【摘要】：选取长三角地区各城市2001-2012年专利申请受理量作为表征各城市创新水平指标,采用变异系数、基尼系数、赫芬达尔指数和空间自相关指标和方法,考察长三角地区创新空间格局演变特征,并使用空间回归分析方法,探讨长三角地区创新空间差异的影响因素。研究表明:(1)长三角地区整体创新空间差异和创新集中度呈下降趋势,近年来已趋向稳定。(2)长三角地区创新空间格局仍处在动态变化之中,但已基本形成以上海、南京为端点的创新高值集聚带。长三角地区创新空间已表现出正的空间相关性,但呈现出波动变化特征,空间相关性并不显著,仍存在一定程度的空间异质性。(3)城市创新已表现出一定程度的空间溢出效应。创新综合投入、创新环境和创新规模是长三角地区创新空间差异的主要影响因素。
[Abstract]:This paper selects the patent application acceptance of cities in the Yangtze River Delta region from 2001 to 2012 as the indicator of innovation level of each city, and adopts the coefficient of variation, Gini coefficient, Hefendal index and spatial autocorrelation index and method.This paper investigates the evolution characteristics of innovation spatial pattern in Yangtze River Delta region, and discusses the influencing factors of innovation spatial difference in Yangtze River Delta region by using spatial regression analysis method.The research shows that the spatial difference of innovation and the degree of concentration of innovation in the Yangtze River Delta region as a whole are decreasing, and in recent years, the spatial pattern of innovation in the Yangtze River Delta region is still in dynamic change, but it has basically formed in Shanghai.Nanjing for the end of the record high concentration zone.The innovation space of the Yangtze River Delta has shown positive spatial correlation, but it shows fluctuating characteristics, the spatial correlation is not significant, there is still a certain degree of spatial heterogeneity.) the urban innovation has shown a certain degree of spatial spillover effect.Innovation comprehensive input, innovation environment and innovation scale are the main influencing factors of innovation space difference in Yangtze River Delta region.
