笔者利用空间自相关Moran’I指数及空间计量模型,结合改进的Romer-Jones型知识生产函数,对我国省际知识的溢出效应进行空间计量经济分析。分析结果显示:R&D投入、R&D人员、知识存量以及国外技术引进对新知识的生产具有正向贡献率,各因素贡献程度不一,其中知识存量的平均贡献率最大(0.460)。我国省际新知识的生产具有空间溢出效应,周边地区的新知识生产平均每增长1%,本地区新知识生产将平均增加0.469%。
Based on the spatial autocorrelation Moran’I index and the spatial econometrics model, the author combines the improved Romer-Jones knowledge production function to do spatial econometric analysis on the spillover effect of interprovincial knowledge in China. The results show that: R & D investment, R & D personnel, knowledge stock and foreign technology introduction have a positive contribution rate to the production of new knowledge, the contribution of each factor is different, and the average contribution rate of knowledge stock is the largest (0.460). The production of new provincial knowledge in our country has the spillover effect. The average growth of new knowledge in surrounding areas will increase by 1% on average, and the production of new knowledge in the region will increase by 0.469% on average.
