Can Economic Freedom Enhance International R&D Spillover:An Empirical Study of Transnational Panel Data

经济自由作为一项基础性制度安排势必影响国际R&D溢出效应的发挥。在构建理论模型基础上,运用105个国家(地区)跨国(地区)面板数据对经济自由制度、国际R&D溢出对技术进步的影响关系进行了实证分析。结论表明:通过货物、服务进口及FDI获取的国际R&D溢出对技术进步具有显著影响;而且经济自由在国际R&D溢出促进技术进步过程中具有正向促进作用;另外,经济自由与国际R&D溢出的协同交叉对技术进步的影响作用受到经济发展阶段或水平制约而表现出一定的差异性。
