    Abstract: Baldwin 與 Robert-Nicoud (2006) 延伸Melitz (2003) 的架構以考慮貿易對短期與 長期產業生產力的影響。他們指出貿易可以增加短期的生產力但卻會犧牲生產力的長期 成長率。本計畫指出其原因為Melitz (2003) 的架構依賴固定的貿易成本以產生短期生產 力的成長。本計畫提出一貿易模型，考量競爭程度的增加為造成短期生產力成長的原 因，如此我們不需依賴固定成本。在這個架構下，貿易不但可以增加短期的生產力亦可 增加其長期的成長率。此架構亦可以與傳統的H-O 模型結合，故可以討論在有比較利益 下貿易對不同產業生產力的長短期影響。
    Baldwin and Robert-Nicoud (2006) extend Melitz (2003) and show that at steady state there is a trade-off between short-run productivity improvement and a lower long-run productivity growth. I argue that this is because in Melitz (2003), a significant fixed trading cost is needed to generate the result that trade forces low-productivity agents exit. I propose a methodology to show that increase of competition because of trade will generate similar results. Because of no fixed trading cost, there is no such trade-off at steady state. Trade not only improve productivity in the short-run but also increase growth rate in the long-run. Because the methodology I propose suitably fit the standard H-O framework, the model can be used to discuss the impact of trade on productivity and its growth rate when countries are different in factor endowment.
