Under the background of carbon neutrality, green development is the theme of today's times. The construction industry is an important part of the green development plan, and it is of great significance to study its green financing efficiency. Based on this, this paper uses the four-stage DEA model to explore the green financing efficiency of listed construction companies from 2019 to 2020. The conclusion shows that: firstly, the green financing efficiency of listed construction companies is low, and the demand for green financing has not been met. It is necessary to strengthen the support of green finance to meet the needs of its expansion. Secondly, the efficiency of green financing is significantly and complexly affected by external influencing factors. It is necessary to dialectically treat external influencing factors such as local industry development support, financial development level, and the number of patent authorizations. Thirdly, among the internal influencing factors, the proportion of independent directors has a significant positive impact on the green financing efficiency of listed construction companies, and the proportion of R&D investment has a significant negative impact. Listed construction companies need to increase the proportion of independent directors and control the proportion of R&D investment.
在碳中和背景下，绿色发展是当今时代的主题。建筑业是绿色发展计划的重要组成部分，研究其绿色融资效率具有重要意义。基于此，本文采用四阶段 DEA 模型，从 2019 年到 2020 年，探讨了上市建筑公司的绿色融资效率。结论表明：首先，上市建筑公司的绿色融资效率较低，绿色融资需求未得到满足，有必要加强绿色金融支持，以满足其扩张需求。其次，绿色融资效率受到外部影响因素的显著复杂影响，有必要辩证对待地方产业发展支持、金融发展水平和专利授权数量等外部影响因素。第三，在内部影响因素中，独立董事比例对上市建筑公司的绿色融资效率有显著的正向影响，研发投入比例有显著的负向影响。上市建筑公司需要增加独立董事的比例，并控制研发投入的比例。
