国际研发投资与低收入国家自主创新能力

Effect of international R&D investment on capacity of independent innovation in low-income countries

国际研发投资通过三个渠道影响东道国自主创新能力,即东道国研发资本边际产出能力、研发投资水平及研发人员素质、研发全要素生产率。但不同类型的东道国拥有的过程机理并不一致。基于2000—2012年跨国研发数据,利用路径收敛设计方法,实证比较了上述过程机理在不同类型国家间的差异。研究发现,国际研发投资虽然有利于低收入国家R&D资本的边际产出能力,但总体上降低了其自主研发的投资水平和研发效率。未来应立足于国内市场提质升级、人力资本积累及企业家精神培育,以发挥国际研发投资提升低收入国家自主创新能力的正向溢出效应。

International R＆D investment could affect independent innovation capacity of low - income countries through three channels, namely marginal production capacity of R＆D capital, R＆D investment level and R＆D personnel quality and TFP of R＆D. But different types of host countries might have different process mechanisms. Based on Multinational R＆D data in 2000 - 2000, the paper has compared the process mechanism among different types countries using the method of path converged design. The results show that although international R＆D investment is beneficial to marginal product capacity of R＆D capital in low - income countries, but it could reduce their level of independent R＆D investment and innovation efficiency. The low - income countries should devote to upgrade domestic market, accumulate human capital and nurture entrepreneurial spirit in order to promote positive spillover effect of international R＆D investment and then improving independent innovation ability in the low - income countries in the future.
