基于三阶段DE A模型的我国医药制造业技术创新效率研究

摘要

采用可以剔除环境因素和随机误差影响的三阶段DEA模型对2000－2011年我国28个省、直辖市和自治区医药制造业的技术创新效率进行实证研究，结果表明我国医药制造业技术创新效率较低，并且创新效率值会受到环境因素的影响；创新效率值较低的原因主要是纯技术效率值的低下，另外规模效率的作用也不容忽视。各地区应加大对医药制造业技术创新的投入，提高规模效率，同时完善创新管理和制度体系，以效率为导向配置创新资源，最终达到提高综合效率的目的。%The three-stage Data Envelopment Analysis (DEA)model can eliminate the environmental effects and random error influ-ences.Based on this model,this paper conducts an empirical study on the technological innovation efficiency of pharmaceutical indus-try,focusing on 28 provinces,municipalities,and autonomous regions in China.The results show that first technological innovation ef-ficiency of Chinese pharmaceutical industry is relatively low,and innovation efficiency values are under the influence of environmental factors.Secondly,the reason for low innovation efficiency values is mainly low pure technological efficiency.Besides,the role of scale efficiency can't be ignored.Thus,each region should invest more in technological innovation so as to improve the scale efficiency in pharmaceutical manufacturing.Meanwhile,innovative management and institutional system should be perfected and efficiency-orien-ted distribution of innovation resources should be conducted,so as to ultimately achieve the goal of enhancing innovation efficiency val-ues.
