改革以来中国经济是否存在快速的效率改进?

本文论证,在经济转型期间,我国国有经济存在产量与利润的双重目标,这背离了传统TFP份额增长核算法的微观基础。我们证明,此时传统TFP份额核算法低估了国有经济的真实TFP增长率,也低估了整体经济的TFP增长率;并且这种低估具有系统性,不会因数据质量问题以及生产函数的形式而改变。有鉴于此,我们推导了新的TFP核算公式。最后我们在一定假设下进行了实际测算:新方法测算的TFP年均增长率比传统方法测算的结果高1.8个百分点。

Has There been Rapid Productivity Growth in China During Its Reform Period?

Using the accounting approach developed by Klenow and Rodriguez-Clare (1997), we have decomposed China's economic growth since 1952 and obtained three main findings. Firstly, China's overall productivity has improved rapidly since the reform began in the late 1970s and accounted for nearly 70 percent of the output growth since 1978. Secondly, structural transformation and net productivity improvements are the main causes for this large contribution. Finally, the growth before 1978 was factor-driven, and productivity net of human capital and structural transformation decreased. Sensitivity analyses show that our findings are robust.
