摘要:

以浙江省为例,分析与探讨基于引力模型的区域创新产出空间联系。根据最大引力线数量与区域创新产出联系总量确定了区域创新产出空间联系的中心城市,并结合断裂点公式测度了中心城市的创新产出辐射范围。研究发现,与2005年相比,2011年各县、市区的区域创新产出联系量与区域创新产出联系总量有明显增加,但区域创新产出联系的空间格局并未有显著变化,联系密集区主要集中于杭州、宁波两地;二、三级节点城市发生明显变化,而杭州市辖区始终是浙江区域创新产出联系的中心城市;中心城市辐射区范围增大,除宁波市辖区外,中心城市对节点城市的辐射效果均略有增强。基于此,提出加大区域创新投入,优化创新环境,完善城市、县市间道路建设,加强信息发展,缩短区域之间的硬距离与软距离,增强区域创新产出的空间联系等政策建议。

Abstract:

Research on spatial linkage of regional innovation output and analysis of the radiation range in the central city have important practical significance to advance the spatial linkage of regional innovation output and promote the level of regional innovation output. This article analyzes the spatial linkage of regional innovation output based on gravity model, identifies the central city according to the number of the largest attraction linkages and total spatial linkages of regional innovation output and calculates the radiation range of the central city by breaking point formula in Zhejiang Province. Compared to the level in 2005 and 2011, the quantity of regional innovation output spatial linkage and total amount of linkages have increased obviously, but the spatial pattern of regional innovation output linkage has changed little with the concentrated areas mostly focused in Hangzhou and Ningbo. Although the cities with second and third level have had overt changes, Hangzhou City has always been the central city of spatial linkage of regional innovation output in Zhejiang. The radiation area in the central city has been expanded. The radiation effect of central city has strengthened slightly except Ningbo City. Based on this conclusion, this article puts forward some suggestions such as increasing the regional innovation input, optimizing the environment of regional innovation, improving and perfecting the construction of the highway and railway in cities, reducing the hard distance and soft distance between regions and promoting the spatial linkage of regional innovation output.

Key words: gravity model, regional innovation output, spatial linkage
