Under the synergistic effects of accelerated global climate governance and deepening domestic green transition strategies, China's green bond market has demonstrated steady growth momentum guided by the "dual-carbon" goals. As pivotal policy milestones, the establishment of the carbon peaking and neutrality "3060" timeline in 2020, coupled with the updated Green Bond Endorsed Projects Catalogue (2021 Edition) released the following year, systematically established the green financial regulatory framework. This catalogue not only specifies funding scopes but also institutionalizes disclosure mechanisms and third-party certification requirements, laying policy foundations for market standardization and effectively promoting the normalization of green bond issuance. The new energy vehicle (NEV) industry, as a core sector for low-carbon transition and green development, faces emerging opportunities and challenges under dual drivers of policy support and technological innovation. The industry's capital-intensive nature combined with rapid market expansion creates compounded financing demands for enterprises. Green bonds have emerged as critical financing instruments for NEV manufacturers, offering advantages including cost efficiency, flexible terms, tax shield effects, and streamlined approval processes to alleviate funding constraints and advance green projects.
This study focuses on BYD's 2019 green bond issuance as an industry benchmark. By analyzing corporate financing structures, strategic planning, and capital allocation, it systematically examines core drivers behind green bond financing. Employing longitudinal/horizontal comparative analysis and event study methodology, the research evaluates financial metrics (financing costs and solvency ratios), environmental benefits (emission reduction outcomes), and market responses (stock price fluctuations and cumulative abnormal returns). Empirical findings reveal that the bond issuance not only alleviated financial pressures but also catalyzed supply chain decarbonization and received positive capital market feedback. The study identifies three primary motivations for BYD's green bond financing: addressing green project funding gaps, diversifying financing channels, and optimizing debt cost structures. While demonstrating multidimensional benefits across financial performance, market valuation, corporate reputation, and social impact, implementation challenges persist—particularly regarding insufficient cost advantages and environmental disclosure transparency. Recommendations emphasize enhancing information disclosure, implementing third-party certifications, and coordinated efforts among governments, enterprises, certification bodies, and investors.
This research fills an academic gap in NEV industry-specific green bond case studies, providing practical references for low-cost financing models and contributing to the maturation of China's green bond market. The findings offer operational insights for integrating green finance with industrial upgrading while supporting the sustainable development of eco-friendly transportation solutions.
