长江经济带城市协同发展水平测度

Measurement of coordinative development level of Changjiang Economic Zone

从收入协同和技术协同的角度分析了中国长江经济带城市协同发展的现状。结果显示:长江经济带城市存在显著的技术协同发展关系,收入上存在一定的区域性差异;分区域看,东部地区在收入协同和技术协同上均表现出很强的协同性,中部地区具有较强的技术协同而收入协同不足,西部地区虽然具有收入协同性和技术协同性,但其程度不如东部地区;分时间段看,在两个时间段内,技术都存在显著的协同性,且技术的协同性在2010-2016年时间段更高,而收入仅在2003-2009年时间段存在显著的协同性,这意味着经济动能在两个时间段发生了转换,技术创新协同对长江经济带经济增长的驱动效应不断增强。
