摘　　要：利用248家国防科技相关企业与具有军工资质的民营企业2009-2017年面板数据,分2009-2012年、2013-2017年两阶段研究产品市场竞争、知识外溢与企业技术效率间的关系。结果发现,产品市场竞争对于企业技术效率提升具有显著促进作用;相较于国防科技相关企业,这种正向效应在具有军工资质的民企中表现得更为显著,并且随着国防与民营经济的融合发展,这两种正向效应更为显著。进一步引入知识外溢与产品市场竞争交互项发现,无论是技术人员知识外溢还是技术人员产出外溢,随着外溢程度增加,均会抑制产品市场竞争对企业技术效率的正向影响;在国有国防科技相关企业中,技术人员产出外溢效应的抑制作用更强。This paper using the panel data of 248 defense technology enterprises and private enterprises with military qualification integration listed companies from 2009 to 2017,studying the relationship between product market competition,knowledge spillover and enterprise technical efficiency in two stages(2009-2012,2013-2017).The results show that product market competition has a significant promoting effect on the improvement of technological efficiency of enterprises,and this positive effect in private enterprises with military qualification is more significant than in defense technology,and with the further integration of defense and private economy,these two positive effects will be more significant and stronger than before results show.The interactive term of knowledge spillover and product market competition is further introduced and the empirical results show that the spillover of technical personnel's knowledge and output will restrain the positive effect of product market competition on technical efficiency with the increase of spillover degree.And in defense technology enterprises,the output spillover effect of technicians has a stronger inhibiting effect.
