【摘要】：利用区位基尼系数、空间自相关、相对发展率指数(NICH指数)以及空间面板数据模型等分析方法,以长江经济带沿线38个中心城市作为空间观测单元,结合专利授权量等相关数据,研究了创新产出的时空演化特征及其成因。结果表明:2000~2013年长江经济带沿线中心城市的创新产出在整体上逐年增长,地理集中度呈现波动下降趋势;长三角地区相对发展速度较快;创新产出的空间集聚程度表现出反"Z"字形的波动上升态势;创新产出的热点区域由长三角-成渝"双核心"空间结构发展成长三角"单极突出"空间格局,且长三角热点区域范围有所增长,冷点区域则分布在长江中游地带;技术溢出、政府行为、空间区位和金融支持均对长江经济带沿线中心城市的创新产出具有显著地正向影响,经济基础对下游城市具有促进作用。根据研究结论还提出了相应政策建议。
[Abstract]:Using the Gini coefficient, the spatial autocorrelation, the relative development rate index and the spatial panel data model, 38 central cities along the Yangtze River economic belt are taken as the spatial observation units. The temporal and spatial evolution characteristics and causes of innovation output are studied based on patent licensing and other relevant data. The results show that the innovation output of the central cities along the Yangtze River Economic Belt from 2000 to 2013 is increasing year by year, the geographical concentration is fluctuating and decreasing, and the relative development speed of the Yangtze River Delta region is relatively fast. The degree of spatial agglomeration of innovation output shows a trend of anti-Z fluctuation, and the hot spot of innovation output develops from the "double core" spatial structure of Yangtze River Delta and Chengdu-Chongqing to the spatial pattern of "unipolar prominence" in the Yangtze River Delta. Moreover, the hot spot area of Yangtze River Delta has increased, while the cold spot area has been distributed in the middle reaches of the Yangtze River. Technology spillover, government behavior, spatial location and financial support all have significant positive effects on the innovation output of the central cities along the Yangtze River Economic Belt. The economic foundation has the promotion function to the downstream city. According to the conclusions of the study, the corresponding policy recommendations are also put forward.
