In fact , one serious side of the exhibition is that organisers also want to show that video gaming is an important industry, employing many skilled people.
这里的employing 如何剖析呢？逻辑主语是组织者吗？
Vedio gaming在此不是组织者的意思，而是电玩行业。这个行业雇佣不少技术人才。
employing...的逻辑主语为vedio gaming, 在句中作随着状语。比较：
Video gaming is an important industry, and it employs many skilled people.
这二个并列分句主语相同，谓语动词为相同时间，写成并列句则二个分句内容具备同样的重要程度。但也可突出其中任何一个分句，让其作主句，另一个分句降格为分词作状语，表示次要信息。比如：
Video gaming is an important industry, employing many skilled people. 突出前一个分句。
Being an important industry, vedio gaming employs many skilled people. 突出第二分句。
