新长三角城市群创新空间格局演化与机理

The Evolution of Innovation Space and Its Mechanism in Yangtze River Delta Urban Agglomeration

以新长三角城市群26个城市为地理观测单元,以专利授权量为衡量指标,运用ESDA和GWR等方法,刻画2005—2014年城市群创新产出时空分异特征、影响因素及作用机理。研究发现:市域间创新产出绝对差异波动上升,相对差异波动缩小;创新产出水平相似的市域集聚分布,且集聚程度波动增强,而两极分化现象呈减缓态势;苏锡常都市圈与环杭州湾地区的崛起造成长三角创新活动的核心区域逐步突显;市域创新产出表现出收敛趋同的迹象;创新产出高增长型市域沿沪汉蓉、沪杭甬通道呈"Z"字型分布;各因子对创新产出的影响存在空间异质性,其中政府支持和产业集群环境是影响长三角城市群创新产出水平的主要驱动因素。

Taking 26 cities as the geographical observational units, patent granted as the measure index, this paper describes the space-time differentiation features, influencing factors and mechanism of innovation output in Yangtze River Delta Urban Agglomeration from 2005 to 2014 by using ESDA and GWR analysis methods. The results are as follows:(1)The absolute difference of innovation output of urban region is broadly increasing, and the relative difference is approximately narrowing.(2)Urban region of similar innovation output level distributes with agglomeration, and the degree of agglomeration is roughly expanding, while the two-stage differentiation trend is slowing down.(3)The rise of Suzhou-Wuxi-Changzhou metropolitan area and cities around Hangzhou Bay leads to gradually highlight the core area of innovative activities in the Yangtze River Delta.(4)The innovation output of the city domain shows signs of convergence.(5)The city domain of innovative output's high growth presents'Z'font distribution along the Shanghai-Han-Rong highspeed rail and Shanghai-Hangzhou-Ningbo channel.(6)The impact of each factor on innovation output is spatial heterogeneous. In addition, government support and industrial cluster environment are the main driving factors influencing the innovation output level of Yangtze River Delta Urban Agglomeration.
