国际技术溢出与区域创新能力——基于知识产权保护视角的实证分析

International Technology Spillover and Regional Innovation Ability—— An Empirical Analysis Based on the Perspective of Intellectual Property Protection

文章通过2003-2013年中国省际面板数据,以知识产权保护为门槛变量,建立动态面板门槛回归模型,实证分析了对外贸易、FDI、OFDI等国际技术溢出渠道对区域创新能力影响的知识产权保护门限效应。结果表明,对外贸易、FDI、OFDI对国内区域创新能力的影响显著存在知识产权保护门限效应。当知识产权保护水平未跨过某一特定门槛值时,对外贸易对区域创新能力的促进作用相对较小,FDI、OFDI未能对创新能力产生显著的促进作用。当知识产权保护水平跨过门槛值后,对外贸易对区域创新能力的促进作用显著增大,外商直接投资、对外直接投资对区域创新能力产生了积极的促进作用。说明知识产权保护可以通过国际技术溢出渠道对区域创新能力产生正向作用。研究还表明我国大部分省份未跨过门槛值,处于低知识产权保护水平区域内。这意味着我国整体知识产权保护水平还较低,制约了国际技术溢出效应的产生。

Taken intellectual property protection as a threshold variable, this essay analysesthe influence of international technology spillover channels includ- ing the foreign trade, FDI and OFDIon regional innovation capabilityby using the dynamic panel threshold regression model with the interprovincial panel data from 2003 to 2013 in china. The results show that the effects of foreign trade, FDI and OFDI on innovation ability have a significant threshold effect based on intellectual property protection. When the intellectual property protection level does not exceed a certain threshold value, thepromotion effect of foreign trade on regional innovation ability is relatively small, FDI and OFDI fail to have sig- nificant effect on the innovation ability. When the intellectual property protection level exceeds the threshold value, the promotion effect has significantly increased. FDI and OFDI have significant positive effect on the innovation ability.This sug- gests that the intellectual property protection have positive effect on regional inno- vation capacity through the international technology spillover channels.The results also show that most provinces in china did not exceed the threshold value, and the intellectual property protection level is low.This indicatesthat the overall intel- lectual property rights protection level is also low in china, which restricts the in- temational technology soillover effect.
