中国电子信息产业技术效率趋势与空间收敛性研究——基于随机前沿生产函数的分析

Technical Efficiency of Electronic Information Industry Trends and Space Convergence Research in China--Based on Stochastic Frontier Production Function

采用超越对数的随机前沿生产函数法测算了我国电子信息产业技术效率总体及地区间的变动趋势,并检验了我国电子信息产业技术效率的空间收敛性特征。实证结果表明:(1)无论总体上还是地区内部,我国电子信息产业技术效率都呈逐步上升的趋势,但地区上升幅度存在空间差异;(2)我国电子信息产业技术效率具有显著的空间收敛趋势,各地区之间电子信息产业技术效率的差距在缩小。

This paper uses stochastic frontier production function method to measure the overall and interregional technical characteristics of （1） room efficiency technical Technical efficienc for differences in y of the of China＇s electronic information industry, efficiency of China＇s electronic information China＇s electronic information industry has region rise. （2） The technical efficiency of and examines the spatial convergence industry. Empirical results show that： an upward trend, however, there is China＇s electronic information industry has significant room for convergence of trends in electronic information industry, among the various regions, the technical efficiency gap is narrowing.
