数字平台通过降低消费者的搜索成本，有助于知名度不高的文化工作者找到知音，让在传统市场乏人问津的产品能以较低成本进入市场，令市场百花齐放。然而，在“流量为王”的时代，平台运营日趋偏颇，尤其是在中国的数字文艺娱乐市场，平台的推送和操纵能决定一部作品的命运，甚至窒碍产业创新。

This paper studies how social media affects the dynamics of protests and strikes in China during 2009–2017. Based on 13.2 billion microblog posts, we use tweets and retweets to measure social media communication across cities and exploit its rapid expansion for identification. We find that, despite strict government censorship, Chinese social media has a sizeable effect on the geographical spread of protests and strikes. Furthermore, social media communication considerably expands the scope of protests by spreading events across different causes (e.g., from anticorruption protests to environmental protests) and dramatically increases the probability of far‐reaching protest waves with simultaneous events occurring in many cities. These effects arise even though Chinese social media barely circulates content that explicitly helps organize protests.

当今经济结构变化极快，投资教育的开支不一定会带来高回报，那么上大学还值得吗？ 由于内地经济处于调整期，大学毕业生不单难找工作，更不寻常的现像是，学历愈高的毕业生反而愈难就业。笔者认为这种现象的主要原因是中国教育产业在过去20年扩张过度，加上经济发展不均加剧，社会流动性减弱，抑制了教育回报。而人工智能技术的广泛使用，为未来的教育回报带来更大的不确定性。

One of the indicators of whether a city can be considered as an international metropolis is perhaps the English proficiency of its residents. According to the EF English Proficiency Index report in 2023, Hong Kong ranked fourth among 23 countries and regions in Asia. However, there are two examples of different attitudes towards English in developed areas of Asia.
