城市内生竞争力与外生竞争力耦合协调研究——以成渝城市群为例

本文采用2006—2017年城市属性数据和2011—2017年信息流数据，测度成渝城市群城市内生、外生竞争力的耦合协调类型及其演化路径，对推进新型城镇化具有重要意义。结果表明：①城市内生竞争力呈波动上升趋势，由以成都为核心的单核心结构向“成都—重庆”双核心结构演变。②城市中心度升高，信息联系强度大幅度提升，城市外生竞争力显著增强。③城市内生、外生竞争力耦合协调度提升，耦合协调演化路径由轻度失调集聚型向低水平协调同步型、集聚型演化为主。

COUPLING COORDINATION STUDY BETWEEN ENDOGENOUS AND EXOGENOUS COMPETITIVENESS OF CHENGDU-CHONGQING URBAN AGGLOMERATION

City is a complex and open system, which competitiveness derives from the combined effect between its development and external relations. It is a great significance to measure the coupling coordination relationship between endogenous and exogenous competitiveness, and analyze its evolution path during urbanization for new-type urbanization. Based on urban attribute data in 2006-2017 and information flow data in 2011-2017 to measures endogenous and exogenous competitiveness and analyze the coupling coordination type and evolution path that using coupling coordination model. The results show that:1) Endogenous competitiveness is on the rise with significant regional differences, the spatial pattern evolved from single core with Chengdu to double core of Chengdu and Chongqing; The comprehensive competitiveness of cities, the competitiveness of science or technology and the competitiveness of opening to the outside world have been significantly improved. 2) As the degree of urban center increases, the intensity of information connection between cities has been greatly enhanced, forming a radial network structure with Chengdu as the core and Chongqing as the secondary core, it presents the exogenous competitiveness of cities has been significantly enhanced. 3) The degree of coupling coordination increases between endogenous and exogenous competitiveness, but the overall level is relatively low.
