中国已成为中等偏上收入国家近十年,但至今尚未跨越成为高收入国家。文章分析了九个国家的R&D投入状况及效应,探究R&D投入对规避中等收入陷阱的襄助效应,对R&D投入的襄助效应进行成因分析。结论表明：中国的R&D投入均衡水平较低,R&D人员强度远低于R D支出强度。大幅增加R&D研究人员强度,适度增加R&D支出强度,有利于提高R&D投入均衡水平,提高我国就业率和公共教育强度,进而提高其综合评价值,为我国成功迈进高收入国家的政策选择提供数据支撑。

China has been an upper-middle-income country for nearly a decade, and has not yet crossed over to become a high-income country. This paper analyzes the status and effect of R D investment in nine countries, explores the effect of R D investment on avoiding the middle-income trap, and analyzes the causes of the effect of R D investment. The conclusion shows that the equilibrium level of R D input in China is low, and the intensity of R D personnel is far lower than that of R D expenditure. A substantial increase in the intensity of R D researchers and a moderate increase in the intensity of R D expenditures are conducive to improving the balanced level of R D input, increasing the employment rate and the intensity of public education in China, and thereby improving its comprehensive evaluation value, providing experience and policy enlightenment for China to successfully enter the high-income countries.
