| 摘 要： | 从省际层面上对R&D投资的决定因素进行实证研究,主要关注通过外商直接投资(FDI)实现的国际技术转移、专利保护强度、经济增长以及人力资本积累和科学研究人员数量。通过极值边界分析(EBA)方法检验这些因素的稳健性和灵敏度。结果表明:高等教育和科研人员比例是对R&D强度具有积极影响的稳健决定因素,通过外商直接投资实现的外国技术流入和收入增长率对R&D投资无显著影响,专利保护强度对决定R&D投资具有稳健的积极影响。

| Abstract: | This paper investigates the determinants of R&D investment at the provincial level with an emphasis on the roles of international technology transfer through FDI,patent rights protection,and economic growth,in addition to the essentials of human capital accumulation and the number of scientific researchers. The Extreme-bounds-analysis( EBA) approach is applied to examine the robustness and sensitivity of these factors. The results of the EBA tests showed that tertiary education and the proportion of scientific researchers in a province were robust determinants that had positive effects on R&D intensity.Foreign technology inflows through FDI and the income growth rate are fragile determinants of R&D investment. Patent rights protection had a robust and positive impact on R&D intensity. |
