摘　　要：将空间外部性与新新贸易理论相结合,推断出生产性服务业集聚对企业出口参与的动态影响,并运用Heckman两阶段模型对我国286个城市的制造业企业出口二元边际与生产性服务业集聚之间的关系进行了实证检验.研究发现,生产性服务业的专业化集聚和多样化集聚对制造业企业出口集约边际的影响均呈现显著倒U型特征;企业出口扩展边际与生产性服务业专业化和多样化集聚之间的关系则呈现显著的正U型特征.进一步的分样本检验结果显示,生产性服务业集聚对制造业企业出口二元边际的影响因企业所处城市规模、行业要素密集度以及所有制类型的不同而有所差异.此外,在作用机制方面,生产性服务业能够通过影响地区综合技术效率和社会创新体系促进制造业出口二元边际的扩张.The dynamic influence of the agglomeration of producer services on enterprise export partici-pation is deduced by combining the spatial externality and the new-new trade theory,and Heckman two steps model is employed to analyze the link between the dual margins of enterprises’export and the ag-glomeration of producer services in empirical tests.The results show that the impact of specialization and diversification agglomeration of producer services on the intensive margin of enterprises’export presents a significant inverted u-shaped feature,while the impact of the agglomeration of producer services on the extensive margin of enterprises’export is the opposite.Further,the impacts of the agglomeration of producer services on the dual margins of export are influenced by the following factors:city scale,indus-try factor intensity and ownership type.In terms of mechanism of action,producer services can promote the expansion of the dual margins of manufacturing export by its influence on the regional comprehensive technical efficiency and social innovation system.
