摘要 本文基于线性规划,建立重点行业间的资本要素优化模型,通过估算各重点行业的资本存量、劳动力人力资本及其产出弹性,得到各行业优化后的资本配置量和总产出,最后运用基于Fare-Primont指数的DEA方法测算各行业资本配置优化前后全要素生产率的变化。研究发现:重点行业间资本投入过度与资本投入不足现象并存,其中房地产业、交通运输仓储和邮政业以及水利环境和公共设施管理业资本要素投入过度,批发和零售业、制造业以及建筑业资本投入不足;矫正各行业资本要素配置扭曲后行业总产出和全要素生产率明显增大;矫正资本要素配置扭曲可以通过提高剩余混合效率进而提高全要素生产率效率,最终实现提高全要素生产率。 Based on linear programming,this paper establishes an optimization model of capital factors among key industries in China. By estimating the capital stock,labor human capital and output elasticity of each industry,the optimized capital allocation and total output of each industry can be obtained. Besides,using the DEA method based on the FarePrimont index,the paper calculates the changes of TFP before and after capital reallocation. It is found that excessive capital investment and insufficient capital investment coexist in China’s industries. Over-investment of capital factors in the real estate industry,the industry of transportation,storage and postal,the industry of water conservancy,environment and public facilities management,while underinvestment is in the wholesale and retail industry,the manufacturing industry and the construction industry. The total output and TFP of industries increased significantly after correcting the distortion of capital factors. Correcting the distortion of capital factors can improve total factor productivity by improving residual mix efficiency in TFP efficiency.
