政府補助、換電站與綠色採購：臺灣電動機車需求的實證研究

Subsidy, Battery-Swapping Station, and Green Purchase: Evidence from Electric Motorcycles in Taiwan

本文旨在探討政府補助與換電站佈建對臺灣電動機車需求的影響，並探討臨近縣市的換電站設立是否存在網路效果，促進電動機車的需求。利用臺灣本島19個縣市2018年到2022年的半年期資料為研究樣本，實證結果發現：政府補助對電動機車的銷售量具正向顯著的影響，特別是汰舊換新補助。其次，換電站的技術基礎建設佈建亦促進電動機車的採用。然而，鄰近縣市換電站的網路效果相當有限，隱含電動機車的使用為縣市內的短途旅程為主。不同的頑強性檢定支持上述的實證結果。

This study investigates the influences of government subsidies and battery-swapping stations (BSSs) on the demand for battery electric motorcycles (BEMs) in Taiwan. In addition, we explore whether BSSs in neighboring regions, a network effect, influence BEM purchase. Based on a county-level panel dataset spanning from 2018 to 2022 in Taiwan, our empirical findings highlight the significant role of government subsidies, particularly the“out with the old and in with the new”subsidy, in facilitating BEM adoption. Furthermore, the presence of technological infrastructure, BSSs, positively influences BEM sales. However, our study does not find a robust network effect associated with BSSs in neighboring regions. A battery of robustness checks confirm the above findings.
