摘　　要：降低中国国内区域间的贸易成本,对于充分发挥国内市场潜力,推动构建以国内大循环为主体,国内国际双循环相互促进的新发展格局具有重要意义,而降低国内区域间的制度性贸易成本,更是促进国内大循环有效畅通的重要举措。本文通过构建一个多部门的一般均衡模型,发现中国国内贸易中的制度性贸易成本在国内总贸易成本中占比为21.7%,且制度性贸易成本的降低对贸易福利的改善来说效益十分明显,平均来看制度性贸易成本降低50%,会使中国整体福利水平提升5.9%,欠发达区域从制度性贸易成本的下降中获益最多。进一步地,各区域生产率差异化程度越高,即贸易弹性值越小,则制度性贸易成本的下降所带来的潜在收益也就越大;分部门来看,降低石油加工及炼焦业、农业、钢铁及有色金属加工冶炼业以及食品加工业部门的制度性贸易成本,将对中国的整体福利水平带来可观的效益。Based on the current dual pressures of the domestic and foreign economies and the need for China to deepen the reform and development stage,China strives to explore a new development pattern of"dual circulation"in which the domestic market is the main body,and the domestic and international markets promote each other,and reducing the cost of institutional trade between domestic regions is an important measure to promote the effective and smooth flow of the domestic market.Institutional trade costs include negotiation costs caused by information asymmetry and differences in local regulations,and policy costs caused by administrative intervention by local governments.They reflect irrational trade cost between regions due to factors such as local trade protection.Most of the existing estimates of domestic trade costs reflect the comprehensive value of domestic trade costs.This paper analyzes the institutional trade costs in domestic trade costs to more objectively measure the degree of inter-regional trade protection.First,we use the Head-Ries Index and the Input-output Table Data of China in 2002,2007 and 2012 to estimate the total trade cost between China’s regions and find that China’s domestic trade costs dropped by 3.9%from 2002 to 2007,while from 2007 to 2012,domestic trade costs increased by 6.8%.In the past ten years,the cost of domestic trade increased by 2.6%.Based on the estimation of total domestic trade cost,this paper draws on the method of Albrecht&Tombe(2016),and uses variables such as total trade cost and distance between provinces to make regressions,so as to separate the objective trade cost from the total trade cost,and the institutional trade cost is the residual item,that is,the cost of trade that cannot be explained by factors such as distance.Through the research of this paper,it is found that for China’s domestic trade,on average over a ten-year period,institutional trade costs account for 21.7%of the total trade costs.At the same time,this paper builds a multi-sector benefit evaluatio
