中文摘要：

鉴于企业研发组织内部沟通网络对研发组织中高效、低成本地实现技术信息共享的重要性，本文首先介绍了结构洞的测度方法，并对中间中心性方法进行改进；其次分析了某企业研发组织沟通网络的结构洞情况，指出非正式沟通网络和专业沟通网络的相关性；然后通过比较改进的中心度算法、传统的中心度算法与限制度指标的相似性，验证了该算法的有效性；最后提出一种削弱沟通网络中“核心人物”垄断地位的“搭桥”策略。结果发现：改进的中心度算法适用于带权值沟通网络结构洞的测定，验证了该算法加权方法的有效性，并给出通过非正式组织促进技术信息共享的对策。

英文摘要：

In view of the importance of realizing technological information sharing efficiently and cost effectively among enterprise R＆D organization internal communication network, this paper mainly is focused on the meas- urement of communication effect on enterprise R＆D organization internal communication network and its counter- measures for improving it. It first introduces the structure holes measuring algorithm, and improves the intermedi- ate centricity algorithm. Secondly it analyzes the structure holes among a R＆D organization communication net- work in a certain enterprise, and points out the correlation between informal communication network and profes- sional communication network. Then it confirms the effectiveness of this weighted algorithm by comparing the similarity of improved center algorithm, traditional center algorithm and the constrain index. At last, it puts for- ward a ＂bridging＂ strategy aimed at weakening the monopoly position of ＂core people＂ in communication net- works. The study finds that the structure holes measuring algorithm also applies to the measurement of structure holes among weighted communication network, confirms the effectiveness of this weighted algorithm, and then gives countermeasures for promoting technical information sharing among organizations by adjusting informal organizations.
