A Decomposition of Total Factor Productivity Growth: The Case of Chinese Agricultural Growth before and after Reforms
提出一种在变系数前沿生产函数框架下将全要素生产率增长分解为技术进步和技术效率变化的方法，并用1970-87年中国省级农业数据实证分析，发现改革前后各省生产率增长差异显著。
Abstract Our objective in this paper is to explain a method to decompose the sources of total factor productivity (TFP) growth into technological progress and changes in technical efficiency within the framework of the varying coefficients frontier production function. An empirical application is demonstrated using the Chinese provincial‐level agricultural data covering the period 1970–87. The results indicate that TFP growth in the prereform period was negative in twenty out of twenty‐eight provinces and that it was positive in almost all provinces during the reform periods, while negative in sixteen out of twenty‐eight provinces in the postreform periods of 1984–87.
