摘　　要：产品价格波动和黏性反映市场的供需关系和配置效率,空间异质性以及城市间的经济关联进一步影响价格信号传递。本文基于市场关联视角,在结构引力模型估计中引入市场双侧供需关联,分析影响价格黏性的渠道:行业垄断、市场竞争和政府干预。本文以2020年疫情冲击作为准自然实验,验证市场间经济关联对航空公司定价决策的影响。研究发现:降低行业垄断和市场进入成本能够有效促进国内市场价格有效性。市场经济关联对价格黏性的影响随不同渠道存在显著差异。行业垄断导致航班价格动态调整能力下降,价格敏感性降低;市场竞争对价格黏性有抑制作用,竞争加剧造成航班价格调整频率增加;政府干预导致价格黏性下降。The volatility and stickiness of commodity prices reflect the supply-demand relationship and the allocation efficiency of the market.Spatial heterogeneity and the market relation between cities generate even more diversified price dynamics.We introduce the relationship between supply and demand in the structural gravity model estimation and analyze the influence channels of price stickiness:industry monopoly,market competition and administrative intervention.Using the 2020 epidemic shock in China as a quasi-natural experiment,we verify the impact of market relation on airline pricing dynamics.We find that reducing the industry monopoly and market entry cost can significantly result in effective price behavior.Market relation affects price stickiness through three channels:Industry monopoly leads to decreased capacity for price adjustment and reduced price sensitivity;market competition inhibits price stickiness,and the frequency of price adjustment increases as competition intensifies;administrative intervention effectively attenuates price stickiness.
