实施长江经济带战略对推动我国经济发展具有重要的意义,而长江经济带创新能力的提升成为其发展的关键。基于标准差指数、变差系数、区位基尼系数和集中度指数的定量研究方法,研究长江经济带在城市群级、省级和市级多尺度上的区域创新差异及原因。研究表明:各尺度区域创新差异均呈现出持续增长趋势,并且区域创新差异随着区域尺度的增加而增加。影响长江经济带创新差异的各个区域尺度的主要原因各不相同,影响城市群创新差异的主要原因是社会环境因素,影响省域创新差异的主要原因是经济环境因素,影响城市创新差异的主要原因是对外开放因素。创新集聚随着区域尺度的增大而减小。长江中游和成渝城市群正处于创新活动向中心城市集聚阶段,而长江三角洲城市群进入创新活动的扩散阶段,并且长江三角洲城市群将形成巨大的创新集聚系统。
The implementation of the strategy of the Yangtze River Economic Belt is of great significance to the promotion of China’s economic development. The enhancement of the innovative ability of the Yangtze River economic belt has become the key to its development. Based on the standard deviation index, coefficient of variation, location Gini coefficient and concentration index quantitative research methods, the Yangtze River Economic Belt in urban clusters, provinces and municipalities on the multi-scale regional innovation differences and causes. The research shows that the innovation differences at all scales show a trend of continuous growth, and the differences in regional innovation increase with the increase of regional scales. The main reasons that affect the regional differences in innovation differences in the Yangtze River Economic Belt are different. The main reasons for the differences in innovation in urban agglomerations are social environmental factors and the main factors that affect the innovation differences in provincial regions are the economic and environmental factors and the main factors that affect the differences in urban innovation It is the factor of opening to the outside world. Innovative agglomeration diminishes as the size of the region increases. The urban agglomerations in the middle reaches of the Yangtze River and Chengdu-Chongqing are in the stage of agglomeration of innovation activities with the central cities while the urban agglomerations of the Yangtze River Delta enter the diffusion stage of innovation activities, and the urban agglomerations of the Yangtze River Delta will form a huge system of innovation agglomeration.
