中國經濟通縮隱患成真?

去年2月,筆者在本專欄撰文,剖析新冠肺炎疫情之後出現的東滯西脹現象。一年半之後的今天,西脹回落,東滯猶在。本月9日,中國經濟運行的統計數據公布,7月份消費價格指數比去年同期下降0.3%,出現了自2021年2月以來的首次按年負增長;不僅如此,生產價格指數的按年跌幅為4.4%,延續6月的下降趨勢。

高才通未必通高才 香港幫方能幫香港

香港正鬧人才荒已經是不爭的事實。根據大型求職網站JobsDB最新發布的《2023年招聘、薪酬及福利調查報告》,有68%受訪企業表示招聘困難,而60%僱主指出填補職位不易,因為「難以招聘合適人才」。特區政府也不再猶抱琵琶半遮面,坦言人才缺口不容忽視。

香港創意 繁花似錦還是綠肥紅瘦?

筆者兩個月前在本欄撰文〈香江失健筆,本港缺奇才〉,論及香港文藝界花果飄零,創意行業難以振興。一些朋友頗有微詞,責怪筆者沒由來的悲觀。過去兩月,各種藝術節、文化節、展覽會、音樂會接踵而至,乃至五一黃金周前的美食市集、全港戲院日,無不四處人頭湧動,足見本地文藝文化產業活力十足。筆者自問:錯否,錯否?繁花似錦,卻道綠肥紅瘦!

香江失健筆 本港缺奇才

上周末,幾位朋友談起文壇現狀,大嘆香港連失健筆,人才凋零。去年年中倪匡仙逝,年底走了西西,今年年初劉紹銘過身;加上老病的、封筆的、歸隱的、出走的,昔日風流,盡被雨打風吹去。

競爭、合約與創造力:以平台市場上的小說寫作為例

在現今社會,愈來愈多的人以獨立生產者的身份參與經濟活動,零工經濟的規模和社會影響逐漸擴大。我們研究在中文小說寫作平台上,產品競爭如何影響零工工作者的努力和創意。小說作者與寫作平台按營利共享或按字計酬的合約方式,逐個篇章創作及售賣他們的作品。我們的研究利用政府對平台管理的一項新規則,來檢驗市場競爭對不同合約方式下作者行為的影響。具體而言,政府強制關閉一批專門從事愛情小說創作的不規範平台,導致創造愛情小說的作者轉移到管理規範的綜合性創作平台,從而加劇了綜合性平台上愛情類小說之間的產品競爭。其它類型的小說(例如科幻小說)不受此影響,可以作為有效的控制群來幫助因果推斷。我們發現,競爭加劇會令作者加快創作內容的速度,但對小說內容的新穎性影響微弱。然而,與按字計酬方式創作的小說相比,以營利共享方式創作的小說在競爭激烈的情況下,則不僅速度更快,而且內容更為新穎。此外,對處於產品生命週期初期的書籍,競爭對小說內容的新穎性影響更為顯著。最後,寫作平台在推廣合約書籍的努力,在競爭加劇之後,則大幅傾向於以按字計酬方式創作的書籍,從而大大提高這類書籍的點擊和訂閱率。此項研究有助於探討市場結構對零工經濟的影響,也對平台經濟反壟斷政策的製定有借鑒意義。
