摘要
本文以成渝城市群内16个地级及以上城市的经济发展数据以及衡量创新能力的相关指标,构建城市群内部经济发展水平与创新能力水平两系统间的耦合协调模型,发现两系统间的耦合协调度在城市群内差距较大,且有较为明显的梯度,其创新能力的空间自相关系数表现为明显的高低集聚,且高低集聚情况在观测期内呈现先加剧后缩小的变化。运用空间面板回归分析,发现区域内创新对于城市经济增长有显著的促进作用,创新指标每上升一个单位将促进区域内城市经济增长0.0536个单位。鉴于此,应发挥成都、重庆作为区域创新中心、经济中心的辐射带动作用,推动区域内城市经济实力和创新实力提升。
Based on the economic development data of 16 cities at prefecture level and above in Chengdu Chongqing urban agglomeration and the relevant indicators to measure the innovation ability,the coupling coordination model between the two systems of the internal economic development level and innovation ability level of the urban agglomeration is constructed.It is found that the coupling coordination degree between the two systems has a large gap within the urban agglomeration,and there is a relatively obvious gradient,and the spatial autocorrelation coefficient of the innovation ability shows obvious high-low clustering,and the situation of high-low clustering increases first and then decreases in the observation period.Using spatial panel regression analysis,it is found that innovation in the region has a significant role in promoting urban economic growth,and each unit of innovation index rising will promote urban economic growth in the region by 0.0536 units.Furthermore,it is suggested that Chengdu and Chongqing should play a leading role as regional innovation centers and economic centers to promote the economic strength and innovation strength of cities in the region.
