摘　　要：以2009〜2016年沪深A股上市公司为样本,实证检验了我国上市公司创新活动(研发投入和专利产出)是否存在社会网络同群效应,并考察了企业社会网络特征对同群效应强度的影响。研究发现:同群企业创新能够显著正向影响企业创新,企业创新活动存在社会网络同群效应;在排除地区行业同群效应的干扰后,企业创新活动的社会网络同群效应依旧显著存在;制度环境对企业创新活动的社会网络同群效应具有负向调节作用,在制度环境欠佳的地区,企业创新活动表现出更强烈的社会网络同群效应;企业所处的社会网络位置越核心、中心度越高、联结数量越多、网络影响力越大,研发投入和专利产出的社会网络同群差异越小,企业创新活动的同群效应越强。Based on a sample of listed companies in China during the period 2009 to 2016,this study empirically tests whether corporate innovation activities(both R&D investment and patent output)have social network peer effect,and examines the impact of corporate social network characteristic on peer effect intensity.The results show that corporate innovation is positively affected by the peer firms'innovation in the social network,and corporate innovation has social network peer effect.After excluding the peer effect in the same region and industry,social network peer effect of corporate innovation still exists significantly.The institutional environment has a negative moderating effect on the social network peer effect of corporate innovation.Corporate innovation activ让ies have a stronger social network peer effect in areas with poor institutional environment.The corporate network centrality is negatively related to the peer difference of R&D investment and patent output,and positively related to the peer effect intensity of corporate innovation.
