基于锡尔系数的广东省城市创新能力差异研究

Research on the Differences of Urban Innovation Capacity in Guangdong Province Based on the Theil Index

运用锡尔系数的方法,以专利授权数为变量,通过GDP和人口数2种不同的比重加权方法对比,对广东省各城市间的城市创新能力进行测算并分析其差异。研究表明:以GDP比重加权的城市创新能力差异呈减小趋势,而以人口数比重加权的创新能力差异呈增大趋势;城市越来越重视城市创新的建设,以创新带动城市发展;人口增长速度与城市创新能力有一定的关联,是造成城市创新能力差异的重要原因。

Taking the number of patents as variables and using the methods of the weighted with both GDP and population, the paper examines the differences of urban innovation capacity in Guangdong Province based on the Theil index. It shows that the urban innovation capacity differences are reduced by the weighted with GDP, and enlarged by the weighted with population ; cities are taking more and more attention to the construction of urban in- novation, by which they develop themselves; the population growth rate has certain relevance with the city innova- tion ability, which is the main reason of the urban innovation ability differences.
