    Abstract: 串流音樂平台的興起造成音樂產業從實體銷售漸漸轉向串流媒體與數位銷售,而此音樂產業改變可能影響歌曲結構的變化。本文分析串流媒體平台Spotify歌曲排行資料,與266名歌手的個別資料,旨在探討串流音樂平台的訂閱人數增加是否會造成歌曲長度縮短,並對歌曲長度縮短的機制提出推測以及實證。本文首要以固定效果估計法(Fixed-effect estimation)分析串流音樂平台的使用人數佔比與歌曲長度的關係,並以新冠疫情的政策與嚴重程度作為工具變數(Instrumental variables, IV),以兩階段最小平方法(Two Stage Least Square , 2SLS)去除內生性的影響。個體資料部分將利用固定效果估計法去分析歌曲長度與串流次數的關係,並分析歌曲長度變短的原因。實證結果發現串流音樂平台使用人數佔國家比例對於歌曲長度有顯著影響,使用人數比例每增加1%,歌曲長度將下降1.68%,推論平台使用人數增加將導致歌曲長度變短。另外,本文透過創作者在疫情前有無創建TikTok帳號探討歌曲長度縮短的原因,並以實證結果推論歌曲長度改變的因素不全然是因為消費者偏好篩選的結果。
    The rise of streaming music platforms has caused the music industry to gradually shift from physical sales to streaming media. This transformation in the music industry may affect changes in song structures. This article analyzes the song ranking data on the music streaming platform Spotify, as well as individual data from 266 artists, with the aim of exploring whether the increase in subscribers to streaming platforms leads to a decrease in song length. Additionally, the article proposes speculation and empirical evidence regarding the mechanisms behind the reduction in song length. The primary analysis in this article utilizes a Fixed-effect estimation to examine the relationship between the proportion of users on streaming music platforms and song length. The policy measures and severity of the COVID-19 pandemic are used as instrumental variables (IV) to control for endogeneity through a two-stage least square (2SLS) approach. In the individual-level analysis, a Fixed-effect estimation is employed to analyze the relationship between song length and the number of streaming instances, as well as to identify the reasons behind the decrease in song length. The empirical results reveal a significant impact of the proportion of users on streaming music platforms on song length. For every 1% increase in the proportion of users, song length decreases by 1.68%. It can be inferred that an increase in platform users leads to a reduction in song length. Furthermore, this article explores the reasons behind the decrease in song length by examining whether the creators had TikTok accounts prior to the pandemic. The empirical results suggest that factors influencing changes in song length are not solely a result of consumer preference filtering.
