【摘要】：基于我国内地2001—2013年30个省市(除西藏外)RD人员全时当量、RD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。
[Abstract]:Based on the data of 30 provinces and cities in China from 2001 to 2013, including full-time equivalent R D funds, patent licensing volume, technical market turnover and new product sales income. By using principal component analysis method, the comprehensive evaluation index of innovation ability of provinces and cities was calculated, as well as the provinces (cities, autonomous regions, Beijing-Tianjin-Hebei region) along the line of "Belt and Road". On the basis of the innovation ability level of the three economic supporting zones of the Yangtze River economic belt, the Dagum Gini coefficient and the Kernel density estimation method are used. This paper makes an empirical study on the regional disparity and distribution of innovation ability in the three economic support belts. The results show that the innovation ability of the three economic support belts of the three major economic support belts is on the rise, and the province (city) along the line of "Belt and Road". The innovation ability of the economic belt is lower than the national average, while the innovation ability of the economic belt of Beijing-Tianjin-Hebei region and the economic belt of the Yangtze River is higher than the national average. (2) the overall gap of innovation ability in the three major economic support zones is constantly expanding, and after 2005, the regional gap has become the main reason for the continuous expansion of the overall gap; 3 Kernel density estimation shows that the innovation ability of the national and three economic support zones has been improved over time, but the regional gap has continued to expand.
