摘　　要：全国统一大市场是完善社会主义市场经济体制的重要保障,而各省市普遍存在的市场分割问题成为了制约国家经济发展的瓶颈与桎梏。从微观企业层面探讨市场分割对企业全要素生产率的影响,采用结构估计方法测算1998年-2008年中国制造业企业全要素生产率水平,并运用相对价格方差法计算29省市的市场分割程度。实证分析发现:市场分割会对企业全要素生产率产生负向影响;市场分割通过削弱规模经济效应、抑制创新研发以及过度保护国有企业等渠道降低企业全要素生产率;市场分割对非出口企业、东部地区企业及非国有企业全要素生产率的负向影响更大。为打破市场分割,提升企业全要素生产率,政府应加强宏观管理,打造现代服务型政府;激发微观主体活力,积极构建现代市场体系;完善法律法规,落实公平竞争审查制度。The national unified market is an essential guarantee for improving the socialist market economy system.However,market segmentation in various provinces and cities across China has emerged as constraint restricting economic development.The study explores the impact of market segmentation on enterprises'total factor productivity(TFP)from a micro-enterprise perspective.Using the structural estimation method,the study calculates the TFP of Chinese manufacturing enterprises from 1998 to 2008,and employs the relative price variance method to measure the degree of market segmentation in 29 provinces during the same period.The empirical results show that market segmentation has a negative impact on the TFP of enterprises.It reduces the TFP of enterprises by inhibiting economies of scale,suppressing innovation and R&D,and overprotecting state-owned enterprises.In addition,the negative impact of market segmentation is greater on the TFP of non-export enterprises,enterprises in the eastern region,and non-state-owned enterprises.To break market segmentation and enhance enterprise efficiency,the government should strengthen macro management,build a modern service-oriented government;stimulate the vitality of micro-subjects,and actively construct a modern market system;improve laws and regulations,and implement the fair competition review system.
