基于DEA-Malmquist指数的装备制造业技术创新效率分析

Analysis on technological innovation efficiency of equipment manufacturing industry based on DEA-Malmquist Index

运用DEA-Malmquist指数法,分别从产业角度和时间角度对中国装备制造业全要素生产率进行分析,并通过聚类分析和逐步回归分别进行差异分析和影响因素分析。研究结果表明:从产业角度来看,仪器仪表及文化、办公用机械制造业的全要素生产率最高;从时间角度来看,装备制造业的全要素生产率和技术进步指数越来越趋于同一水平,体现出创新是促进产业发展的关键因素;市场结构对装备制造业全要素生产率的影响是最显著的。据此提出促进中国装备制造业创新发展的建议。

By applying DEA-Malmquist index method,the total factor productivity of the Chinese equipment manufacturing industry is analyzed from industrial and time perspectives,and the differences and influencing factors are analyzed by cluster analysis and stepwise regression.The results show that:from the industrial perspective,the total factor productivity of instrument,culture and office machinery manufacturing industries is the highest;from the time perspective,the total factor productivity and technology progress index of equipment manufacturing industry tend to be at the same level,which shows that the innovation is the key factor of promoting industrial development.The market structure has the most significant influence on the total factor productivity of equipment manufacturing industry.Suggestions are proposed accordingly of improving the innovation and development of the Chinese equipment manufacturing industry.
