摘　　要：本文将空间外部性与新新贸易理论相结合,以推断城市蔓延对企业出口参与的动态影响,并运用Heckman两步法检验和分析了城市蔓延的外部效应对我国制造业企业出口二元边际的非线性影响。研究发现,城市蔓延所致市场拥挤的缓解和集聚经济的稀释等正负效应,对我国制造业企业出口集约边际的影响呈现显著的正U型特征,而对企业出口扩展边际的影响则呈现显著的倒U型特征。进一步将企业按照其所在城市蔓延水平、所处区域、所属行业的特征以及所有制类型划分的分样本检验结果显示,城市蔓延对具有不同特征的制造业企业出口二元边际的影响存在显著的差异。本文的研究结果为我们了解企业出口活动与当地城市结构之间的联系提供了一定的经验证据和政策启示。The theories of special externality and new-new trade are combined to deduce the dynamic impact of urban sprawl on firms export,and then,Hec km an two-step model is employed to investigate the nonlinear effect of urban sprawl on dual margins of the firms export.The research results show that the impact of urban sprawl on the intensive margin presents a significant U-shaped trend due to the fact that urban sprawl alleviates market congestion and decreases agglomeration economies.In the meantime,the impact of urban sprawl on extensive margin of firms export presents a significant inverted U-shaped trend.After dividing the samples according to the aspects which include the degree of urban sprawl,the region the firms are located in,the features of the industry,and the ownership of firms,the results indicate that there exists significant difference among the impacts of urban sprawl on different firms.Moreover,the results of the research provide us with empirical evidence and policy insight into the link between the firms export and urban sprawl.
