【摘要】：现有城市地理研究主要基于重力模型、客货流网络和连锁模型等方法刻画城市网络。这些方法或是仅仅基于假设而可能与事实不符,或是数据难以获取,或是过于强调城市间的等级关系。通过引入合作专利数据,探索更加真实、平等的城市网络衡量方法。基于对长江经济带城市间创新联系的实证分析,发现目前城市间的创新联系以公司间(尤其是总部-分支机构间)合作为主;城市间创新联系存在非对称性和空间差异;实际创新联系与重力模型估算的创新联系存在正相关关系,但是相关系数不高;城市间创新联系的规模-位序符合Zipf定律,且存在两个无标度区;城市间创新联系受空间距离、行政级别、产业结构相似程度等影响,反映了距离衰减定律、行政区经济和产业链分工等规律对城市创新联系的解释力。
[Abstract]:The existing urban geography research is mainly based on gravity model, passenger and cargo flow network and chain model to depict urban network. These methods are either hypothetically based and may not be true, or data are difficult to obtain, or too much emphasis is placed on city-to-city hierarchies. Through the introduction of cooperative patent data, to explore more real, equal urban network measurement methods. Based on the empirical analysis of the innovation links among cities in the Yangtze Economic Belt, it is found that the innovation linkages among cities are mainly inter-firm (especially headquarters-branch) cooperation at present, and there are asymmetrical and spatial differences in innovation links between cities. There is a positive correlation between the actual innovation relation and the innovation relation estimated by gravity model, but the correlation coefficient is not high; the scale-position order of the innovation relation between cities conforms to Zipf's law, and there are two scale-free zones; The influence of administrative level and similar degree of industrial structure reflects the law of distance attenuation, the law of administrative region economy and the division of labor between industrial chain and other laws to explain the relation of urban innovation.
