根据领英数据，多大比例的领英会员会对业务决策产生影响？

According to LinkedIn's internal data and research, four out of five (80%) of its members influence business decisions. This high percentage highlights LinkedIn's effectiveness as a platform for B2B marketing and sales, as it directly connects marketers with key decision-makers and influencers within organizations. The other options are incorrect because they do not reflect LinkedIn's published statistics on member influence.
