Abstract: The crucial factors of the impact of service industrial cluster on mansions’ productive efficiency are industries in clusters, headquarters and the diversity of industries of a mansion. We chooses traffic & business district in Dongchen district in Beijing as the case to research the relationship among cluster, industries’ diversity and productive efficiency through response and influence coefficient, linkage coefficient and data envelopment analysis. The conclusions find that the decrease of diversity of industries in a mansion can increase its productive efficiency. A mansion where headquarters are in has higher productive efficiency than others. Furthermore, if a mansion where headquarters are in has single or less diverse industries, its productive efficiency will higher than other mansions where headquarters are in. Therefore, high agglomeration of single industries is important for a mansion for increasing its productive efficiency.

摘要： 服务业集群对提升楼宇内行业生产效率的作用，受到行业集聚、总部企业入住与楼宇内行业多样性的影响。本文以北京市东二环交通商务区服务业和楼宇为研究对象，通过产业感应度与影响度分析、关联度R值计算以及数据包络分析法，探讨商务区服务业集群内各个楼宇的行业集聚多样性与其行业生产效率的关系。实证结果表明，楼宇内聚集的行业愈单一，愈能够发挥规模化的优势，提升自身的生产效率；而入住了总部企业的楼宇，总部企业规模愈大，楼宇的生产效率也将愈高。因此，服务业的空间布局应追求楼宇内单一行业的高度集聚，以提高生产效率。
