中国经济通缩隐患成真?

高才通未必通高才 香港帮方能帮香港

香港正闹人才荒已经是不争的事实。根据大型求职网站JobsDB最新发布的《2023年招聘、薪酬及福利调查报告》,有68%受访企业表示招聘困难,而60%雇主指出填补职位不易,因为「难以招聘合适人才」。特区政府也不再犹抱琵琶半遮面,坦言人才缺口不容忽视。

香港创意 繁花似锦还是绿肥红瘦?

笔者两个月前在本栏撰文〈香江失健笔,本港缺奇才〉,论及香港文艺界花果飘零,创意行业难以振兴。一些朋友颇有微词,责怪笔者没由来的悲观。过去两月,各种艺术节、文化节、展览会、音乐会接踵而至,乃至五一黄金周前的美食市集、全港戏院日,无不四处人头涌动,足见本地文艺文化产业活力十足。笔者自问:错否,错否?繁花似锦,却道绿肥红瘦!

香江失健笔 本港缺奇才

上周末,几位朋友谈起文坛现状,大叹香港连失健笔,人才凋零。去年年中倪匡仙逝,年底走了西西,今年年初刘绍铭过身;加上老病的、封笔的、归隐的、出走的,昔日风流,尽被雨打风吹去。

竞争、合约与创造力:以平台市场上的小说写作为例

在现今社会,愈来愈多的人以独立生产者的身份参与经济活动,零工经济的规模和社会影响逐渐扩大。我们研究在中文小说写作平台上,产品竞争如何影响零工工作者的努力和创意。小说作者与写作平台按营利共享或按字计酬的合约方式,逐个篇章创作及售卖他们的作品。我们的研究利用政府对平台管理的一项新规则,来检验市场竞争对不同合约方式下作者行为的影响。具体而言,政府强制关闭一批专门从事爱情小说创作的不规范平台,导致创造爱情小说的作者转移到管理规范的综合性创作平台,从而加剧了综合性平台上爱情类小说之间的产品竞争。其它类型的小说(例如科幻小说)不受此影响,可以作为有效的控制群来帮助因果推断。我们发现,竞争加剧会令作者加快创作内容的速度,但对小说内容的新颖性影响微弱。然而,与按字计酬方式创作的小说相比,以营利共享方式创作的小说在竞争激烈的情况下,则不仅速度更快,而且内容更为新颖。此外,对处于产品生命周期初期的书籍,竞争对小说内容的新颖性影响更为显著。最后,写作平台在推广合约书籍的努力,在竞争加剧之后,则大幅倾向于以按字计酬方式创作的书籍,从而大大提高这类书籍的点击和订阅率。此项研究有助于探讨市场结构对零工经济的影响,也对平台经济反垄断政策的制定有借鉴意义。
