本文以金融危机前后曾出现的出口退税较大调整为背景，应用面板平滑转换模型（ PSTR）对出口行业“盯市”（依市定价）程度与出口退税、行业集中度之间的关系展开探讨。研究结果表明，就行业集中度而言，无论危机前还是危机后始终对出口行业的PTM行为产生影响，且均与PTM存在平滑转变的非线性关系；出口退税仅在危机后的大幅提升后才对PTM影响显著，并表现为突变的快速向下的门限效应，而危机前对PTM并无影响；与出口退税相比，行业集中度对PTM的影响虽非立竿见影但却是缓慢且持久的。%Using the more recently developed panel threshold regression models , this paper investigates the nonlinear re-lationship between Pricing to market ( PTM) of export prices on industry level and concentration ratio of industry and nonlinear relationship between Pricing to market ( PTM) of export prices on industry level and export tax rebates under two different eco -nomic backgrounds.The results of the study include the following four points.First, PTM before the financial crisis is differ-ent from PTM after the financial crisis.Secondly , in terms of industry concentration , industry concentration always exercises a great influence on PTM under different economic backgrounds , and there is a nonlinear relationship between PTM and industry concentration under different economic backgrounds.Thirdly, In terms of export tax rebates , there is neither linear nor nonlin-ear relationship between PTM and export tax rebates before financial crisis while export tax refund has significant effects on PTM after financial crisis.There is a threshold effect between PTM and export tax refund after financial crisis.Finally, Com-pared with the export tax rebate , industry concentration has more significant effect on PTM.
