摘要
本文研究大中型制造业的19个行业技术获取效率及其影响因素.首先对我国19个制造行业近10年的技术获取投入变化特征进行了分析,运用改进的DEA模型测度了我国19个制造行业技术获取效率,就影响技术获取效率的内部因素进行了计量分析.结果表明,制造业样本行业的技术对外依存度总体上呈减弱趋势,2004年前后,绝大部分样本行业递减幅度较大;技术对内依存度除少部分行业呈现一定趋势外,绝大部分行业无明显变化特征.在分析的12年中,绝大部分样本行业的技术获取并未获得有效产出,有效产出行业数占19个分析行业数的平均比例仅为23%,且呈区间特点,即1996—1997年、1998—2004年和2005—2007年3个时段有效行业数相对集中;部分行业保持持续的高效率.在影响技术获取效率的内部影响因素中,创新实力为关键影响因素.
The efficiency and influencing factors of technology acquisition of 19 large and medium-sized manufacturing industries are studied. First, the characteristics of technology acquisition input of 19 manufacturing industries in China during the past 10 years is analyzed. Then, the technology acquisition efficiency is measured using a modified DEA model. Finally, an econometric model is adopted to study the internal factors of the technology acquisition efficiency. The results show that the dependency on foreign technology of the sampling industries appears a descending trend on the whole, and most of them have a large range around 2004, whereas the dependency on domestic technology of most in- dustries has no apparent change except a few industries. In the 12 years discussed, the technology acquisition input in most sampling industries doesn＇t make effective output. The average ratio of effective industries to the 19 industries is only 23% , but the effective industries seem concentrated during 1996--1997, 1998--2004 and 2005--2007. Part of the industries keep a continuously high efficiency. Among all the internal influencing factors, innovation strength is the most important one.
