%X 摘要 通过引入单位要素成本指标，本文对佩特兰和勒文叟汉（Petrin and Levinsohn）的生产率分解模型进行了拓展，［1］得到了一个更为准确的资源重置效应。利用2000—2007年中国规模以上制造业企业数据，经过测算显示，技术进步和要素市场总扭曲是生产率增长的主要来源；样本期间资源重置对生产率增长的平均贡献仅有324%，且日渐式微。然而资源错配造成的福利损失却依旧占制造业增加值的近2663%。这表明，在现有体制下通过市场自发调节促进要素合理配置的空间已经耗尽，经济结构呈现出一定的“固化”倾向，进一步的资源重置应来自对现有经济结构的改革，以缓解资源错配。本文最后通过测算各地区的资源重置潜力，为区域结构优化提供了一个量化参考。<br>Abstract： We extend productivity decomposition model of Petrin et al by introducing unit factor cost，and obtain a more accurate reallocation effectEmpirical results calculated with Chinas abovescale industrial firm data (2000—2007) suggest that，during the sample period，technical effect and aggregate distortion explain most of aggregate productivity growth，while reallocation effect only contributes 324% and comes to near zeroHowever，welfare loss from misallocation accounts for about 2663% of manufacturing value addedThese evidences indicate that its next to impossible to improve allocation depends only on market mechanism under existing system，and the economic structure seems to be unchangeable Further reallocation should come from the reform of existing economic structure，which helps alleviate misallocationFinally，we compute the potential of reallocation in each region，and thus provide a quantitative reference for the optimization of regional structure
