| 摘 要： | 本研究通过引入点格局分析方法，以湖南省2013年专利数据为研究样本，基于细粒度的专利地址空间数据，分析了湖南省创新活动空间点格局及其影响因素。研究发现：湖南省创新活动呈现以长株潭地区为中心，向外逐渐递减的“核心-边缘”空间异质性结构，且创新活动空间集聚的最佳地理尺度在20km-21km之间。同时创新活动空间分布强度受到每平方公里GDP和最近道路距离两个因素的显著影响，且由于经济活跃度非连续性的存在造成了每平方公里GDP对创新活动的差异影响。文章认为鼓励创新发展的政策应充分考虑区域经济发展的不平衡性，在区域经济发展水平较高的地区，应该加大对自主创新的激励，而在经济不发达地区则强调道路通达性对加强创新溢出和创新融合的影响。

Research on heterogeneity point pattern of technological innovation and its influencing factors |

| Abstract: | In order to solve the modifiable areal unit problem in previous research, This study uses the point pattern analysis method with the fine-grained patent address space data of 2013 in Hunan Province, to analyzes the spatial pattern of innovation activities in Hunan Province and its influencing factors. The study finds that: There is heterogeneity in the spatial distribution of innovation activities in Hunan Province, showing a single-center “core-periphery” structure spreading out from Changsha, Zhuzhou and Xiangtan district and the best geographic scale for innovation spatial agglomeration is between 20km and 21km. After controlling the influence of innovation input factors, the GDP per square kilometer and the point distance from the road have significant impact on the intensity of innovation activity distribution. And because of the discontinuity of economic activity, the GDP per square kilometer has a differential impact on innovation activities. Lastly, we conclude that the policies to encourage the development of innovation should fully consider the imbalance of regional’s economic development. while incentives for independent innovation should be promoted in developed regions, road accessibility that increasing innovation spillovers in agglomeration should be emphasized in developing regions. |
