本研究以2007年至2012年台灣DRAM（動態隨機存取記憶體）產業中的廠商退出事件為研究背景，以2009年第一季奇夢達（Qimonda）破產為一劃分依據，分析後續廠商決策與台灣政策變化。使用資源配置模型探討三項議題，衡量奇夢達倒閉事件前後是否具有資源錯置的問題？政府是否可使用整併政策紓困DRAM產業困境？找出DRAM產業失敗的原因與時點以及未來發展策略。
因此，完成以奇夢達倒閉事件前後的資源配置效率分析，與二項反事實假設，假設事件後廠商整併與倒閉事件未發生的案例分析。得出結論為DRAM市場中廠商退出會使資源配置效率降低，且投入扭曲程度受資金來源穩定度影響。另外，可藉由整併兩家市場上扭曲程度較大的廠商提升資源配置效率，並改善資本閒置與怠惰勞工的問題。而奇夢達倒閉事件對於當時的DRAM產業有利，而政府並未適當介入重新分配資源才致使後續廠商轉型與下市。

This research starts by investigating the degree of input misallocation prevalent in the DRAM industry. Based on the severe input misallocation problems observed in the Taiwanese DRAM industry the article proceeds with the dynamic market structure adjustment to fix the computed input distortions. Splitting the timeline following the Qimonda insolvency, two scenarios featured by first the firm exit and team-up mergers of incumbent firms exhibit divergent changes of equilibrium misallocations. That is realized that exit event would push up efficient frontiers to drag down overall industry-wide misallocation while merger scenarios bring up significant improvement of input distortions featuring by higher production efficiency.
