考虑俱乐部异质性的制造业技术效率——基于潜类别随机前沿模型的研究

Heterogeneity of Technological Clubs and the Technology Efficiency of Manufacturing——Base on Latent Class Stochastic Frontier Model

本文利用中国2001～2007年28个制造业的面板数据,以各制造业的R&D作为类别的条件变量,通过建立潜类别随机前沿模型,考虑了俱乐部的异质性,从而分析我国制造业技术效率。结果表明,制造业存在两个异质性的俱乐部,它们使用不同的技术前沿,生产函数存在巨大差异;R&D越高的行业,处于俱乐部A的概率也越高,资本产出弹性和劳动力产出弹性不同是制造业分成两个俱乐部的主要原因。

Base on 2001--2007 panel data of 28 manufacturing industries , the manufacturing sector R ＆ D as the class condition variables, through the establishment of latent class stochastic frontier model, and taking into account the heterogeneity of technology clubs, this paper analysis the efficiency of our manufacturing technology. Empirical findings, there are two technol- ogy heterogeneity Club, the sector with higher R ＆ D, in the club the higher the probability of A. Different output elasticity of capital and labor output elasticity of the manufacturing sector is they are divided into two different clubs the main reason.
