摘要
基于我国内地2001—2013年30个省市(除西藏外)R&D人员全时当量、R&D经费、专利授权量、技术市场成交额、新产品销售收入5个指标数据,采用主成分分析法,计算得出各省市创新能力综合评价指数,以及全国和"一带一路"沿线省(市、自治区)、京津冀地区、长江经济带三大经济支撑带的创新能力水平。在此基础上,利用Dagum基尼系数和Kernel密度估计方法,对三大经济支撑带创新能力的地区差距及分布动态进行实证研究。结果发现:①三大经济支撑带创新能力呈不断上升趋势,"一带一路"沿线省(市、自治区)经济带的创新能力低于全国平均水平,而京津冀地区经济带和长江经济带的创新能力高于全国平均水平;②三大经济支撑带创新能力的总体差距不断扩大,2005年之后,地区差距成为造成总体差距不断扩大的主要原因;③Kernel密度估计显示,随时间推移,全国和三大经济支撑带的创新能力虽然得以提升,但地区差距仍呈现持续扩大趋势。
Based on provincial data of full-time equivalent of R＆D personnel,expenditure on R＆D,number of patent granted,technology market turnover and new product sales revenue from 2001 to 2013,this paper used principal component analysis method to calculate provincial comprehensive evaluation index of innovation capability,and calculated innovation capability of three major economic zone based on the comprehensive evaluation index,and then discussed regional disparity and distribution dynamics of three major economic zone with Dagum’s Gini coefficient and Kernel density estimation method.The study found that the level of innovation capability of three major economic zone is rising.The innovation capability of Beijing-Tianjin-Hebei and Yangtze River economic zone is higher than the national average level,and the innovation capability of Belt and Road along the province（city,autonomous region）is lower than national average.Gini coefficient and its decomposition result suggest that the regional disparity of innovation capability is increasing.After 2005,internal disparity of regions is the major source of overall inequality.Kernel density estimation indicates that although innovation capability of China and three economic zone is improving,regional disparity continues to expand.
