Green bonds have proven highly effective in meeting the strategic needs of corporate green transformation and reducing financing costs. Therefore, studying the motivations for issuing green bonds in the new energy vehicle (NEV) industry and their resulting effects carries practical significance. This paper focuses on BYD, the only private enterprise in the NEV sector that has issued green bonds, utilizing stock price data from January to May 2019 and applying event study methodology to examine the relationship between green bond issuance and stock price fluctuations. Empirical findings reveal: (1) Green bond issuance generates immediate short-term positive stock price effects, as companies aligning their development directions with national policies through green bonds gain investor support. To some extent, this research provides references for NEV enterprises exploring green financing models and contributes to advancing China's green bond market development.
