文章基于1989~2014年APEC成员国(地区)的双边面板数据,将贸易成本的来源细分为可观测部分(地理阻碍、政策阻碍)和不可观测部分(制度阻碍、文化阻碍),运用改进的引力模型构造测算方程,综合测算了由可观测和不可观测因素造成的APEC国家(地区)双边贸易成本。研究发现:APEC成员国(地区)双边贸易成本总体呈现下降趋势;低贸易成本主要集中在东南亚、东北亚地区;高贸易成本集中于墨西哥、秘鲁两国;中国与APEC成员国(地区)双边贸易成本多为中等成本以下,呈现下降趋势,且低于APEC平均水平。
Based on the bilateral panel data of APEC member countries (regions) from 1989 to 2014, the paper divides the sources of trade costs into observable components (geohazards, policy impediments) and unobservable components (institutional impediments, cultural barriers), using improved The gravity model constructs the calculation equation, which comprehensively measures the bilateral trade costs of APEC countries and regions caused by observable and unobservable factors. The study finds that the bilateral trade costs of APEC members (regions) are on the whole decreasing; the low trade costs are mainly concentrated in Southeast Asia and Northeast Asia; the high trade costs are concentrated in Mexico and Peru; the bilateral trade between China and APEC member countries Costs are mostly below the medium cost, showing a downward trend, and below the average APEC.
