中国战略性新兴产业技术效率及其影响因素

Technological Efficiency and Impact Factors of China's Strategic Emerging Industries

本文使用2004-2011年中国7大战略性新兴产业46个样本行业的面板数据,采用随机前沿分析方法并构建超越对数生产函数模型,实证测度中国战略性新兴产业技术效率,并进一步检验其影响因素。研究发现：样本期间,我国战略性新兴产业生产活动存在技术无效率;样本行业技术效率值差异很大,极不平衡;在控制行业异质性后,行业平均企业规模、对外开放度及行业盈利能力对生产技术效率产生显著的正影响;国有产权比重对生产技术效率产生显著的负影响。

Based on the approach of Stochastic Frontier Analysis and adopting the model of Trans-log Production Function,the paper uses seven strategic emerging industries' panel data of 46 sample industries from 2004 to 2011to estimate the technological efficiency and test relevant impact factors of China's strategic emerging industries.We can draw the conclusions that there is technological inefficiency in the production activities in China's strategic emerging industries.Meanwhile,there is a significant difference among sample industries.Furthermore,after controlling the industry heterogeneity,we find that the average scale of enterprises and the economic openness and the profitability have significantly positive effect on technological efficiency.The proportion of state-owned property right in the industry has significantly negative effect on technological efficiency.
