摘要
基于超效率共同边界函数测算了中国30个省(市)工业企业创新效率,从线性与非线性双重视角探讨了"互联网+"对区域工业企业创新效率的影响机制。研究发现:"互联网+"显著提升了区域工业企业创新效率,在缓解内生性问题之后,结论依然成立,同时这种影响具有显著的累积效应和滞后效应;从区域异质性看,"互联网+"对西部与中部地区的促进效用更为显著。基于动态面板门槛模型的结果表明,现阶段"互联网+"与区域工业企业创新效率存在边际效应递减的非线性关系。研究表明,"互联网+"不仅有助于提升区域工业企业创新效率,而且还有助于缩小地区间的创新效率差距。研究结果可为有效推进创新驱动发展战略及"互联网+"战略提供启示。
Based on the super-efficiency common boundary function,this paper calculates the innovation efficiency of industrial enterprises in 30 provinces(cities)in China,and discusses the influence mechanism of"internet+"on the innovation efficiency of regional industrial enterprises from linear and non-linear perspectives.The study finds that:"internet+"significantly promotes the innovation efficiency of regional industrial enterprises.The conclusion is still valid.after the alleviation of the endogenous problem.At the same time,the impact has obvious cumulative effect and lag effect.From the perspective of regional heterogeneity,"internet+"has a more significant promotion effect on the western and central regions.The results based on dynamic panel threshold model show that there is a nonlinear relationship with diminishing marginal effect between"internet+"and the innovation efficiency of regional industrial enterprises.The research shows that"internet+"not only helps to improve the innovation efficiency of regional industrial enterprises,but also helps to narrow the gap of innovation efficiency between regions.The research results can provide enlightenment for the effective promotion of the"innovation-driven development"strategy and the"internet+"strategy.
