金融危机后造纸产业技术创新效率变动实证研究——基于DEA-Malmquist指数法

Evaluation on Efficiency of Technology Innovation in Paper Industry——Using DEA-Malmquist Index

运用基于DEA的Malmquist指数法对经济危机后的造纸产业技术创新活动的全要素生产率、技术效率、技术进步的变动情况进行测算,并与木材加工业、通信设备制造业、有色金属冶炼业等行业进行横向比较,发现:2008年金融危机后,造纸产业技术创新活动的全要素生产率逐步恢复,但由于技术效率大幅下降,即使技术进步指数提高,后期的全要素生产率的恢复速度仍然趋缓。最后,对造纸产业技术创新效率变动的可能原因进行探讨。

This paper uses DEA-Malmquist Index to measure the total factor productivity,technical efficiency and technical progress index of paper industry＇s innovation in China after 2008 financial crisis.Compared with timber processing industry,communications equipment manufacturing industry and so on,this paper found that,after 2008 financial crisis,the total factor productivity of paper industrys innovation gradually recovery.However,because of substantial decline in technical efficiency,the rate of the total factor productivity recovery is slower in the latter,even if the technical progress index increases.Finally,explore the possible causes of the technological innovation efficiency change in paper industry.
