长江经济带上游地区创新能力的空间差异研究

Study on Spatial Difference of Innovation in Upper Reaches of Yangtze River Economic Belt

选取长江经济带上游地区共4个省47个市州为研究地域,以各地区专利授权量为评价指标,对长江经济带上游地区创新能力的空间分布差异进行分析。研究结果表明:第一,从总体空间分布来看,长江经济带上游地区创新能力差异显著,呈现三个层级现象,即成都和重庆为第一层级,昆明、绵阳和贵阳为第二层级,其余地区为第三层级;第二,从空间聚类分布来看,长江经济带上游地区创新能力较强的地区主要分布在省会城市和科技城;第三,长江经济带上游地区各市州的经济发展状况、创新投入与产出以及创新主体等因素,对各地区创新能力的空间差异有显著影响。

In the upper reaches of the Yangtze river economic belt 4 provinces and 47 cities at prefecture level as the study area,based on the patent grant measure regional innovation ability,innovative ability of upper reaches of the Yangtze river economic belt in 2016 space differences were studied.The results show that:(1)From the perspective of the spatial distribution of overall,significant difference was found in upper reaches of the Yangtze river economic belt innovation ability,Chengdu and Chongqing as the first gradient,Kunming,Mianyang and Guiyang as the second gradient,the rest of the third level 3 gradient phenomena of the gradient.(2)From the perspective of spatial clustering distribution,the region with strong innovation capability in the upper reaches of the Yangtze river economic belt is mainly distributed in provincial cities and technology cities.(3)The economic development status,innovation input and output,and innovation subjects of various cities in the upper reaches of the Yangtze river economic belt have an important impact on the spatial distribution of innovation capacity.
