黄河流域科技创新的时空格局及其经济效应

Spatial and Temporal Pattern of Technological Innovation and Its Economic Effect in the Yellow River Basin

基于2005—2018年专利授权数据,构建科技创新评价指标,使用空间分析方法和空间计量模型探讨黄河流域科技创新时空格局及其经济效应。研究发现:(1)黄河流域科技创新规模、质量、活力和综合水平呈不断提升趋势,不同城市间科技创新水平差异较大,全局Moran’s I呈现先增大够降低的倒“U”型特征;(2)科技创新综合水平呈现东高西低的空间格局,创新水平较高的地区主要分布在省会城市及重点城市化地区,城市群地区创新的3个指标均明显高于黄河流域的平均水平,其中山东半岛城市群和中原城市群科技创新水平最高;(3)科技创新具有显著的经济促进效应,其中创新规模对黄河流域创新发展的促进作用最为显著,其次是创新活力和创新质量,创新的经济促进效应在非城市群地区不显著。研究结论为黄河流域高质量发展和科技创新政策制定提供参考。

Based on the patent grant data from 2005 to 2018, the evaluation index of regional innovation is constructed,and we explore the spatial and temporal pattern of technological innovation and its economic effects in the Yellow River Basin. The results show as follows :(1) The scale, quality, vitality and comprehensive level of technological innovation in the Yellow River Basin are constantly improving, and the level of technological innovation varies greatly among different cities;The Moran’ I index shows an "inverted U" pattern, which increases first and then decreases;(2) The comprehensive level of technological innovation presents the spatial pattern of high in the east and low in the west. The areas with higher innovation level are mainly distributed in provincial capital cities and key urbanization areas, and the three in dictators of innovation in urbanagglo me ration are as are significantly higher than the average level of the Yellow River Basin,of which the Shandong Peninsula Urban Agglomeration and the Central Plains Urban Agglomeration have the highest level of scientific and techno logical innovation;(3) Technological innovation has a significant economic promotion effect, and the innovation scale has the most significant promoting effect on the innovation development of the Yellow River Basin, followed by the innovation quality and innovation vitality;The economic promotion effect of innovation is not significant in non-urban agglomeration areas. The conclusions of this study can provide scientific reference for the high-quality development and scientific and technological innovation policy formulation of the Yellow River Basin.
