中国创新力的空间差异及其来源结构分解

Spatial Inequalities and Source Structure Decomposition of Innovation Capacity in China

基于一阶段泰尔(Theil)指数考察中国创新力的区域内和区域间差异,并在此基础上构造二阶段嵌套泰尔指数,进一步考察创新力的省内、省间和区域间差异。研究表明:中国创新力不断攀升,东部地区创新力最高。区位分布呈偏东北—偏西南的空间格局,分布重心逐年向南移动。创新力的总体空间差异先上升后下降:基于一阶段泰尔指数考察发现,区域内差异先上升后下降,区域间差异逐年扩大,区域内差异年均贡献率为79.8%;基于二阶段嵌套泰尔指数考察发现,省内差异先上升后下降,省间差异逐年下降,省内差异是空间差异最主要来源,年均贡献率为67.05%。“十四五”时期中国应更加注重创新力的均衡提升,全面塑造发展新优势。

This paper uses one-stage Theil index to measure the within region and between region inequalities of China's innovation capacity,and based on this,a two-stage nested Theil index is constructed to further examine the within province,between province and between region inequalities of China's innovation capacity.The results show:China's innovation capacity has been rising,and the eastern region has the highest innovation power.The spatial distribution pattern of innovation capacity is from northeast to southwest,and the distribution center moves to the south year by year.The overall spatial inequality of innovation capacity first rises and then declines:Based on the one-stage Theil index,it is found that the within region inequality first rises and then declines,and the between region inequality expands year by year.The average annual contribution rate of within inequality is 79.8%.Based on the two-stage nested Theil index,it is found that the within province inequality first rises and then declines,and the between province inequality decreases year by year,and the within province inequality is the main source of spatial inequality.The average annual contribution rate is 67.05%.During the"14th five year plan"period,China should pay more attention to the balanced promotion of innovation and comprehensively shape new advantages of development.
