基于专利授权数的长江经济带创新差异的多尺度分析

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。

MULTISCALE ANALYSIS OF INNOVATION DIFFERENCE IN THE YANGTZE RIVER ECONOMIC BELT BASED ON THE NUMBER OF PATENTS

The implementation of the Yangtze River Economic Belt strategy has important significance for promoting the economic development of our country, and the Yangtze River Economic Belt innovation ability to promote the development is the key factor. Based on the quantitative research methods of standard deviation index, variation coefficient, location Gini coefficient and concentration index, the regional innovation differences of the Yangtze River Economic Belt in the urban agglomeration level, provincial and municipal level and its reasons were studied. The research showed that the regional innovation had a sustained growth trend, and the regional innovation difference increased with the increase of the regional scale. The main causes of different regional scales affecting the innovation of the Yangtze River economic belt were different. The social environment factor was the main factor that affected the innovation of urban agglomeration. The economic environment was the main factor affecting the innovation of the province. Urban innovation was the main external factors affecting the differences. Innovation concentration decreased with the increase of regional scale. The middle reaches of the Yangtze River and the Chengdu-Chongqing city groups were in the stage of innovation activities toward to the center of the city agglomeration. However, the Yangtze River Delta city group began to enter the diffusion stage of innovation activities, and the Yangtze River Delta city group would form a huge innovation cluster system.
