中国省际知识产权保护空间关联网络研究

运用主成分分析法测算2007-2017年中国省际知识产权保护强度，借助引力模型识别中国省际知识产权保护空间关联关系，在此基础上通过社会网络分析方法对中国省际知识产权保护空间关联网络进行深入分析。结果发现：首先，中国省际知识产权保护强度呈现显著的地区差异，且各省份间知识产权保护强度并非独立存在；其次，中国省际知识产权保护空间关联呈现出典型的网络结构形态，网络连通性较好且不存在明显等级性，但空间关联关系紧密程度有待加强；再次，不同省份由于经济发展水平和地理位置等不同在空间关联网络中表现迥异；最后，中国省际知识产权保护空间关联网络不可分割，不同板块在知识产权保护方面相互依赖，营造了一个信息互通的良好平台。

A Study of the Spatial Correlation Network Structure of Inter-Provincial Intellectual Property Rights Protection in China

In this paper, the principal component analysis method is used to calculate the intensity of inter-provincial intellectual property rights (IPR) protection in China from 2007 to 2017, and the spatial relationship of inter-provincial IPR protection in China is identified by the gravity model.On this basis, the social network analysis approach is employed to analyze the spatial correlation network structure of inter-provincial IPR protection in China.The results show that: Firstly, there exist significant regional differences in the intensity of IPR protection among provinces in China, and the intensity of IPR protection among provinces does not exist independently.Secondly, the spatial correlation of IPR protection among provinces in China presents a typical network structure.The network connectivity is good without obvious hierarchy, but the degree of spatial correlation needs to be strengthened.Thirdly, due to different levels of economic development and geographical location, different provinces have different performances in the spatial correlation network.Finally, the spatial correlation network of China's inter-provincial IPR protection is inseparable, and different sectors are interdependent.A good platform for information exchange is constructed by the spatial correlation network of Chinese IPR protection.
