前沿生产函数在中国区域经济增长技术效率测算中的应用

The Estimation of China’s Provincial Technical Efficiency with Frontier Production Function

本文在对数型柯布-道格拉斯生产函数的基础上，运用随机前沿分析（Stochastic Frontier Analysis）模型和确定性的非参数前沿生产函数模型（Malmquist指数法）分别对我国改革开放以来25年间的技术效率变迁进行了测算。分析结果表明，我国经济增长过程中的技术效率改进并不明显，20世纪90年代中期后甚至出现了下滑的趋势，成为限制未来经济发展的隐患。

This paper estimated China＇s provincial technical efficiency change from 1979 -2004, by applying Stochastic Frontier Analysis as well as the Deterministic Parametric Frontier model （ Malmquist Index）. While a slight increase in average technical efficiency has been observed from the overall estimation result, a serious slowdown and decrease exists since mid 1990s. The study surfaces reflections on the sustainability of China＇s economic growth pattern and raises the question of whether the Independent Innovation could independently motivate the economy in the long run.
