摘　　要：本文在Dixit-Stiglitz模型中引入个体技能异质性,构建了一个异质个体贸易一般均衡模型,考察贸易自由化的福利影响。本文给出了贸易自由化一个新的福利来源,即贸易自由化将导致个体选择当企业家的临界技能水平上升,从而促使企业生产率、劳动力市场平均技能水平和技能种类上升,进而导致劳动力配置效率上升和总产出增加,最终使个体福利上升。This paper proposes a trade general equilibrium model with individual heterogeneity based on the Dixit-Stiglitz model in order to analyse the effect of trade liberalisation on national welfare.It proposes a new source of trade liberalization on welfare that the selection effect from trade liberalisation leads to an increase in the limiting of skill levels above which an individual decides to be an entrepreneur and below which he or she becomes a simple worker,which leads to an increase in business productivity,the average level of job qualifications and the variety of competencies existing in the labour market.This,on the other hand,promotes greater efficiency in labour allocation and an increase in total output,ultimately leading to an increase in individual well-being.
