摘 要:技术创新是促使成渝地区双城经济圈成为增长极的核心动力。基于2014—2018年38个重庆市区县和15个四川省地级市的创新数据,利用熵权法确定成渝地区双城经济圈区域创新发展综合指数,利用区域创新TW值计算成渝地区双城经济圈区域创新极化值,并利用基于夜间灯光数据的修正创新引力模型计算成渝地区双城经济圈区域创新联系强度。结果表明:成渝地区双城经济圈的创新水平呈现明显的空间分异,表现为少数中心区县(市州)创新资源集中化,大部分中小区县(市州)创新水平较低;成渝地区双城经济圈区域创新极化指数TW值在2014—2018年呈现较弱的波动性;从成渝地区双城经济圈的区域创新联系强度来看,2015—2018年重庆市主城片区和四川省成都市较好地引领了区域内部创新发展,创新资源不能很好地在区域扩散。Technological innovation is the core driving force to make the Twin-City Economic Circle in Chengdu-Chongqing Area become the growth pole.Based on the innovation data of 38 districts and counties in Chongqing and 15 prefecture level cities in Sichuan Province from 2014 to 2018,the entropy weight method is used to determine the comprehensive index of regional innovation and development of the Twin-City Economic Circle in Chengdu-Chongqing Area,the TW value of regional innovation is used to calculate the regional innovation polarization value of the Twin-City Economic Circle in Chengdu-Chongqing Area,and the modified innovation gravity model based on night lighting data is used to calculate the regional innovation connection strength of the Twin-City Economic Circle in Chengdu-Chongqing Area.The results show that:the innovation level of t the Twin-City Economic Circle in Chengdu-Chongqing Area presents obvious spatial differentiation,which shows that a few central districts and counties(cities and prefectures)have centralized innovation resources,and most small and medium-sized districts and counties(cities and prefectures)have low innovation level;the TW value of the regional innovation polarization index of the two cities economic circle in Chengdu Chongqing region shows weak volatility from 2014 to 2018;From the perspective of regional innovation connection strength of the Twin-City Economic Circle in Chengdu-Chongqing Area,the main urban area of Chongqing and Chengdu City of Sichuan Province in 2015-2018 have better led the regional internal innovation development,and innovation resources cannot be well spread in the region.
