【摘要】：文章研究以长江经济带109个城市为例,结合2004-2014年的专利授权量数据,利用变异系数、探索性空间数据分析方法以及面板门槛模型,探讨了创新活度的空间分异特征及其门槛效应,研究发现:长江经济带整体创新活度波动上升,地区间的差异平稳扩大且具有收敛趋势,区域间的创新活度趋于不均衡,长三角城市群的创新活度远远大于中三角和成渝两大城市群的创新活度之和;创新活度存在显著的空间分异格局,呈现"V"字空间形态,强势区域主要集中在上海及其外周城市;创新活度的空间指向性较为明显,其呈现"北高南低,东西两头高中间低"的空间趋势特征;创新活度存在显著空间组团分布的地理特征,其空间自相关程度的变化呈"N"字型态势,热点区和次热点区基本稳定集中在长江下游地区,具有扩散的趋势,次冷点区和冷点区分别集中在长江上游地区和中游地区;经济基础和市场导向对创新活度的影响均具有显著的三门槛效应,经济基础对创新活度具有"U"字型的正向作用,而市场导向对创新活度的负向门槛效应则呈现倒"U"字型。最后,文章提出了相关政策建议。
[Abstract]:This paper takes 109 cities in the Yangtze Economic Belt as an example, combining the patent licensing data from 2004 to 2014, using coefficient of variation, exploratory spatial data analysis method and panel threshold model. The spatial differentiation characteristics of innovation activity and its threshold effect are discussed. It is found that the fluctuation of overall innovation activity in the Yangtze economic belt is increasing, the differences between regions are steadily expanding and converging, and the innovation activity among regions tends to be unbalanced. The innovation activity of Yangtze River Delta urban agglomeration is far greater than that of the middle triangle and Chengdu-Chongqing urban agglomeration, and there is a remarkable spatial differentiation pattern of innovation activity, showing the spatial form of "V" character, and the strong regions are mainly concentrated in Shanghai and its surrounding cities. The spatial directivity of innovation activity is obvious, and it shows the spatial trend of "north high and south low, east and west high and middle low", and the innovation activity has the geographical characteristics of significant spatial group distribution. The change of spatial autocorrelation is "N". The hot spot and sub-hot spot are concentrated in the lower reaches of the Yangtze River, with the tendency of diffusion. The sub-cold point and the cold spot are concentrated in the upper reaches of the Yangtze River and the middle reaches of the Yangtze River, respectively. The influence of economic base and market orientation on innovation activity has significant three-threshold effect. The economic base has positive effect of "U" on innovation activity, while the negative threshold effect of market orientation on innovation activity is inverted "U" shape. Finally, the article puts forward the related policy recommendations.
