皖江城市带创新能力差异研究

论文以2000-2012年皖江城市带每年的专利申请量作为区域的创新产出,运用Theil指数,对每个城市的创新能力进行测算并分析其差异。研究表明,以芜湖为核心的南部区域的创新能力稍弱于以合肥为核心的北部区域,这表现为2000-2012年间南部区域专利申请数的Theil指数均为负,而北部区域为正。但两个区域的Theil指数均向0靠近,而南部区域从负数逐渐变成0,这表明南部区域的创新能力发展更快。总体而言皖江城市带创新能力发展不均衡的局面仍将持续。

Research on the Difference of the Innovation Ability of Wanjiang City Belt

This paper regards patent applications data from 2000 to 2012 on Wanjiang City belt as the representation of the regional innovation output. Theil index is used to detect each city＇s innovation ability and analyze the difference of them. What the research shows is that the innovation ability of southern area with Wu Hu as the core is weaker than the north area with Hefei as the core. This can be known from the minus Theil index during 2000 to 2012 of patent applications in the southern area, whereas the plus index in the northern area. However, the Theil index of two areas is approaching to zero, and the Theil index of the southern area is from the negative into the zero, which indicates that the innovation ability in the southern area is developing faster. Overall, the unbalanced situation of Wanjiang City belt＇s innovation ability will continue.
