运用随机前沿分析技术(SFA),本文从产业层面详细研究了1996~2005年期间我国制造业各行业的技术效率水平以及产权、市场竞争、规模等因素对技术效率提高的贡献。结果显示,期间我国制造业各行业技术效率逐年提高,并且表现出一致的变动趋势;市场竞争程度的提高、国有企业的产权改革以及研发活动等对技术效率的提高起到了显著的积极作用,而规模因素对技术效率提升的作用并不明显,行业进入壁垒不利于产业技术效率的提高。
By using SFA, this paper studies in detail the technical efficiency of manufacturing industry in China from 1996 to 2005, as well as the contribution of factors such as property rights, market competition and scale to the improvement of technical efficiency. The results show that during the period, the technical efficiency of various manufacturing industries in our country increased year by year, and showed a consistent trend of change. The degree of market competition, property rights reform of state-owned enterprises and R & D activities played a significant positive role in improving technical efficiency. The effect of scale on the improvement of technical efficiency is not obvious, and barriers to entry into the industry are not conducive to the improvement of industrial technical efficiency.
