【摘要】：本文结合跨国研发投入、跨国技术转移、FDI、OFDI、贸易进口等多渠道国际研发资本技术溢出的空间效应,将线性结构的Coe-Helpman模型在空间维度拓展为非线性结构形式,构建了国际研发资本技术溢出的空间计量模型。在此基础上,运用中国省级面板数据实证分析国际研发资本技术溢出对中国绿色技术创新效率的影响,并对国际研发资本技术溢出的首次溢出、二次溢出效应进行分解,结果显示:(1)国际研发资本技术溢出模型存在显著的空间交互性效应,其空间效应不仅与被解释变量(绿色技术创新效率)相关,还与解释变量(各渠道的国际研发资本技术溢出)的空间关联效应相关,忽略空间效应的线性Coe-Helpman模型高估了国际研发资本技术溢出对绿色技术创新效率的影响。(2)国际研发资本比国内研发资本更好地促进了中国绿色技术创新效率,国际研发资本各渠道技术溢出效应有所不同,具体表现为:跨国研发投入、FDI研发资本、贸易进口三个渠道的研发资本技术溢出不仅促进了本区域绿色技术创新效率,二次溢出还促进了其他区域的效率,且二次溢出效应大于首次溢出。跨国技术转移首次溢出对本区域绿色技术进步产生了较为明显的促进作用,但二次溢出阻碍了其他区域绿色技术创新效率的提升。OFDI研发资本对国内投资产生了挤出效应,阻碍了绿色技术创新效率的提升。(3)国内研发资本阻碍了绿色技术创新效率的提高,说明中国企业绿色技术产业处于调整期,产业研发资本投入存在结构失衡、效率不高等问题。
[Abstract]:Considering the spatial effects of multi-channel international R & D capital spillovers, such as transnational R & D investment, transnational technology transfer, FDI,OFDI, trade and import, this paper extends the linear Coe-Helpman model into nonlinear structural form in spatial dimension. The spatial measurement model of international R & D capital spillover is constructed. On this basis, using provincial panel data of China to analyze the impact of international R & D capital spillover on China's green technology innovation efficiency, and to decompose the first spillover and secondary spillover effect of international R & D capital spillover. The results show that: (1) the international R & D capital spillover model has significant spatial interaction effect, and its spatial effect is not only related to the explained variables (green technology innovation efficiency); It is also related to the spatial correlation effect of explanatory variables (international R & D capital technology spillovers from various channels). The linear Coe-Helpman model neglecting spatial effects overestimates the impact of international R & D capital spillover on green technological innovation efficiency. (2) International R & D capital promotes China's green technological innovation efficiency better than domestic R & D capital. Different channels of international R & D capital have different technology spillover effects, which are manifested as follows: international R & D investment, FDI R & D capital, and trade import, which not only promote the efficiency of green technological innovation in the region, but also improve the efficiency of R & D capital spillover. The secondary spillover also promotes the efficiency of other regions, and the secondary spillover effect is greater than that of the first spillover. The first spillover of transnational technology transfer has obviously promoted the progress of green technology in the region, but the secondary spillover has hindered the improvement of the efficiency of green technology innovation in other regions. OFDI R & D capital has a crowding-out effect on domestic investment. (3) domestic R & D capital hinders the improvement of green technological innovation efficiency, which indicates that the green technology industry of Chinese enterprises is in the adjustment period, and the investment of industrial R & D capital is out of balance. Problems such as inefficiency.
