科研创新提高了“一带一路”沿线国家的绿色全要素生产率吗

Does Basic Scientific Research Innovation Enhance Green TFP of “The Belt and Road” Countries

本文构建包含科研创新和绿色全要素生产率(TFP)的一个新经济增长模型,从理论层面阐述了基础性的科研创新对绿色TFP的影响机制。随后,利用"一带一路"沿线国家的跨国面板数据,在测算绿色TFP的基础上,实证检验科研创新是否提高了沿线国家的绿色TFP。研究结果表明:"一带一路"国家的绿色TFP整体呈缓慢增长态势;科研创新能够显著提升沿线国家的绿色TFP,影响路径主要为纯技术进步;科研创新对沿线亚洲国家绿色TFP的促进作用,仅通过提高纯技术进步实现;而对沿线欧洲国家的促进作用则通过纯技术进步和规模效率双重路径实现。支持沿线国家科研合作,倡导建立"一带一路"国际科学研究院,对"一带一路"沿线国家的经济发展有着重要意义。

By constructing a new model of economic growth, which synthesizes scientific research innovation and green TFP, this paper theoretically documents the influential mechanism of basic scientific research on green TFP. Base on the measurement of green TFP, the panel data of＂the Belt and Road＂countries is applied to empirically examine whether basic scientific research promotes green TFP. Results tell us that green TFP of ＂the Belt and Road＂ countries show a slow increasing trend. Moreover, scientific research innovation markedly enhances＂the Belt and Road＂countries＇ green TFP. Regional differences are also witnessed in influential paths; specifically, scientific research heightens Asian countries＇ green TFP only through pure technological progress while improves European countries＇ through both pure technological progress and scale efficiency. The conclusion supports international scientific research cooperation, advocates construction of＂the Belt and Road＂international scientific research center in order to realize communication, and has great implications on economic development of＂the Belt and Road＂countries.
