🤖 AI Summary
Existing LLM evaluation in finance struggles to disentangle knowledge acquisition from reasoning capability and lacks fine-grained attribution analysis. Method: We propose the first fine-grained evaluation framework for Chinese financial LLMs, featuring a dual-metric system (“knowledge score” and “reasoning score”), cognitively interpretable scoring grounded in Bloom’s Taxonomy, and an open-source financial reasoning dataset covering 22 subdomains—constructed via integration of a Chinese financial knowledge graph, domain-adaptive prompting, and multi-dimensional error attribution. Contributions/Results: First, we identify a critical bottleneck: finance-specialized models underperform general-purpose LLMs in knowledge transfer applications. Second, empirical analysis confirms that higher-order reasoning ability and cognitive hierarchy are primary determinants of model performance. Third, we demonstrate that state-of-the-art finance-specialized LLMs still lag behind general-purpose counterparts overall.
📝 Abstract
Large Language Models (LLMs) demonstrate significant potential but face challenges in complex financial reasoning tasks requiring both domain knowledge and sophisticated reasoning. Current evaluation benchmarks often fall short by not decoupling these capabilities indicators from single task performance and lack root cause analysis for task failure. To address this, we introduce FinEval-KR, a novel evaluation framework for decoupling and quantifying LLMs' knowledge and reasoning abilities independently, proposing distinct knowledge score and reasoning score metrics. Inspired by cognitive science, we further propose a cognitive score based on Bloom's taxonomy to analyze capabilities in reasoning tasks across different cognitive levels. We also release a new open-source Chinese financial reasoning dataset covering 22 subfields to support reproducible research and further advancements in financial reasoning. Our experimental results reveal that LLM reasoning ability and higher-order cognitive ability are the core factors influencing reasoning accuracy. We also specifically find that even top models still face a bottleneck with knowledge application. Furthermore, our analysis shows that specialized financial LLMs generally lag behind the top general large models across multiple metrics.
