AI总结:

该研究以ESG与财务绩效关系的系统综述为任务,评估Llama 3 8B、GPT-4o及定制/微调模型复现人工文献分类的能力,证明微调GPT-4o Mini和Custom GPT可显著提升准确率。

摘要:

本研究通过对环境、社会和治理(ESG)因素与财务绩效之间关系进行系统综述,考察大型语言模型(LLM)在解释现有文献方面的有效性。主要目标是评估LLM如何在一个聚焦ESG的论文语料库上复现系统综述。我们汇编并人工编码了一个包含88篇相关论文的数据库,这些论文发表于2020年3月至2024年5月。此外,我们使用了此前一项关于2015年1月至2020年2月ESG文献的系统综述中的238篇论文。我们评估了两种当前最先进的LLM,即Meta AI的Llama 3 8B和OpenAI的GPT-4o,考察其相对于两组论文上人工分类结果的解释准确性。随后,我们以这238篇论文的语料库作为训练数据,将这些结果与一个“Custom GPT”和一个经过微调的GPT-4o Mini模型进行比较。微调后的GPT-4o Mini模型在提示1上的总体准确率平均比基础LLM高出28.3%。同时,“Custom GPT”在提示2和提示3上的总体准确率分别平均提升3.0%和15.7%。我们的研究结果揭示了令人鼓舞的前景:投资者和机构可以利用LLM总结与ESG投资相关的复杂证据,从而实现更快速的决策和更高效的市场。

英文摘要:

This study investigates the effectiveness of Large Language Models (LLMs) in interpreting existing literature through a systematic review of the relationship between Environmental, Social, and Governance (ESG) factors and financial performance. The primary objective is to assess how LLMs can replicate a systematic review on a corpus of ESG-focused papers. We compiled and hand-coded a database of 88 relevant papers published from March 2020 to May 2024. Additionally, we used a set of 238 papers from a previous systematic review of ESG literature from January 2015 to February 2020. We evaluated two current state-of-the-art LLMs, Meta AI's Llama 3 8B and OpenAI's GPT-4o, on the accuracy of their interpretations relative to human-made classifications on both sets of papers. We then compared these results to a "Custom GPT" and a fine-tuned GPT-4o Mini model using the corpus of 238 papers as training data. The fine-tuned GPT-4o Mini model outperformed the base LLMs by 28.3% on average in overall accuracy on prompt 1. At the same time, the "Custom GPT" showed a 3.0% and 15.7% improvement on average in overall accuracy on prompts 2 and 3, respectively. Our findings reveal promising results for investors and agencies to leverage LLMs to summarize complex evidence related to ESG investing, thereby enabling quicker decision-making and a more efficient market.
