摘　　要：新发展格局是重塑我国社会分工结构的重要发展战略。内、外循环推动经济高质量发展的条件和机理差异明显。双循环结构要成为社会最优的分工结构,需满足系列边界条件。在满足这些条件的前提下,国内大循环能促进公共物品的层级跃迁,使广义全国公共物品得以提供,后者能通过提升微观主体的交易效率和生产效率,在宏观层面提高人均收入、实现劳动力要素的优化配置、促进产业结构转型。国际大循环虽然应按相对比较优势原则进行,但须区分正常和非正常两种情形。正常的外循环能促进国内劳动力的优化配置并缩小国内外的技术差距;非正常的外循环的典型作用是倒逼国内改革,以改革的红利弥补外部贸易扭曲的损失。China's new development paradigm features dual circulation,in which both domestic market and overseas one reinforces each other,with the domestic one as the mainstay.This is an important economic development path and strategy for China in the new stage of development.This paper focuses on the characteristics of China's domestic circulation from the perspective of China's domestic unified large market construction.The construction of a national unified big market involves six areas,namely,“unified basic market institutions and rules,high standard connected market facilities,unified factor and resource markets,unified commodity and service markets,unified market supervision and fairness,and regulation of improper market competition and market intervention”.The unifications involved in these fields were previously limited to small areas and were public goods in small scope.The essence of the construction of the domestic unified market is to break down the regional barriers and eliminate the administrative economy through top-level design so that regional public goods can be transformed into generalized national public goods.The domestic circulation has two functions:improving transaction efficiency and production efficiency.This paper focuses on the following question:what impacts will these two functions have on China's internal and external circulation?In this paper,the new development paradigm,especially the two functions,is viewed from the perspective of the division of labor.The two functions of dual circulation are analyzed endogenously within the framework of ultra-marginal analysis.A series of boundary conditions must be satisfied for the dual circulation structure to be the optimal structure among many structures of divisions of labor.This paper draws the following conclusions:First,any kind of division of labor structure has its critical conditions to be satisfied.There is no optimal division of labor structure in every case.For a certain division of labor structure to become the socially optimal divis
