资源错配对全要素生产率的影响——基于总产出的核算框架

A Gross Output Accounting Framework for the Effect of Resource Misallocation on TFP

本文构建了一个基于总产出行业生产函数的增长核算框架,来衡量行业资源错配对总体经济的全要素生产率的影响。这一多部门模型基于分行业与总体相一致的全要素生产率测算框架,通过在行业资本和劳动投入上引入税收或补贴的做法来刻画行业层面的要素价格扭曲。一方面补充了资源错配文献中缺少的对中间投入作用的分析,另一方面进一步分析了生产率核算文献中资源配置效应的行业来源。本文也特别指出了在生产率测算和资源错配研究中普遍存在的基础数据不满足同质化要求的问题,并且在概念上说明了正确的产出和投入指数构建的方法论。最后,本文对资源错配研究中一直采用的固定收入份额进行了突破,通过在概念上利用投入产出序列来构建时变收入份额。

This paper proposes a gross output accounting framework that measures the effect of resource misallocation across sectors on TFP of overall economy. The framework is based on a multi-sector accounting framework which is consistent with the framework adopted by Jorgenson et al. （2005） revealing sector-specific factor price distortion in the form of adding taxes or subsidy to primary factor inputs （capital and labor） of sectors. This paper pays attention to the key importance of intermediate inputs which is neglected by the previous studies on resource misallocation, and further explores the industrial origin of resource allocation effect raised by the literatures about productivity analysis. This paper also highlights the issue prevailing in the productivity measurement and resource misallocation literature, which is that primary data can not meet the requirements of homogeneity and illustrates the correct methodology to construct the homogenous input indices. Finally, this paper adopts time variant income share of inputs rather than fixed income share, which is constructed using the sequence of input and output.
