创新扩散与城市规模的关系研究——以中国副省级以上城市为例

阐述创新扩散理论及创新扩散与城市体系关系的相关文献,选取我国35个副省级以上城市,利用城市间创新扩散强度模型,实证分析城市规模和创新的关系及城市间扩散模式。得到结论:北京、上海扩散强度最大,东部城市普遍较高,扩散强度基本与城市人口规模成正相关关系。提出充分运用等级扩散规律,促进区域协调发展,积极开拓和改进交流渠道,继续扩大已有城市规模对创新扩散和经济发展、提升城市竞争力具有重要意义。

Through elaborating the literature of the theory of innovation diffusion and the relationship of innovation and urban system,seleet our country 35 sub-provineial cities,to use the cities innovation diffusion intensity model and demonstrate the relationship between city scale and innovation.We get the conclusion that Beijing and Shanghai have the biggest diffusion strengh,eastern cities are general high,they have positive comelation.And it put proposes that making use of hierarchical diffu-sion,promoting coorchinated regional develepment,continue to expand the existing urban scale for diffusion of innovation and e-conomic development.
