not conducive to import efficiency.Urbanization has a significant negative impact on China’s import and export efficiency.Transportation infrastructure has a significantly positive impact on China’s import and export efficiency,and the impact is stronger after the 2008 financial crisis.Communication infrastructure helps to improve the efficiency of China’s import and export.Free trade agreements have a positive impact on China’s import and export efficiency,and the efficiency of partner governments can significantly promote China’s export efficiency and have a time-lag effect on import efficiency.Finally,the policy suggestions are put forward from the aspects of increasing the density,shorten the distance and reducing the division.
