4月18日,【明理讲堂2023年第18期】有幸邀请到新加坡国立大学商学院Lucy Gongtao Chen副教授为大家带来题为“讨价还价下竞争供应链的战略库存研究”的学术报告邀请。
Lucy Chen老师首先介绍战略库存是指企业纯粹出于战略考虑而非经营原因(如规模经济)持有的库存,并依次提出供应链上下游企业间的讨价还价现状。接着,Lucy Chen老师分别探究了在两个竞争性供应链系统中存在完全讨价还价和部分讨价还价下战略库存对供应链成员利润的作用,并且不同讨价还价情况下零售商是否使用战略库存是不一致的。Lucy Chen老师针对不同讨价还价情况下战略库存和批发价的均衡结果分析,并对照无讨价还价下传统竞争性供应链的战略库存结果开展了进一步的讨论分析。具体地,在完全讨价还价情况下,供应链间的横向竞争会导致战略库存持有策略不对称的均衡结果,即只有一条供应链主动持有战略库存,并在持有成本较低时从中受益,这反而会使得整个供应链系统的利润更糟。在部分讨价还价下,无论是否存在横向竞争,供应链中的零售商总是在讨价还价能力小、库存持有成本低的情况下持有战略库存。此外,在横向竞争中,当库存持有成本很小(高于阈值且不太大)时,战略库存会损害(提高)整体系统利润。同时,当存在横向竞争时,完全讨价还价可能不如部分讨价还价。
Lucy Gongtao Chen老师的精彩报告吸引了来自国内外高校的老师和学生,报告中,Lucy Chen老师处处体现出其严谨的学风以及渊博的理论学识,受到了参与人员的极高评价。
