摘要
为了进一步了解我国单一区域内创新型企业的创新活动,基于大型企业和中小型企业的视角,以安徽省340家省级创新型企业为例,利用随机前沿方法(stochastic frontier approach,SFA)对这些企业的创新效率及其影响因素进行对比分析.结果表明,这些企业的创新效率处于中等水平,大型与中小型创新型企业的创新效率在同一水平上,部分中小型的企业创新能力较强.在影响因素方面,企业规模对中小型创新型企业有着正向影响,而对大型企业的创新效率的影响作用不显著.政府经费支持对创新型企业的创新效率有负向影响,而税费减免对其则有正向影响.大型企业与中小型企业的创新效率提升途径存在一定差别.
In order to further understand the innovation activities in innovative enterprises within a region in China,from the perspective of large sized and small-medium sized enterprises(SMEs),the innovation efficiency of these enterprises and its influence factors were analyzed employing the data from 340 innovative enterprises in Anhui Province as a sample and the stochastic frontier approach(SFA).The results show that the innovation efficiency of these enterprises is at the medium level;the innovationefficiency of the large sized enterprises is at the same level as the SMEs and some of the SMEs have strong ability of innovation.As to the influencing factors,it is found that firm size has a positive impact on the innovation efficiency of the SMEs,but no influence on that of large sized enterprises.The R&D subsidies from the government have a negative impact on the innovative enterprises’innovation efficiency,while tax breaks have a positive impact on it.Different approaches are to be adopted for large sized enterprises to improve innovation efficiency from those for small-medium sized enterprises.
