摘　　要：文章基于新新经济地理学的视角,在镇(乡、街道)一级的尺度上考察了"邻居"对出口企业生产率贡献的影响,分层线性模型(HLM)估计显示出口企业生产率进步的确存在邻居的知识溢出效应,即"邻居企业"生产率(Ntfp)每提升1%,相应地促进本镇出口企业生产率增长0.24个百分点。更深层次地从"邻居"的行业异质性、空间异质性和资历异质性三个层面,多维度检验了"邻居"知识溢出效应的价值。从镇级邻居的行业异质性看,同行邻居的专业化知识溢出相比广义(非同行)邻居的多样性知识更加显著,前者生产率提升更能够促进同镇出口企业的生产率增长;进一步发现"新邻居"的新知识溢出对出口企业的生产率贡献相对显著。Based on the New New Economic Geography Theory, this paper examines how neighbors influence export firm＇ s productivity at town （village, street） scale. Hierarchical Linear Model （HLM） estimation shows that there are neighbor effects in export firms＇ productivity progress, and the result remains ro- bust when we divide neighbors into ＂same industry neighbors different in- dustry neighbors leading neighbors＂ and ＂new neighbors＂. Furthermore, we find that the localization economy sourced from neighbors of the same indus- try （Intensive Neighbors） promotes export firm＇ s productivity more than the ur- banization economy does. Leading neighbor＇ s productivity significantly promotes export firm＇ s productivity. The quantity growth of new neighbors in the same in- dustry has a linear adverse effect on export firm＇ s productivity, while the rela- tionship between export firm＇ s productivity and the quantity of new neighbors in different industry is U type; When the level of new neighbor＇ s productivity is relatively high, it is helpful to increas the productivity level of old export firms.
