本文利用文本情感分析，探討平台經濟的成長過程。平台經濟是一種新型態
的商業模式，平台的提供者並不生產產品，只提供實體或虛擬的平台服務，讓生
產者與消費者可以進行交易，並收取適當的費用作為營收。這種新興的商業模式
是如何成長，在過去的文獻較少探討，本研究利用自然語言處理的分析工具：文
本情感分析，來探討並比較兩家美食外送平台的成長過程：Foodpanda 與Uber
Eats。我們蒐集Google Play 的線上用戶評論作為原始資料，時間從2016 年10 月至2019 年11 月。根據文本情感分析視覺化的結果，我們發現Foodpanda 與Uber Eats 於2018 年7 月，在平台成長初期的情感分數皆為負值，顯示台灣社會大眾對於美食外送平台起初是有些抗拒的，但隨著平台的成長，兩者的情感分數都有逐漸提升的趨勢，又以Foodpanda 的情感分數上升的更為快速，甚至於2019 年7 月超越了Uber Eats，並且在這之後兩間平台的情感分數開始走向趨緩。本文接著進行比較個案分析，探討「如何」以及「為何」這兩家美食外送平台的情感分數是如此變化。本研究對於平台經濟的發展有所貢獻，更重要的是，我們以情感這一個獨特的視角來進行實證分析。

This article uses sentiment analysis to study the growth of platform economy. The platform economy is a new business model. The provider of platform does not produce products, but only provides physical or virtual platform services, so that producers and consumers can conduct transactions and charge appropriate fees as revenue. How this emerging business model has grown is rarely discussed in the past literature. This study uses the approach of natural language processing: sentiment analysis to explore and compare the growth of two food delivery platforms: Foodpanda and Uber Eats. We collected online user reviews from Google Play as empirical data in 2016-2019.
According to the results of visualization of sentiment analysis, we found that Foodpanda and Uber Eats had negative sentiment scores in the early stage of the platform growth in July 2018, showing that the Taiwanese market was somewhat resistant to the food delivery platform at first. But, with the growth of the platform, the sentiment scores of both have gradually increased, and Foodpanda's sentiment scores have risen more rapidly, surpassing Uber Eats in July 2019. Afterwards, the sentiment scores of the two platforms began to slow down. This article then conducts a comparative case analysis to explore how and why the sentiment scores changed so
much. This paper contributes to the development of platform economy, and more importantly, we conduct empirical analysis from a unique perspective of sentiment.
