摘要
区域一体化是促进经济高质量发展的有效途径,对提升经济韧性具有重要作用。研究从抵抗恢复力、适应调节力和创新转型力3个维度评价城市经济韧性;以长江经济带一体化战略实施为准自然实验,选取2008—2020年中国238个地级以上城市面板数据,运用合成控制法和双重差分模型实证研究了长江经济带一体化战略对城市经济韧性的影响效应和作用机制。研究表明:长江经济带一体化战略的实施提升了城市经济韧性,且该结论在一系列稳健性检验后仍然成立;长江经济带一体化战略对城市经济韧性的影响存在异质性,下游城市经济韧性的战略促进效应更为显著;机制分析表明,产业结构优化和科技创新能力是长江经济带一体化战略赋能城市经济韧性提升的重要机制。鉴于此,在建设全国统一大市场的背景下,长江经济带城市应充分发挥区域一体化优势,协同提升区域创新能力,促进区域协调发展,全面提升城市经济韧性,高水平实现长江经济带高质量发展的目标。
Regional integration is an effective way for high-quality economic development and matters in improving economic resilience.It evaluates urban economic resilience from three dimensions including recoverability,adaptability,and innovative transformation.In a quasi-natural experiment based on the implementation of the Yangtze River Economic Belt integration strategy,panel data of 238 cities at prefecture level or above in China from 2008 to 2020,and synthetic control method and double difference model are employed to empirically study the impact effect and mechanism of Yangtze River Economic Belt integration strategy on urban economic resilience.The results show that:(1)the implementation of the Yangtze River Economic Belt integration strategy has improved urban economic resilience,which still holds after a series of robustness tests;(2)such impact of the integration strategy on urban economic resilience is heterogeneous,and the strategic promotion effect on that of downstream cities is more significant;and(3)through mechanism analysis,industrial structure optimization and scientific and technological innovation capabilities are important mechanisms for the Yangtze River Economic Belt integration strategy to empower urban economic resilience.In view of this,in the context of building a unified national market,cities along the Yangtze River Economic Belt should give full play to the advantages of regional integration,coordinate to enhance regional innovation capabilities,promote coordinated regional development,and comprehensively enhance urban economic resilience for the purpose of high-quality development of the Yangtze River Economic Belt at a high level.
