基于一般均衡理论推导加入了多边阻力改进的引力模型(Novy,2008),本文测算了1993～2010年我国与15个主要贸易伙伴之间的双边贸易成本,从而得出我国对外贸易成本的趋势表现及特点。主要包括:我国对外贸易成本在1993～2010年间呈下降趋势,从1.02的关税当量下降到0.63的关税当量,降幅为38.24%;将贸易伙伴以距离、收入、区域不同划分,发现我国与距离越远、收入越低的国家(地区)间的贸易成本越大,与东亚地区的对外贸易成本最低,其次是欧美国家,最后是“金砖”国家。
Based on the general equilibrium theory, we derive the gravity model with the added multilateral resistance (Novy, 2008). This paper estimates the bilateral trade costs between China and the 15 major trading partners from 1993 to 2010, and draws a conclusion that the trend of China’s foreign trade costs And features. Mainly include: the cost of China’s foreign trade declined from 1993 to 2010, from the customs equivalent of 1.02 to the tariff equivalent of 0.63, a decrease of 38.24%; the trading partners were divided by distance, income and region, and found that China and the distance Far from the low income countries (regions) the greater the cost of trade, with the lowest cost of foreign trade with East Asia, followed by Europe and the United States, and finally “BRIC” countries.
