：对学术机构进行客观公正的评价是科研管理过程中不可或缺的工作, 基于网络计量学的机构影响力评价成为学术机构评价研究中有别于传统文献计量方法的另外一种有效的评价手段。为了进一步探讨不同的分析策略对网络影响力的评价效果的影响，文章以我国342所大学作为研究样本，对比分析不同Web数据采集策略下，利用不同评价指标对机构的网络影响力进行评价的可靠性。研究结果表明，机构入链所属的大学域名的数量指标RD_EDU以及学院层面的链接指标Linknet与多个大学排名之间的平均相关系数接近0.8，并且高于以Webometrics Ranking of World Universities和uniRank为代表的网络影响力排名与ARWU、CARK和CUAA等大学排名之间的相关性强度。

It is an indispensable job to objectively evaluate academic institutions in daily scientific administration and webometrics-based evaluation technique has been increasingly becoming an effective way to fulfill this task besides traditional bibliometric indicators. In order to investigate the impact of different analytical strategies on the web influence of institutions, 342 universities in Mainland China were selected to compose the sample set to compare the reliability of different evaluating indicators on the web influence of institutions generated from different strategies of web data collection. Finally, the statistics shows that the numbers of educational domain names (RD_EDU) that linking to university websites, as well as the numbers of inlink on department level (Linknet) that university websites receive are significantly correlated (the average coefficient is nearly 0.8) with several transitional university ranking lists. Moreover, the correlation strengths are higher than that between prevailing web-based ranking lists (Webometrics Ranking of World Universities and uniRank) and traditional ones (ARWU, CARK and CUAA).
