根据领英数据，每周发布 4 次动态的企业，内容参与度会提升 2 倍。

This statement is correct. LinkedIn's internal data consistently shows a positive correlation between posting frequency and engagement. Businesses that post at least four times per week often see a significant increase in content engagement, including likes, comments, and shares, compared to those with lower posting frequencies. This is because more frequent, valuable content keeps the audience engaged and increases the chances of their content being seen in the feed. The incorrect option is wrong because the data supports the claim.
