摘要
基于中国省际面板数据,并采用门槛回归技术,探究"互联网+"对创新溢出效率影响的异质动态效应。研究表明:"互联网+"显著驱动了区域创新效率,且这种积极影响存在一定的滞后效应;"互联网+"对区域创新效率的影响,呈现显著的正向且边际效率递增的动态特征,证实了"梅特卡夫法则"在区域创新系统中完全适用。"互联网+"的创新溢出效应存在显著的异质动态约束机制,经济发展、政府R&D资助调节下,均呈现正向且边际效率递增的动态特征;R&D强度、产业结构和技术引进约束下,均表现为正向U型动态特征;贸易开放度作用下,则具有正向N型动态特征。
Based on China’s inter-provincial panel data,and by using the threshold regression technology,the study explores the heterogeneous dynamic effects of Internet+’s on innovation spillover efficiency.The study indicates that:"Internet+"significantly drives regional innovation efficiency,and this positive impact has a certain lag effect;The impact of"Internet+"on regional innovation efficiency is characterized by significant positive and dynamic features of increasing marginal efficiency,confirming that"Metcalfe’s Law"is fully applicable in regional innovation systems;The innovation spillover effect of"Internet+"has a significant heterogeneous dynamic constraint mechanism.Under the economic development and government R&D funding adjustment,the dynamic characteristics of positive and marginal efficiency are presented.Under the constraints of industrial structure,R&D intensity and technology introduction,it indicates the positive U dynamic characteristics,with positive N dynamic characteristics under trade openness.
